Thanks for your company this evening. Join us again tomorrow for four more games in the Scottish Premiership, plus all the excitement from the Championship, League One and League Two.
- Griffiths scores twice for Celtic
- Simunovic & Commons also score
- Murray pulls one back for United
- Celtic extend lead at top
- United still 11 points adrift at foot
Asked if in-form Leigh Griffiths might attract transfer bids despite recently signing a new long-term deal, manager Ronny Deila laughed and said: "He is not for sale - that's the price."
"To score four goals away is always difficult and we did well.
"We could have scored more in the end, but I think we lost the ball too much.
"The fans were unbelievable and helped bring the team forward.
"We saw a lot of good play."
"It was massive. The booking was worth it.
"I had the t-shirt ready and there was no way it was not coming off.
"I was disappointed not to be playing last season, but I knew what I had to do to get back in the team.
"But I couldn't do it without my team-mates."
An interesting take on the smoke bombs let off by the United fans from manager Mixu Paatelainen. He admits that "rules are rules" and fans should not be letting them off before adding: "I think that, as long as it is not a safety risk, it adds to the atmosphere."
"I thought the attitude was excellent from the players.
"Celtic defended well and, on a couple of occasions, we got behind them.
"But we were a bit too anxious to make things happen and we gave the ball away cheaply.
"With a bit more patience of the ball, we could have created more chances."
"Dundee United left too much space for Celtic. They could have scored at least three more goals. United had lots of possession, but did they trouble Craig Gordon?"
Celtic move six points clear of Aberdeen at the top of the Premiership after that comprehensive and, perhaps, predictably easy win. The Dons, who have played the same number of games, can reduce the arrears again if they can win away to Ross County on Sunday.
Referee Bobby Madden has a quiet word with Leigh Griffiths at the final whistle, no doubt telling the striker that he had no option but to book him for celebrating his 50th goal for the Glasgow club by taking his top off to show a pre-prepared t-shirt.
There's three minutes of, now, unnecessary stoppage time.
A large portion of the 10,820 crowd has already drifted away from the scene of another painful defeat for the home side.
"Celtic have been so wasteful with chances. They could have been seven, eight, nine on top."
So close to a fifth goal for Celtic as Leigh Griffiths roles a cross-come-shot across the face of goal and Kris Commons just fails to make contact.
Mikael Lustig has to head clear at the back post as United press for a consolation.
United are staggering to the final whistle. Simon Murray was down with cramp earlier and now John Souttar is replaced with what looks like a groin injury, with Paul Paton coming on.
Kieran Tierney is forced off with his arm in a sling. He doesn't look too happy about going off, to the replaced with Honduras international Emilio Izaguirre, despite suggestions that the teenage left-back has had a recurrence of a shoulder injury picked up against Stranraer at the weekend.
It is just all about saving face for United as the tempo of the game falls with the game no longer live as a contest.
