  2. 'Finishing year as number one is unreal'

    Djokovic collects world number one trophy

    Novak Djokovic

    Novak Djokovic might not be playing until tomorrow, but he's already been on court today.

    That's because, at the end of the afternoon session, Djokovic was presented with his trophy for finishing the season as world number one.

    “It has been an amazing season, especially the last five or six months,” said the Serb, who was sporting a golden number one on his white top.

    “It took a bit of time for me to find my confidence and level of tennis that I was looking for and working hard for. Everything seems a bit unreal, to be honest. This is really a dream come true. This is a perfect stage for me to celebrate this trophy with you.”

    Before you hit the hay for the night, here's something to entertain you...

  5. 'Overall I'm hitting the ball alright'

    Federer 6-7 (4-7) 3-6 Nishikori

    Roger Federer after his straight-sets defeat: "The court here plays different, definitely slower than last few tournaments I've played. So everyone is making minor adjustments, including me.

    "I've been feeling fine, just practice was a bit all over the place, practising at Queen's, practising on outside courts here and at Centre as well, so it was not always the same conditions.

    "Overall I'm hitting the ball alright, the warm up today was fine.

    "Maybe both of us had a bit of nerves too, not knowing how to attack second serves, trying to get the right feel for it. Both struggled to get that early."

    Here's what Roger had to say afterwards. He claims he was "feeling fine"...

  7. Post update

    Federer 6-7 (4-7) 3-6 Nishikori

    The saving grace for Federer? He's not on his way to Heathrow to catch a plane back home.

    The world number three has two more matches to play - against his Wimbledon conqueror Kevin Anderson and Dominic Thiem, of course - to turn things around and reach the last four.

    This the fourth time he's lost his opening match at the season-ending finals. One ended in a group-stage exit (2008), another ended in a semi-final defeat (2013) and the other ended up in him winning the thing (2007).

    Never write Federer off...

  8. 'Federer never found his rhythm'

    Federer 6-7 (4-7) 3-6 Nishikori

    Tim Henman

    Former British number one on BBC TV

    I said before the match, for Nishikori to win, Federer had to play way below par and that's what happened.

    Federer never found his rhythm from the back of the court. Nishikori is not a great server, but Federer didn't make a break point in the first set.

    Time and time again we saw errors from the back of the court and not getting his feet into the right areas.

    Nobody expected that, but take nothing away from Kei Nishikori. He played the crunch points and got himself into that tie-break.

    Roger Federer is already in his post-match press conference apparently. He's clearly in a hurry to get this night over with...

  11. Post update

    Federer 6-7 (4-7) 3-6 Nishikori

    Winner Kei Nishikori, speaking to BBC Sport: "I'm glad to win, it is never easy to play with my idol, it is always a big challenge against him, so it was great to win today.

    "The first match of a tournament is never easy, we were both playing a little bit out especially in the first set, but I think I played the second set better.

    "I had to change something against him, I lost twice against him in two months. I played good tennis, using the forehand more and more aggressive and it came together in the second set.

    "I played well today."

    But let's not take anything away from Kei Nishikori. He sensed Federer's frustration and refused to let him off the hook.

    And what was more impressive is how he tweaked his approach to beat Federer after losing to him twice in Shanghai and Paris over the past couple of months.

  13. Post update

    Federer 6-7 (4-7) 3-6 Nishikori

    Federer made 60 errors in less than 90 minutes on court. SIXTY! More than half of those were unforced as well.

  14. Post update

    Federer 6-7 (4-7) 3-6 Nishikori

    Kei Nishikori raises both arms in the air and looks up to the O2 roof with a broad, if also slightly relieved, grin.

    Roger Federer skulks off court without looking up while waving to the crowd. A stinker of a day at the office for the GOAT.

  15. Game, set and match Nishikori

    Federer 6-7 (4-7) 3-6 Nishikori

    One goes begging when Kei Nishikori crumbles first in a baseline rally... but he takes the second!

    And unsurprisingly it is another shank by Federer which enables the Japanese to clinch victory.

    Nishikori shocks an out-of-sorts Roger Federer in straight sets. Well...

    Let's see if Kei can hold his nerve then. A first win over Federer since 2014 is on his racquet...

    Another error from Federer gifts him a 15-0 lead, then a serve and volley puts the Japanese 30-0 in front.

    All of a sudden he has three match points ...

  17. Post update

    Federer 6-7 (4-7) 3-5 Nishikori*

    That's more like it. Federer starts with an ace and then lands another first serve as Nishikori bats a return long for 30-0.

    A deep cross-court backhand can't be returned by Kei... 40-0... although Nishikori then pounces on a second serve with a dipping cross-court backhand.

    Federer smacks down another ace to hold and tells Kei that he'd better serve it out if he wants to win this match....

  19. Moody?

    David Law

    BBC Radio 5 live sports extra commentator at the O2

    Federer is not in the best of moods. Maybe he is just frustrated that he is not able to play the way he wants to play.

  20. Post update

    *Federer 6-7 (4-7) 2-5 Nishikori

    Nishikori is looking strong here. Plenty of variation, keeping Federer guessing. And even when Federer anticipates it, he's not clicking.

    Kei eases 40-0 ahead, then sees a second serve whacked way long by Federer. That was nearer Row A than the baseline.

    Nishikori backs up the break quickly as Federer's mind continues to be elsewhere.
