It's time to wrap this up. A day that will live long in the memory of Southampton fans. The Saints are up to third in the Premier League table after a first league away win at Manchester United for 27 years. But it's back to the drawing board for Louis van Gaal and his Red Devils.

Thanks for your company and all your comments. The football does not stop here. Build up to Barcelona's game with Atletico Madrid is under way, while David Moyes's Real Sociedad are currently 1-0 up at Granada. Score updates here. Until later...

Manchester United's next game is away to QPR on 17 January where they face a reunion with Rio Ferdinand. After that their next Premier League match is at home against bottom club Leicester on 31 January.

Southampton are in FA Cup action next. They face a third round replay away to Ipswich on Wednesday before travelling to Newcastle on 17 January.

Andi in Aylesbury: All I keep reading is spend more money on Man Utd defence to get it better. What happened to training and getting the best out of what you've got. Isn't that what great managers do.

Ginger in London: Great performance from the Saints. Everybody in the media was talking as if they were a relegated side even before the season started. Not any more.

A tense exchange in the post-match news conference between Louis van Gaal and a journalist, who informs the Dutchman that he has the same amount of points as David Moyes did at the same stage last season.

"Yes. You have waited until this moment to put this question? This moment I have the same points as David Moyes? OK.

"We have to be better, we have to improve and that is why we are working hard and working on that. I have said already we were the dominating team, but we have to create more when you are the dominating team. I think Southampton came for the draw, and went away with the victory."

More bad news for Manchester United. Striker Robin van Persie is to have a scan on a damaged ankle that forced him to limp off against Southampton.

Southampton boss Ronald Koeman, speaking to Sky Sports: "We had some problems in the first half. The movements of Wayne Rooney especially but in the second half we were much better, we had more domination and scored a good goal, then you knew they would play long ball with Marouane Fellaini. It is three points at Old Trafford and that is fantastic.

"The win says a lot about our ambition. We showed we can beat big teams. The belief was in the team today and that was key for the three points. It was not an easy game for Southampton, it hasn't been in the past but finally our fans celebrate three points at Old Trafford."

Manchester United manager Louis van Gaal on the absence of Radamel Falcao from his squad: "As a coach you have to make decisions, you have to look at the composition of your team and select and look at your game plan. I decided he is out of the 18 because I have to change Luke Shaw and Angel Di Maria for example. You have to look at the needs of your selection at the time. Marouane Fellaini came in and because of his substitution we created three chances.

"I hope we are improving, because we can still improve. We showed today that we played better at home against Southampton than away, then we won but now we lost. We can still win the FA Cup and reach the top four, we have a lot to fight for."

Manchester United manager Louis van Gaal, speaking to Match of the Day: "We played a much better game than Southampton. They were lucky to score out of nothing. That is very disappointing. We didn't create so much but we dominated the game. They came for a draw, I believe, and they go away with a victory, that is disappointing.

"We have to improve. We have to make better choices with the ball but you also have to take into account that the opponent was well organised today."

Manchester United boss Louis van Gaal, speaking to Sky Sports: "We didn't create so many chances, despite dominating the game. We gave them a chance in the first minute but dominated after that. We had three big chances, but it was not enough.

"Southampton were well organised, defended well but they came for a draw, I believe, and they go away with a win, which is disappointing. Mata had three chances, but you cannot change the result. We gave the goal away. Football is game from mistakes."

Southampton substitute and match winner Dusan Tadic, whose introduction was delayed after leaving his shirt in the dressing room: "The top four is possible but we have to go game by game. We have beaten good opponents and we have to keep doing this. There was no shirt, I'd left it in the dressing room. When you score you don't think about what you will do. Normally I don't do that (take shirt off), but this time I did."

Southampton's Morgan Schneiderlin, speaking to Sky Sports: "We have played well here before and we deserved a win. It's just a fantastic feeling. Character was key, we went through a very tough patch in December and we showed good spirit and showed we believe in ourselves and in each other and that we can do something great this season.

"People were writing us off at the start of the season but we will take things game by game and see where we are at the end of the season. We must not get carried away."

Ronald Koeman has moved on from his television interviews and is now doing a press conference for the national media. We'll bring you the best of that in a few minutes.

Tom Blakey:, external Seven points against Chelsea, Arsenal and Man Utd is top-four form. Time to start taking Southampton seriously!

Sean Haughton:, external If Southampton, Arsenal and Spurs kick-on, Manchester United will be looking at seventh again come May. So much for that game-changing war chest.

David Broome:, external Maybe Louis van Gaal will come back down to earth and worry about top four finish rather than the title? Phil Jones is the clumsiest player in the Premier League.

Southampton boss Ronald Koeman, speaking to Match of the Day: "Juan Mata had two big chances at the end, we missed that luck in the home game and we got that today. If you play against a big side you need spirit and quality but you also need belief in yourself and your team-mates and we showed that today. We have had good organisation all season, we have 11 clean sheets in 21 games and that is key to being successful.

"We have aspirations [of securing a European finish], but at the beginning of the season you have to wait. Now we can say we fight for a European place. The top five or six, we will fight until the last game."

On goalscorer Dusan Tadic: "I don't like players taking off their shirt. It is a yellow card but he was fantastic in the final half hour. He made the difference when he came in and I am proud of him."

Manchester United forward Wayne Rooney, speaking to Sky Sports: "That is football, that is how it goes. I think overall we had the better chances and played the better football and deserved to win but we were punished. I have seen Southampton play better, we stopped a lot of their threats but we got punished. We have to move on and focus on the next game."

"United's back three can't defend. They keep making errors and I've got no idea how they keep getting in the team. Phil Jones and Chris Smalling have both been there long enough to grab that position by the scruff of the neck, so I can't understand why they haven't.

"Going forward today they were also awful. Not one shot on target and I wonder when the last time was that happened in the history of this ground."

Ronald Koeman has just told the television cameras that Southampton dominated at Old Trafford. Now Dutch compatriot Louis van Gaal is claiming United dominated. The truth is United only really came to life in the closing stages yet they still failed to register a shot on target.
