Sir Alex Ferguson: "It was a brilliant day for (Shinji Kagawa). He is a good finisher. His second goal was composed and intelligent, his last was brilliant. He missed that period of football in October and November that set him back a bit. He is gradually getting his form back but next year he will be far better, you will see a really good player then."
Chris Hughton: "I don't think the scoreline was a fair reflection but it shows the quality of the team they put out in the first place. They punished us when they got the spaces in that final period. They have the type of quality that can hurt you. I am really disappointed. Any team who comes here has to put in a real tough shift because you know they will have the majority of possession. The first goal was a poor one by our standards, but I think the second hurt us perhaps that bit more because we had to open up a little bit; when you do that against United, they have the quality to really hurt you."
Rafael Benitez: "I was really pleased with the performance on the pitch and the atmosphere was really good. It was a great performance. The team, for 75 minutes, were in control, good play, good passes and great opportunities. The (West Brom) keeper (Ben Foster) was man of the match, for me. That means a lot."
Steve Clarke: "Ben (Foster) plays like that week in, week out. He's probably made Roy (Hodgson) happy because he's made himself available for selection and it gives Roy a nice problem. The Peter Odemwingie saga for us is over. It's finished. He's a key member of our squad and he's got a big part to play for the rest of the season."
Michael Laudrup: "There was a lot to be pleased about. Firstly the win and secondly our attitude. I spoke in the week about the fact you sometimes see a negative reaction after a big win, but our reaction was an excellent first half where we showed lots of good touches, movement off the ball, and we created chances. We went in at 0-0 but we deserved so much more. After that, Newcastle came into the game and had some very good chances but, like us, they did not score when they were at their best and so that late goal decided the game. It shows our maturity, sometimes with smaller teams when they do well and get recognition from the media you see a reaction in the game after. You can forget every game starts 0-0. I expected what I saw, but I still had to say it as when you win a cup a negative reaction is normal."
Alan Pardew: "We are frustrated and disappointed we did not even get a draw as we more than deserved that. We sat off them for the first 20 minutes of the first half but we sorted that at half-time. In the second half I thought they had settled for a draw, they knew they were doing well to stay in it. But when we did not score in that great period we had you know any mistake can be costly and that is what happened. We missed two or three big chances and you cannot do that at this level. The goal was sloppy, it's a ball into the box, we had four defenders there and it should have been dealt with better; unfortunately it wasn't and it cost us."
Martin O’Neill: "It looked a pretty clear-cut penalty from (Philippe) Senderos handling the ball and the referee has chosen not to give it. I suppose it sounds like a bit of a moan and a bit of a rant but last week (in the 2-1 loss to West Brom) there were two penalty incidents in the game and to me both were penalties given the directives that we have been given by the referees this season. One was given against us and the other one wasn't. The referee chose to miss it and here again. While I agree with the referee that, in general, there are a lot of soft penalties being given, these are the directives we have been given. While 20 years ago maybe the game would have not had a penalty at all, the fact is this is not 20 years ago, it's now, and these are the directives we have been given. I keep mentioning that point because it was the referees who mentioned it, so you can't just turn around and give it and then choose to ignore it when you want."
Martin Jol: "If they had beaten us they would have been on 32 points as well. If you look at Southampton, they are in the bottom four or five - if they had beaten QPR they would have been on 30 points, so everyone can be dragged into a very difficult situation. One one hand, it's a good point and on the other hand, three points would have meant we had done the business but we didn't."
Tony Pulis: "We're disappointed with their goal. Ryan (Shawcross) goes to step in front of him and (Andy) Carroll pulls his shirt and pulls him down. Like I say, we're really, really disappointed that the referee has not given a free-kick there."
Sam Allardyce: "Our misfortune ended up as our good fortune. Our misfortune was Matt Taylor going off with concussion and then straight after that Joe Cole with a hamstring injury. But Ricardo Vaz Te's ball to Jack Collison and (the performances of) those two players throughout the game has helped us win this match."
Mauricio Pochettino: "We've tried very hard. We've put in a great effort to try and get a different kind of result. But because of some mistakes we have made and their goalkeeper's intervention a couple of times we didn't get a positive result."
Harry Redknapp: "I know where the story (about heavy drinking on a trip to Dubai) come from, I know who done the story and they are trying to make problems for the football club. I know exactly where it has come from. It wasn't players. It didn't come from players. I am sure as I can be that it came from a football agent and I know who did it."
David Moyes: "It is noticeable (Nikica Jelavic’s lack of goals) because everyone talks about it. We tend to be as honest as we can and not hide away from anything and at the moment undoubtedly we need Jela to find a way of scoring some goals. He needs to get a goal but I don't know if one goal will make everything right. If I saw him getting four goals in four games then I would start to think `This is what we want'. You have to find a way of making that happen again but we could do with him standing up and getting us some goals now."
Brian McDermott: "We had to make up about 14 points last year and we did that. We have to make up one or two at this time - we think we can do that. We have to keep doing our stuff, keep the spirit going and the group together. We have finished the last three seasons really strongly. If we can do the same this season I'll take that. It would give us a real chance. There is not a lot in the league at all really."
Roberto Martinez: "The first goal showed a real lack of concentration as Downing had a free header in the six-yard box. The first 20 minutes we were very soft and defensively nowhere near where we needed to be. That (first) goal had a snowball effect on our performance. If you look at the stats at the end we had as many shots on target as they had but the performance of Pepe Reina had a bigger effect on the result than us stopping Luis Suarez."
Brendan Rodgers: "[On Luis Suarez]He's such a pleasure to work with. This is a man, and it might seem strange, who not only trains every day and wants to train every day. He is so hungry and has the humility. He is in there pleased for the team. He has quality, finishing, work-rate and that's what makes him world class. [On Coutinho] He is still picking up fitness and got another 60, 70 minutes today. You can see how he fits in to us. But this was a fantastic team performance."
