As if Danny Welbeck scoring at Old Trafford wasn't bad enough for Manchester United fans, another one that got away has been at it too.

Paul Pogba produced a stunning winner to increase Juventus's lead over Roma at the top of Serie A to 11 points with victory over Sassuolo.

The former Manchester United midfielder fired the ball home from outside of the box as Juve finally broke through Sassuolo's defence in the 82nd minute.

A reminder that you voted Arsenal midfielder Francis Coquelin as man of the match tonight, the Frenchman won 43.2% of the vote.

"Reading between the lines there, Louis van Gaal sounds like he's really angry with Di Maria. You cannot put your hands on the referee like he did."

"I think he's been an accident waiting to happen Angel Di Maria in the last few weeks. But, how much help has Di Maria had? The manager has picked him, but what kind of support has he had from everyone around the club to look out for him?"

"Momentum works both ways and for United now, they can't win silverware and all they've got left to concentrate on for the rest of the season is a top four finish.

"There's tricky period for them when they still have to play the likes of Chelsea, Man City, as well as Everton.

"It's a massive. massive last two months of the season for them. The results have been OK, but the performances have got to improve."

A stat from Opta here which takes us back to a point we made earlier in the evening:

8 - Only Adebayo Akinfenwa (9 v Liverpool) has conceded more fouls in a 2014-15 FA Cup match than Marouane Fellaini v Arsenal.

Arsenal captain Per Mertesacker: "In the second half there was a feeling we could get something out of it. The crowd got nervous, we were rewarded with the second goal and then we defended from the top in a special way.

"Danny Welbeck was a great player here at United, he's a bit quiet in the dressing room at the moment. I think it hurts him a bit as well as he was here for a long time. We tried to get him going and to tell him he can enjoy special moments with Arsenal."

Manchester United boss Louis van Gaal: "I've said in the dressing room we gave [the game] away by ourselves and that is the biggest disappointment. In the second half, we had the first chance also then we gave it away again.

"We don't lose from the opponent, we lost from ourselves and it was very disappointing. You play this match to win; to beat the opponent, we wanted to be in the semi-final."

"When you have performances like this, as Arsenal you look back and see it as a defining moment. I think the aura of Old Trafford has slipped away now.

"They've lost nine games here in the last two seasons and under Alex Ferguson, that was six seasons worth of defeats."

Manchester United boss Louis van Gaal: "I said in advance that [the top four] is a priority but as a manager, and as a player and club you want to win titles and now we cannot win a title."

The build-up - if you can call it that - to Arsenal's winner is so poor from Manchester United's point of view. Just a goal-kick downfield. Phil Jones fluffs his chest down under minimal pressure, Antonio Valencia gives the ball away under minimal pressure and Danny Welbeck nips in to score.

"Fair play to Danny Welbeck. He was prepared to celebrate. He was born and bred United, but he's changed colours now and he was determined not to see his former team-mates walk out at Wembley in a May final."

Manchester United boss Louis van Gaal on Angel Di Maria's sending off: "In Spain he knows that he doesn't touch the referee, but that is also in his emotion. I've already spoken with him, he knows my opinion but also I have to see on the video.

"I think he's touched the referee and that's forbidden in every country, so he has no excuses."

Cameron Johnson: Reading v Arsenal semi would be good. Last 3 meetings between teams has provided 24 goals including their last cup match at 7-5.

When Manchester United manager Louis van Gaal is asked if there are elements of the performance which are positives, he just laughs.

Full reaction to come...

Danny Welbeck says he never imagined scoring a winning goal against Manchester United. I don't suppose many United fans did either...
