And on that bombshell, it is time for me to bring this live text commentary to a close.
Europa League boring? Nahhh.
And on that bombshell, it is time for me to bring this live text commentary to a close.
Europa League boring? Nahhh.
How can he not take a penalty when he is on the pitch?
Abhishek: Hendo was assigned as penalty taker because Balo didn't start. But obviously Balo is better penalty taker. Studge made a scene
Jamie: Give Balotelli credit, young and in another country and takes the ball off over-rated over hyped English players. Believe.
lomekian: Balotelli is one of the best penalty takers in the world...putting Henderson ahead of him under any circumstances is idiotic.
More from Steven Gerrard talking on ITV: "Credit to Mario, he's scored, but it's not nice to see when footballers are arguing. I think Jordan has handled the situation very well. He can see that Mario really wanted to score. Jordan walked away at the right moment and handled his post match interview very well."
"Jordan is the captain and Mario showed Jordan a bit of disrespect there, but he's scored a very important goal. I think six or seven players would have wanted to take that penalty so if they all say they are taking it, what happens then?! Rules are in place for a reason."
Liverpool captain Steven Gerrard, speaking to ITV: "Jordan should have taken the penalty. Rules are rules. It should have been Henderson. Mario has been a bit mischievous."
When your captain says that, you know you are going to be in bother.
Interesting stuff from Steven Gerrard as well in the ITV studio, says he felt Jordan Henderson should have taken the penalty and did not seem best pleased with Mario Balotelli's actions. More from Gerrard shortly.
Very diplomatic from Jordan there, but it was pretty clear he was not happy with having the ball taken from him.
Liverpool midfielder Jordan Henderson, speaking to ITV: "It was a big goal, I thought we kept the ball well at times and we deservedly got the goal at the end. It was a big goal for us and especially keeping the clean sheet.
"I wanted the penalty, Mario felt confident and he has taken big penalties before. Everyone wants to take them. I felt confident in Mario, he has taken big penalties before and he got the nod."
Holders Sevilla take a slender lead into their second leg tie against Borussia Monchengladbach thanks to a Vicente Iborra goal that gave the Spaniards a 1-0 win.
Guingamp come back from 1-0 down to win 2-1 at home against nine-man Dynamo Kiev, with Claudio Beauvue and Mustapha Diallo giving the French side the advantage heading into the second leg while Ajax beat Legia Warsaw 1-0 after Arkadiusz Milik's first-half effort.
Villarreal defeated Salzburg thanks to efforts from Ikechukwu Uche and Denis Cheryshev either side of a Jonathan Soriano penalty while Anderlecht and Dynamo Moscow play out a goalless draw in Belgium.
Tottenham academy coach on BBC Radio London
"The intensity they will need to put into the return leg to win it will be high. But with the League Cup final only three days later, will Pochettino risk the big players like Kane and Eriksen. But some of Spurs' best performances this season have come away from home, so they won't be phased by this. But God forbid, any of the players get injured and miss the final."
Jordan Henderson takes it, but hits the wall. That's the last action of the game.
Raheem Sterling's tricky feet win Liverpool a free-kick on the edge of the area, a good chance for a second...
What drama! Celtic snatch a late, late equaliser through John Guidetti, who chests the ball down before firing in. Could there be more late drama?
All over at White Hart Lane and not a great result for Tottenham, Fiorentina have the advantage with the away goal.
There will also be three added minutes at Liverpool and the hosts are a little nervy as Besiktas come forward, searching for an equaliser.
Into three minutes of injury time in London. Can Tottenham find a second?
Liverpool have the lead, but could Mario Balotelli's decision to take the ball off Jordan Henderson cause a bit of friction? Henderson was not happy at all, signalling at the bench before Balotelli scored. Henderson tapped Balotelli on the shoulder in the celebration, but looked a little half-hearted.
Nice. Very nice. Taking the ball off Jordan Henderson was a big call by Mario Balotelli. He has to score now and he steps up, pauses slightly, but fires the ball into the net.
Mario Balotelli takes the ball off Jordan Henderson, the striker wants this...
Chance for Liverpool here as Jordon Ibe is fouled inside the area, penalty. But who takes it...?
Raheem Sterling's direct running finally awakens Anfield as he charges forward on a counter, sliding the ball out wide to Daniel Sturridge, who gets into the area but his attempted chip lands on the roof of the net.
For all their dominance, lacklustre defending could be Tottenham downfall in this game. Mohamed Salah is allowed to get inside the area, the legs of Spurs' defenders trying desperately to hack clear, eventually succeedin. A lucky bounce and Salah could have sneaked in there.
Dejan Lovren heads over from a free-kick before Raheem Sterling makes his return from injury, replacing Adam Lallana. He has 13 minutes to make an impact.
This has not been a great half, about the most entertaining thing has been Mario Balotelli's outstanding moustache.
Raheem Sterling is getting ready to come on.
After a breathless first half in which five goals were scored, there's been nothing to add in the second half.
Could there be late drama though? Follow the action via our dedicated live text commentary.
Lovely flick by Roberto Soldado puts Paulinho through on goal but his shot is pushed behind for a corner. Andros Townsend is then substituted, receiving a standing ovation as he goes off after an excellent display, Erik Lamela replaces him.
Steve Howes: So Brendan Rodgers promised the real European Liverpool would arrive six months late. Well so far they've not arrived.
Elton Nkhata: Even if Liverpool lose, I see a good future, especially for Jordon Ibe.
Mark Wilkins: This game needed something, let's hope that super Mario's introduction is the catalyst?
Chance for Fiorentina as Mario Gomez receives a pass midway inside the Tottenham area, breaks into the box and wrongfoots two defenders but his good work is undone when he shoots over the bar.
Villarreal were pegged back by a Jonathan Soriano penalty for Salzburg, but re-establish their lead thanks to a Denis Cheryshev strike at the Madrigal.
No change in the rest of the games since half-time.
Harry Kane is on for Nacer Chadli for the remaining 25 minutes while Marcos Alonso replaces Manuel Pasqual for Fiorentina.
Dejan Lovren and Mario Balotelli do indeed come on, replacing Joe Allen and Philippe Coutinho. Can Balotelli inject a bit of life into this game?
Over in London, Harry Kane is receiving instructions as he prepares to come on. Marcos Alonso is also about to come on for Fiorentina. Alonso was a Bolton player when Fabrice Muamba collapsed on the pitch at White Hart Lane back in 2012.
Dejan Lovren and Mario Balotelli look set to come on. Liverpool certainly need something, they've been very flat in this half.
Tottenham academy coach on BBC Radio London
Harry Kane has become the focal point for the Tottenham attack. If he comes on, he will give the whole team a lift. If they can take a 2-1 lead to Italy they have a great chance to qualify.
Desperate defending by Beskitas as Martin Skrtel shoots goalwards, his shot is blocked before Jordan Henderson drags a shot wide from the edge of the area.
Tottenham have Fiorentina struggling to get out of their own half, they are pinging in crosses like there is no tomorrow but each and every one is failing to find a Tottenham player. Harry Kane o'clock?
Emre Can is struggling with the presence of Demba Ba. He gifts the ball straight to the striker on the edge of the area, but Martin Skrtel is across quickly to make the block.
A chance for Tottenham as Christian Eriksen tries to dance his way through a crowd of players inside the area, but fails.
How did he not score that!? Liverpool have a glorious chance as Jordan Henderson gets away down the wing, sends the ball into the area and a defensive mix-up sees goalkeeper Cenk Gonen stranded and Adam Lallana running on to a loose ball. He has an open goal in front of him but smashes the ball well over the bar from close range. Should have done better.
Fiorentina attack from the off as Mohamed Salah lets fly with a curling effort from the edge of the box, just wide.
Second halves are under way in tonight's Europa League games.
Besiktas managed to hold Tottenham in the Europa League group stage to a 1-1 draw in their away leg earlier this season and they are again holding their own against English opposition. Can Liverpool find a breakthrough?
Everton boss Roberto Martinez: "It was a test of character to go behind to a team in great form at home. It was a great result. When you see us play like that, we get back to memories of last season. In the league we have felt cagey. Europe is a fresh challenge."
"I have always said that Romelu Lukaku is an important player for us. He ticks every box - he is the complete striker."
"Bryan Oviedo has put a lot of work in since he has come back. He has had a normal reaction to just coming back from injury. John Stones will learn from his sending off. It will help him in the long run. Even with 10 men we were positive."
Will Fiorentina look to nullify Andros Townsend more effectively in the second half? He had plenty of joy down that right flank in the first 45 minutes.
It is hammering it down at White Hart Lane, but Roberto Soldado won't care what the weather is like there, he'll probably play in anything given his home record - 10 of his last 11 goals for Spurs have been scored at White Hart Lane.
Tottenham academy coach on BBC Radio London
I think Spurs can be encouraged by the high tempo and play, but Fiorentina are still in it, so Spurs have to be careful if they start chasing it. I think Harry Kane will be thrown into the action in the last 15/20 minutes.
Ajax go into half-time with a 1-0 lead over Legia Warsaw thanks to a goal from Arkadiusz Milik while Villarreal lead Salzburg 1-0 at the interval after Ikechukwu Uche's goal.
Dynamo Kiev enter the break 1-0 up at Guingamp after Miguel Veloso's effort, but end the half with nine men after red cards for Andriy Yarmolenko and Younes Belhanda.
Europa League champions Sevilla end the first-half 0-0 with Borussia Monchengladbach, and it is also goalless in Belgium, between Anderlecht and Dynamo Moscow.
Oh dear Nacer Chadli! He won't want to see this chance again in a hurry. Roberto Soldado's header is pushed to Chadli's feet by Ciprian Tatarusanu, but he somehow clips the ball onto the bar with an open goal in front of him.
Inter are back ahead in this enthralling first half, but it is not a moment for Craig Gordon's scrapbook, he can't hold a ball into the box and Rodrigo Palacio is on it to poke into the unguarded net.
Great save by Cenk Gonen! A Liverpool corner is poked out of the area by Gokhan Tore and Alberto Moreno is on it. He is miles outside the area but connects with the ball superbly to send a rasping drive that Gonen has to push over.
Pieter Troffaes: Wall doesn't jump, the whole Tottenham defence caught watching and three Fiorentina players all by themselves, that's poor.
Phuckle: Liverpool without pace are just a slow team that doesn't look like scoring.
Javel Bleach: Coutinho could dribble his way through a squadron of supersonic MIG fighter planes!
Liverpool have a free-kick on the right side of the area and Daniel Sturridge fancies it, but he curls the ball just over the bar.
Tottenham academy coach on BBC Radio London
Really scruffy goal and really sloppy play. Fiorentina really haven't deserved that goal but having said that through all the dominance they have had, Spurs haven't created many chances.
BBC Scotland's Alasdair Lamont: Wow. 60 seconds is a long time in football! Inter were absolutely cruising and all of a sudden they're punch-drunk. This game is back on and how!
Fiorentina hit back, and it is against the run of play. It is a disappointing goal as far as Tottenham are concerned as Jose Maria Basanta scrambles home in a crowded box after Hugo Lloris had denied a fierce drive seconds earlier.
Demba Ba. Liverpool's tormentor almost scores again at Anfield as he runs on to a through ball and uses his pace to power through the defence. He shoots low from outside the box but Simon Mignolet does superbly to push it behind.
Liverpool are also having plenty of freedom out wide, but their final ball is lacking. Instead it is Besiktas who go closest to an opening goal as Veli Kavlak powers a header just over from Ersan Gulum's corner.
Fiorentina are struggling to deal with Andros Townsend on the right wing. The Spurs man is allowed to run down the line and then cut inside to the edge of the area. Still defenders back off so Townsend has a go at goal, but his shot is deflected wide.
Not much going on elsewhere in the Europa League, though Dynamo Kiev have scored at French side Guingamp, leading 1-0.
The rest of the games remain goalless.
This looks a chance for Liverpool! Philippe Coutinho sees a gap in the defence and plays the ball for Alberto Moreno to run on to, but he is offside.
Scenes at Celtic Park as two goals in two minutes bring the hosts level. Stefan Johansen loops the ball into the box following a throw-in and Stuart Armstrong puts enough pressure on Hugo Campagnaro to make the Inter defender knock into his own goal at the near-post. What a noise at Celtic.
Adam Matthews bursts down the right brilliantly for Celtic and cuts the ball back into the box where Stuart Armstrong is there to mark his European debut for the club with a simple finish.
Ash Williams: Inter are proving why Scottish teams should not be in European competition. A hammering coming up!
Toyosi Levi: As a Liverpool supporter, I prefer the Europa League over the Champions League.
Edward Parham: Nice seeing Soldado score so early on in this tie! Surely that will be a massive confidence boost!
No clear cut chances as yet at Anfield but Jordon Ibe has been very impressive in the opening exchanges. He has been heavily involved in almost all of Liverpool's attacks, although those have been few and far between. It is all pretty cagey.
Tottenham are back on the attack as first Christian Eriksen shoots over the bar before a Roberto Soldado brimming with confidence goes for an overhead, but hits it straight at Ciprian Tatarusanu in the Fiorentina goal.
BBC Scotland's Alasdair Lamont: Celtic Park is in something of a state of shock at the loss of those two early goals. Celtic have been in such good form, recording eight successive domestic wins, but they haven't faced a team as good as this for some time and it shows.
Tottenham academy coach, on BBC Radio London
"Ever so slowly Fiorentina are creeping back into the game. Salah, on loan from Chelsea, is looking good for them. However it may well play into Spurs hands if they start to over commit."
Great reaction from Jan Vertonghen to deny Mohamed Salah for Fiorentina. The midfielder, on loan at the Italian side from Chelsea, gets a lucky bounce inside the Spurs area to put him clear on goal but Vertonghen is back quickly to divert his effort behind.
Besiktas build their first real attack as Gokhan Tore's high ball finds Demba Ba on the edge of the area. He holds the ball up, but can't find a team-mate as Liverpool clear.
Xherdan Shaqiri has a shot blocked by Craig Gordon but from the resulting corner the same player knocks the ball back into the box and Argentine Rodrigo Palacio reacts quickest to bury it beyond Craig Gordon.
Fiorentina cannot get the ball out of their half with Tottenham well in control. Roberto Soldado's cross goes over the bar, before an effort by the lively Paulinho is blocked.
A stoppage in play at Anfield as a pitch invader races on. Cheers from the home crowd as, I guess, the culprit is caught by a steward and we are soon back under way.
Bradley Allen, former Premier League striker on BBC Radio London: "Harry Kane would be proud of that finish from Soldado. That was a £26m finish. Roberto take a bow. If Spurs continue on the front foot like this, they can put the tie to bed."
Liverpool left back José Enrique: Come on boys!!!
Great start for Tottenham! Paulinho swings in a corner and Roberto Soldado is left unmarked to volley in through a crowd, 1-0 Spurs.
It is a strong side that Brendan Rodgers has named. He clearly wants to do well in the Europa League and he is rewarded for a strong selection as Liverpool forge an early chance. Jordan Ibe, on his European debut, feeds a pass to Daniel Sturridge, who wriggles past a defender and shoots powerfully at the keeper. Good start.
It's the start the hosts were dreading as Xherdan Shaqiri squeezes home an effort to give Inter the lead. Zdravko Kuzmanovic knocked the ball over the top and Shaqiri tried a left foot shot that goalkeeper Craig Gordon blocked back into the forward's path, and he made no mistake second time out with a neat low finish.
All the 20:05 GMT games are just getting under way now...
History suggests Tottenham fans won't be witnessing a defeat tonight. Can Spurs keep up their impressive record against Italian sides?
Liverpool's Steven Gerrard, speaking on ITV1: "I know Demba Ba better than most. He is a top player, he is always a threat and it is very important we keep him as quiet as we can."
Anfield is ready for the start of Liverpool's Europa League adventure. Can they kick it off with a win? The two teams are strolling out of the tunnel to a typically fantastic atmosphere.
BBC Radio 5 live
Jonathan Northcroft, Sunday Times football correspondent, on the Wednesday Night Club on 5 live Sport: "I saw Daniel Sturridge play at Crystal Palace and he was impressive in the sense that he looked rusty to start with and struggled a little bit, but he dug in and ended up playing really, really well - he got better as the game went on and made a real impact in the second half.
"He's certainly looked up to by some of the younger Liverpool players, and he's the leader of a pack of the likes of Raheem Sterling and Jordan Ibe. Sturridge is someone who likes to feel loved and wanted. They missed him so much when he was injured and how he's returned to players and fans who have welcomed him back with open arms.
"For Liverpool to be successful he has to now be a leader. They are losing Steven Gerrard and so they need players like him to now step up."
Burnley defender Steven Reid
Wednesday Night Club, 5 live Sport
"Playing in the Europa League followed by a league game at the weekend is tough. If you haven't a squad who can deal with that then it can be a problem.
"But now they Liverpool have Daniel Sturridge back, and they look a different team. Over the last few weeks they've been quicker on the break and are playing with that pace we saw last season. Maybe when he plays his fellow players play differently, because they know where he's going to be and they can react to his movement.
"It's obviously a massive boost for them that he's back in there."
Will Demba Ba come back to haunt Liverpool? He, of course, scored that goal after Steven Gerrard's slip to damage Liverpool's title hopes last season.
Reds boss Brendan Rodgers is not thinking about that moment too much, though, saying: "It won't stimulate any bad memories for me. At the time (last April) he scored a goal, which was a good goal, but he has scored many good goals in his career.
"We just see him as a threat that we will pay respect to but nothing more than that. He had a very good period here in England, he is a wonderful player, who has good touch and technique and he scores goals. He has gone to Besiktas and done well."
Tottenham Hotspur: The players are out warming up as the stands fill up inside White Hart Lane.
A great win for Everton, can their Premier League rivals follow suit? Liverpool and Tottenham kick-off their last-32 games against Besiktas and Fiorentina respectively in just under 15 minutes.
Europa League holders Sevilla are yet to lose at home to a German side in European competition as they prepare to welcome Borussia Monchengladbach in the round of 32 while Dutch champions Ajax prepare to face Polish opponents for the first time in Europe as they take on Legia Warsaw.
Villarreal are unbeaten in three European home games this season whilst tonight's opponents Salzburg have won all three of their Europa League away fixtures this season.
Russian side Dynamo Moscow will look to extend their 10-game unbeaten run in Europe as they travel to Anderlecht while French Cup winners Guingamp have made it to the knockout stages of European competition for the first time and prepare to host Dynamo Kiev in Brittany.
BBC Scotland's Alasdair Lamont: European nights at Celtic Park this season have lacked the sparkling intensity of recent seasons - the Europa League will do that. But this evening feels different. The prospect of facing a genuine European giant - albeit a slightly diminished one - has increased the sense of anticipation about the stadium and it could be reminiscent of a big Champions League night.
All over and it is more Merseyside misery for the hosts. Everton become the first team to win in Bern since Liverpool in 2012.
Everton come forward through Steven Naismith in pursuit of a fifth. He passes to Luke Garbutt, who then loses possession. That's probably the last attack of the game.
Three minutes of added time and Everton are looking good to head back home with a three-goal cushion ahead of the second leg.
Worth remembering that Young Boys were ridiculously strong at home. They had scored 13 goals and conceded just one in their five previous Europa League matches in Bern this season and have been well beaten tonight.
Celtic Football Club: The legends of '67 will be hoping that, tonight, Celtic Park will be celebrating the heroes of 2015.
Don't forget Celtic also host Inter Milan in the Europa League this evening and you can follow a dedicated live text commentary here.
It promises to be some atmosphere at Celtic Park.
That's Romelu Lukaku's last action of the game and he gets a deserved round of applause as he heads off the pitch with three goals to his name.
Christian Atsu, who was player of the tournament at the Africa Cup of Nations, is on in his place. He scored an absolute belter at the Afcon, worth a look if you have not seen it!
Steven Naismith is nails. He runs off his injury and moments later Everton are so close to a fifth. Romelu Lukaku powers away from the home defence and tries to lift the ball over Yvon Mvogo, who makes a great save.
Steven Naismith is down clutching his leg after overstretching to challenge for possession. The result may be good, but some of these injuries may be a concern for Roberto Martinez.
Looks like Christian Atsu, fresh from returning from the Africa Cup of Nations where he helped Ghana to the final, is about to come on.
Yellow card for Romelu Lukaku. Not sure what for, even he doesn't seem to know what for as he shrugs his shoulders at the referee in disbelief.
Another change for Young Boys as Tauljant Sulejmanov replaces Renato Steffen for the final 12 minutes.
Alex Barton: Who says the Europa League is boring? Red card, missed penalty, and a perfect hat trick. That's entertainment!
Scrap that, they get forward as Romelu Lukaku goes for a fourth but he is offside as he heads wide from a cross.
Alexander Gerndt again has a chance, but the effort is blocked for a corner. Everton are not being adventurous now they are down to 10 men.
Kazim Kazim-Richards (formerly Colin in his days in English football) has bagged an equaliser for Feyenoord in Roma, cancelling out Gervinho's first-half strike to leave the scores locked at 1-1 at the Stadio Olimpico, while Hulk has given Zenit St Petersburg a 1-0 lead at PSV Eindhoven.
A brace from Bas Dost has put Wolfsburg 2-0 up against Sporting Lisbon and a Kenneth Petersen own goal has increased Club Brugge's lead to 3-0 at Aalborg while Jaba Kankava and Ruslan Rotan have put Dnipro 2-0 up at home to Olympiakos.
Torino still have a 2-1 advantage over Athletic Bilbao while Napoli have not yet extended their 3-0 lead at Trabzonspor in the second half.
A fine introduction to the game by Alexander Gerndt as the former Swedish player of the year meets a cross to volley a shot straight at Tim Howard. A little more to the left or right and that would have been 4-2.
Antolin Alcaraz is on for James McCarthy as Robert Martinez makes his second change. Young Boys also make a change as Milan Gajic is replaced by striker Alexander Gerndt.
Romelu Lukaku should have his fourth! Substitute Luke Garbutt crosses low from the right and the bounce on the artificial pitch catches out the Young Boys defender but also surprises Lukaku, with the ball bouncing off his foot and wide from barely four yards out.
Celtic start with the same XI as the one that began the match against St Johnstone on Saturday. That means European debuts in a Celtic jersey for Gary Mackay-Steven and Stuart Armstrong and Leigh Griffiths keeps his place up front.
The only slight surprise in the Inter Milan line-up is the inclusion of Rodrigo Palacio ahead of Mateo Kovacic.
Celtic XI: Gordon; Matthews, Denayer, van Dijk, Izaguirre; Brown, Bitton; Mackay-Steven, Johansen, Armstrong; Griffiths.
Inter Milan XI: Carrizo; Campagnaro, Ranocchia, Juan Jesus, Santon; Medel, Guarin, Kuzmanovic; Shaqiri; Palacio, Icardi.
Oh my. A terrible, terrible penalty by Guillaume Hoarau. This was a golden chance to get his side back into the game but he steps up far too casually to launch the spot kick high and wide.
Penalty to Young Boys as John Stones brings down Guillaume Hoarau. Stones is also red carded. Big chance for the hosts to get back into this....
Tottenham boss Mauricio Pochettino has left in-form striker Harry Kane on the bench as he hands Roberto Soldado a chance to impress in attack as part of six changes from the side which lost 3-2 at Liverpool last time out.
Ben Davies and Federico Fazio come in for Eric Dier and Danny Rose in defence while Andros Townsend, Nacer Chadli and Paulinho come in for Ryan Mason, Mousa Dembele and Erik Lamela in midfield.
Fiorentina coach Vincenzo Montella gives a Europa League debut to Egypt winger Mohamed Salah, who has joined on loan until the end of the season from Chelsea as part of the deal which took Juan Cuadrado to Stamford Bridge.
Manchester City defender Micah Richards, who is on a season-long loan with the Florence club, is named among the substitutes for the visitors at White Hart Lane.
Tottenham XI: Lloris, Walker, Fazio, Vertonghen, Davies, Bentaleb, Paulinho, Chadli, Eriksen, Townsend, Soldado.
Fiorentina XI: Tatarusanu, Rodriguez, Basanta, Savic, Pizarro, Joaquin, Fernandez, Valero Iglesias, Pasqual, Salah, Gomez.
Freddy Howard: Important Everton leave Switzerland so they have an easy second leg - gives them the opportunity to concentrate on vital Premier League matches.
Matt Austin: I think the reason Everton look better tonight is because in the league teams have learned that sitting deep nullifies us. Not so in Europe.
Romelu Lukaku completes a great night as he scores his third of the game and it is a typical Lukaku strike. He charges away on the attack, gets beyond a defender to leave him one-on-one and he sidefoots home.
A few Young Boys players seem unhappy, though, as it appeared some had stopped as James McCarthy was down injured and needed treatment.
Bryan Oviedo limps off and, as expected, on comes Luke Garbutt.
It looks like Bryan Oviedo's game is over. He has injured his hamstring having bumped Renato Steffen off the ball to prevent him crossing. Luke Garbutt is instructed to warm up quickly.
A chance for Everton as Bryan Oviedo sends a cross into the area, Steve von Bergen tries to head the ball away but only as far as Kevin Mirallas, unmarked on the right side of the area, but he lashes his shot wide.
Ross Barkley is booked but it could have been much worse. The Everton midfielder was down on the ground after a challenge and got knocked in the head by the trailing foot of Sekou Sanogo. Barkley gets up and pushes Sanogo and out comes the yellow card and the referee screams a warning at Barkley.
Tim Howard's first action of the second half is to help a speculative cross-shot over the bar. It looked like it was going over, but he couldn't be too sure. The subsequent corner comes to nothing.
Liverpool striker Daniel Sturridge makes his European debut for the Reds having missed the whole of their Champions League campaign through injury.
Reds boss Brendan Rodgers makes one change from the side which beat Crystal Palace in the FA Cup with Jordon Ibe in for the suspended Lazar Markovic. Raheem Sterling is back on the bench following a recent foot injury.
Besiktas coach Slaven Bilic includes Demba Ba in his starting line-up after the striker shook off a slight knock. It will be the first time Ba has faced Liverpool since scoring for Chelsea last year in a win which damaged the Reds' title hopes.
Liverpool XI: Mignolet, Can, Skrtel, Sakho, Allen, Henderson, Moreno, Ibe, Coutinho, Lallana, Sturridge.
Besiktas XI: Gonen, Kurtulus, Franco, Gulum, Motta, Hutchinson, Kavlak, Tore, Sosa, Sahan, Ba.
Can the second half live up to the first? Will Romelu Lukaku complete his hat-trick?
We are back under way.
Striker Harry Kane starts on the bench for Tottenham against Fiorentina.
Tottenham XI: Lloris, Walker, Fazio, Vertonghen, Davies; Bentaleb, Paulinho; Chadli, Eriksen, Townsend; Soldado.
Is Napoli's tie with Trabzonspor all over at half-time in the first leg? The Italian club lead 3-0 thanks to goals from Henrique, Gonzalo Higuain and Manolo Gabbiadini.
A brace from Maxi Lopez has given Torino a 2-1 lead over Athletic Bilbao, who took the lead through Inaki Williams. Gervinho has put Roma are 1-0 up at the break against Feyenoord, while Obbi Oulare and Lior Rafaelov have given Club Brugge a 2-0 lead away at Aalborg.
The other two early kick-offs are goalless at the interval, and if you want to keep up to date with the goals as they go in visit our live scores page here.
Just away from tonight's game, Chelsea ban three supporters from Stamford Bridge after fans of the club appeared to prevent a black man from boarding a Paris Metro train.
Life banning orders will be issued if there is deemed sufficient evidence of the fans' involvement in the incident, the football club said. Police are investigating the incident.
The current scene at Anfield ahead of tonight's Europa League last 32, first-leg clash with Besiktas.
Liverpool striker Daniel Sturridge makes his European debut. Raheem Sterling, who had a late fitness test, is on the bench.
Liverpool XI: Mignolet, Can, Skrtel, Sakho, Allen, Henderson, Moreno, Ibe, Coutinho, Lallana, Sturridge.
James Fearon: We've scored lovely goals but this linesman is absolutely shocking.
Just caught a replay of Sekou Sanogo's effort that hit the post. It was far too fast to spot in real time but it was actually great defending on the line by James McCarthy. He didn't know much about it as the ball struck his knee and flew onto the post, but he was in the right place at the right time.
Former Everton midfielder
Toffees on fire!
Half-time already? That was great entertainment and I suspect there are more goals to come in the second half.
Everton are playing some great football going forward but their defence is a little suspect. They fail to defend a free-kick properly and Sekou Sanogo picks up a loose ball, no-one closes him down, and he drives an effort through a crowd of players and onto the post. A let-off for the Toffees.
The hosts have a pop from distance, Milan Gajic fizzing in a low effort from well over 30 yards and it needs Tim Howard to get down and push the ball behind for a corner.
Everton are rampant and add a third with another lovely move. This time Bryan Oviedo backheels the ball into the path of Gareth Barry, whose cross deflects to Romelu Lukaku and he taps in. Three important away goals for the Toffees.
'Oooooohs' from the home crowd as Guillaume Hoarau glances a header wide of the post. That was not far off at all.
The Europa League is pointless? This game is putting forward a solid counter argument with play quickly swinging from one end to the other. Both sets of players are getting stuck in too, as Steven Naismith highlights when he goes in heavy on Florent Hadergionaj. Yellow card.
David Spencer: Fantastic game of football this. If the pitch is having anything to do with it, then we need more artificial pitches in England.
This game is very open and Young Boys are only denied an equaliser thanks to a fantastic double save by Tim Howard. First, Howard gets a hand to push away Guillaume Hoarau's low shot before then smothering the follow up from Raphael Nuzzolo.
Napoli are already in a good position in their tie away to Trabzonspor having grabbed a 2-0 lead thanks to goals from Argentina forward Gonzalo Higuain and Brazilian defender Henrique.
There have also been a couple of early goals in Torino's clash with Athletic Bilbao which is locked at 1-1 after Maxi Lopez cancelled out Iaaki Williams' opener for the Basque side.
Gervinho has drawn first blood for Roma to give the Italian club a 1-0 lead over Feyenoord at the Stadio Olimpico
David Anderson: Great support here for Everton.
Double blow for the hosts as Everton grab a swift second! It is a lovely move too as Steven Naismith crosses across the face of goal and Seamus Coleman pokes in at the far post. Replays show Naismith had come in from an offside position in the build-up to that goal, though. Controversy.
Jan Lecjaks floats a ball into the area as the hosts push forward, it is aimed at Guillaume Hoarau but the ball is too close to Tim Howard who claims comfortably.
Great response by Everton! They've been trying to find the head of Romelu Lukaku with a few crosses and it eventually pays off as Gareth Barry swings the ball in, Lukaku rises and nods beyond Yvon Mvogo.
Everton have a free-kick, some 30 yards from goal. It looks too far to trouble Yvon Mvogo but Ross Barkley has a go, hitting the wall and the ball deflects behind.
Andy McNamara: This is the best we have played for a while and we are one down. We will score.
There are definitely more goals in this game as Everton again come forward, this time Romelu Lukaku pokes the ball through the defence for Ross Barkley, who tries to cut it back to James McCarthy but Yvon Mvogo is off his line to grab the ball.
Much better! Two chances in quick succession for Everton as Romelu Lukaku uses his strength to evade a couple of challenges on the edge of the area, he then hits a shot low and hard towards the corner but Yvon Mvogo palms it away before then holding Ross Barkley's fierce drive seconds later.
The home fans have found their voice after that goal. Everton try to respond as a ball from defence is pumped forward, but Kevin Mirallas is offside.
That's why their home record is so impressive - first chance, first goal for the hosts. Raphael Nuzzolo tees up Guillaume Hoarau on the edge of the area and, with no defenders closing him down, he curls a shot into the far corner.
Bryan Oviedo is being given lots of space on that left side, and seems keen to cross early. He sends the ball in again from out wide, picking out Romelu Lukaku, but the striker had just strayed offside.
The corner comes to nothing but Everton are quickly back on the attack as Bryan Oviedo attempts a cross, but it almost ends up being a freak goal as the ball smashes the outside of the post.
Under the lights, and on the artificial pitch, this looks like a massive game of five-a-side.
The ball definitely bounces a little differently on this surface than it does on grass but Everton have adapted well to it and have the first chance as Romelu Lukaku shoulders a cross towards goal, but Yvon Mvogo pushes it behind for a corner.
Everton get things under way. Can they move a step closer to some continental silverware?
Everton manager Roberto Martinez, speaking to ITV4: "The artificial pitch has affected the preparation because it's a different turf and the bounce of the ball is different. Back home, we trained on a similar surface for three days and yesterday we tested it again here. It shouldn't be an aspect of the game we worry about. It's about making sure how quickly we can be ourselves in this game.
"Young Boys are a really well-structured side with a terrific balance throughout the team. They want to win games. They go out to score goals. It's fair to say they are very good at what they do. The surface helps them in the way they want to play and they use that to their advantage. I saw them live against Grasshoppers last weekend and they are in a confident moment."
Out walk the two teams at a very lively Stade de Suisse, lots of yellow flags being waved by the home fans. Kick-off in our first Europa League last-32 games is a few minutes away.
Everton warm up in front of the travelling Evertonians - 3,700 have travelled over for this game.
Bolton boss Neil Lennon
Wednesday Night Club, 5 live Sport
"Everton have to be careful. The Europa League takes it out of you with all its Thursday night games. If you play in Switzerland on Thursday night then you won't get home until two in the morning. On Friday you can't do anything, Saturday is a recovery day then bang, it's matchday on Sunday. They just have to be careful, the Toffees, looking at their league position.
"It's all about recovery for your players, both mentally and physically. If they played on a Wednesday then I promise you, that extra day's rest makes you a 30% better player.
"And Everton aren't used to this, the intensity of European competition. And Everton are playing on a plastic pitch, too."

Is there anywhere in the world where a half-and-half football scarf does not exist?
Some 3,700 Everton fans have made the trip to Bern for the game.
Some disturbing news from Rome where 22 Feyenoord fans have been arrested and eight charged ahead of tonight's clash with Roma at the Stadio Olimpico.
Hundreds of Feyenoord fans clashed with riot police at the Spanish Steps before the game. Police fired tear gas and tangled with fans, who left the square's Baroque fountain full of empty beer bottles.
Feyenoord "should make a public apology" and "pay for the damage" said Livio Ricciardelli, a member of the city government, who said that repairs to the fountain at the bottom of the Spanish Steps would be costly.
In one of the ties of the round Roma host Feyenoord in the first leg at the Stadio Olimpico, Torino welcome Athletic Bilbao while Napoli are on the banks of the Black Sea for their clash with Trabzonspor.
Borussia Monchengladbach, roared on by a reported 10,000-strong away support, face Sevilla while Wolfsburg host Sporting Lisbon and Villarreal welcome Red Bull Salzburg to El Madrigal.
Tonight's other fixtures are PSV Eindhoven v Zenit St Petersburg, Ajax v Legia Warsaw, Aalborg v Club Brugge, Dnipro Dnipropetrovsk v Olympiakos and Guingamp v Dynamo Kiev.

Tottenham boss Mauricio Pochettino is not bothered about a congested fixture schedule, with his side playing Fiorentina in the first of six games in 17 days.
Spurs' schedule also includes the return leg against Fiorentina, the League Cup final against Chelsea on 1 March and three Premier League games.
"It's a good sign we are in all competitions. I am happy," says Pochettino. "All the squad are fit and we are in a very good way."
David Morgan: Fulham embraced it.Their philosophy was they were paid to play football so shouldn't complain of tiredness with more matches.
SpursBlood: Going far in the competition then getting knocked out is useless so it is an unnecessary annoyance. Rather no Europa at all.
The visit of Besiktas tonight also means the first return of striker Demba Ba to Anfield since scoring for Chelsea last year in a win which damaged the Reds' title hopes.
Ba's goal at Anfield in April arrived when he pounced on a Steven Gerrard mistake to score the first in Chelsea's 2-0 win in the Reds' penultimate home game of the season. He has 13 league goals and is joint-top scorer in Turkish football this season.
"It won't stimulate any bad memories for me," said Rodgers, when asked what facing Ba would mean. "We just see him as a threat that we will pay respect to but nothing more than that."
Liverpool, of course, have been parachuted into the Europa League after exiting at the group stage of the Champions League.
The Reds picked up just five points but have improved a lot since then, heading into tonight's game against Beskitas on the back of six wins from their last 10 Premier League games, and boss Brendan Rodgers reckons Liverpool could have won the Champions League had they reached the last-16.
"You just never know with the Champions League because sometimes it's not the best teams that win it," he said. "I felt if we were maybe the team we had (last year) or were further down the road with this team then we'd have had a chance with the Champions League, that's the reality."
Will playing on an artificial pitch affect Everton?
Roberto Martinez has been preparing for the Stade de Suisse surface by training for a week on Rugby League side Widnes Vikings' AstroTurf surface, and has also given Harry Redknapp a buzz for some advice. Redknapp was in charge of Tottenham when they played on the pitch five years ago.
"We have done our preparation right," says Martinez. "We have been working on that sort of surface and I feel we are ready. It is not an excuse or a reason for us not to be able to compete in the game."
BBC Radio 5 live
Jonathan Northcroft, Sunday Times football correspondent, on the Wednesday Night Club on 5 live Sport: "Everton are probably suited to European football, but that's a bit of a backhanded compliment really because they have been a bit soft this season in the Premier League. They have been easy to play against, something you don't associate with Everton.
"But Roberto Martinez is very enthusiastic about the Europa League. He loves the concept of it. And there's already talk on Merseyside of another derby, if both Everton and Liverpool and Everton can get through. We'll all be writing more Steven Gerrard pieces.
"That would be a great tie, wouldn't it, an Everton v Liverpool quarter-final?"
Former Everton captain Phil Neville: "It annoys me, you may work for nine months, get into Europe, celebrate and then come back for pre-season and the Europa League has become a noose around the neck.
"We embraced the competition at Everton and that is what you have to do."
Alex W: Europa League affects league form if your squad isn't deep or committed enough to compete on multiple fronts al la Newcastle...
It is not going to be easy for Everton against a side who are strong at home.
They have won their last seven European home games since losing to Liverpool in September 2012, while they have scored 13 goals and conceded just one in their five Europa League matches in Bern this season.
Young Boys's Switzerland international right-back Scott Sutter was born and raised in England, moving to Switzerland in 2002. He apparently supports Tottenham too.
Everton midfielder James McCarthy makes only his second start of 2015 as manager Roberto Martinez looks to nurse him back to full fitness after long-term hamstring trouble. He replaces Mo Besic, while Kevin Mirallas comes in for the cup-tied Aaron Lennon.
BSC Young Boys, second in the Swiss Super League and on a run of eight wins in nine matches, are unchanged from the side who beat Grasshoppers 4-2 last Saturday. France international striker Guillaume Hoarau, who spent four years with Paris St-Germain, scored twice in that win to take his goal total for the season to 11. Centre-back Steve von Bergen played for Switzerland at last summer's World Cup.
BSC Young Boys XI: Mvogo; Hadergjonaj, Vilotic, Von Bergen, Lecjaks; Steffen, Sanogo; Steffen, Kubo, Nuzzolo; Hoarau.
Everton XI: Howard; Coleman, Jagielka, Stones, Oviedo; McCarthy, Barry; Mirallas, Barkley, Naismith; Lukaku.
