You can catch highlights and analysis from today's two Scottish Premiership matches on BBC Scotland at 19:15. We'll chuck the programme up online too.

That's a wrap from me. Thanks for your company. We'll do it all again on Tuesday and Wednesday.

Dundee United manager Liam Fox tells Sportsound: "We want to win every game we're involved in. Today we're playing against a top side. I was pleased to get in at 0-0 at half-time, I thought in the last parts we were just surviving.

"We had to be braver on the ball, better in possession, because we didn't threaten enough for my liking. We conceded two quick goals and the rest of the afternoon becomes very difficult.

[On Jota goal] "I think we should try and stop the cross, first thing. Birighitti has misjudged it and we drop the runner so it's a free header. Like any goal, three or four things go wrong.

"I can't take positives right now, I'm sore and disappointed. We've got a huge game on Wednesday so we have no time to feel sorry for ourselves. There's loads of big games coming. I don't think today will define our season."

Celtic will be at home to Livingston on Wednesday.

Dundee United will need to recover quickly for a big game against relegation rivals Kilmarnock on the same evening.

Celtic manager Ange Postecoglou tells Sportsound: "I thought we handled it well, difficult conditions. They were really disciplined in their structure, particularly the first half. Having said that, we still got behind them on a number of occasions. We missed that final touch and quality. We started the second half really well, scored a couple goals could have scored a couple more. A really strong performance.

"I made a conscious decision a few weeks back not to [talk about VAR]. All I can control is the football my team plays and we put the result beyond anything that can interfere with the result, and that's what we're doing.

"Jota is getting back to fitness and the levels we know he can get to. Aaron [Mooy] has been outstanding since the break. In general, our defensive work was outstanding in terms of our pressure. We didn't allow them many sights on goals and that allows us to play our football.

[On Callum McGregor] "I know I dismissed it (the 400 game mark) before the game, but I said to the lads in there that they've got to appreciate they're sharing a dressing room with a special individual. He'll go down as a legend of this club. The biggest compliment I can pay him is he plays every game like it's his debut, as if he has everything to prove. He's done it all here in Scotland. It's a credit to him and his family."

I think Aaron Mooy gets in before O'Riley and even Hatate at the moment. He's found a great rhythm since the World Cup.

Callum McGregor can take the ball in any situation. For all of the good players they have, he is key to the brave way Celtic play, getting the ball forward so quickly.

You never tire of watching him.

"I'll just keep going until someone tells me to stop," Celtic captain Callum McGregor tells Sky Sports after his 400th appearance for the club.

Aaron Mooy has really kicked on for Celtic since Christmas, with five goals.

The Aussie midfielder kept Matt O'Riley out of the side today and rewarded his gaffer with a converted penalty and an assist for the opener.

So, Celtic make it 21 wins from 23 in the league this season. The Premiership leaders have gone 16 unbeaten since their one defeat away to St Mirren back in mid-September.

That's 50 Scottish Premiership wins for Celtic boss Ange Postecoglou - and it's taken him 61 games.

Only Martin O'Neill (59) has got to that mark quicker for Celtic.

Brendan Rodgers did it in 61 too.

Celtic controlled the game. Callum McGregor was immense in the middle of the park. I don't think he gave the ball away once.

Celtic restore their nine-point lead at the top of the Scottish Premiership with a comfortable win.

United battled hard but didn't really lay a glove on the champions.

Jota nodded in the opener just after the interval and the second came from Aaron Mooy's penalty soon after.

Wait a minute, it should really be three for Celtic as Daizen Maeda steers a header wide from close range.

Celtic not exactly bursting a gut for a third, United just want to hear the whistle...

Five minutes added on at Tannadice...

It's not been a great day for Kieran Freeman as the Dundee United full-back, who gave away a daft penalty, slashes horribly wide of goal after a slack slap away from Joe Hart.

They haven't chucked it, Dundee United. They have kept at it, they've not had many opportunities, but they've certainly worked extremely hard and that's something Liam Fox will be happy about.

A lazy trip on Matt O'Riley earns Jamie McGrath a place in Don Robertson's wee black book.

Oh Hyeon-gyu is on for his Celtic debut and he's joined by Sead Haksabanovic.

Liel Abada and Kyogo trot off.

Daizen Maeda is up impressively to meet a Matt O'Riley corner but his header zips into the arms of Mark Birighitti.

The Celtic sub had the freedom of the penalty box there.
