Andre Villas-Boas: "Obviously it is going to be debated and debated and I hope it doesn't mar the game. During the game we got most of the decisions against us. I prefer to look at this game on my view and United prefer to look at it on their view.
"We take our boost of confidence and the debate is going to be whether it was a penalty because that is controversy and it sells better but we shouldn't mar the game and the quality of the game played in these difficult conditions.
" Fortunately we got a point, I think it is credit for the game that we had. We were the best team and created the best chances. I think it was probably the worst United game in terms of opportunities, with them having only four. It is a pity we couldn't win but I'm extremely happy with the draw obviously."
Sir Alex Ferguson: "It was a clear penalty. It was definitely a penalty. He has put his leg right in there. The linesman (Simon Beck) is facing it, I thought he had a very poor game, the linesman.
"I thought he was disappointing. We have got that history with him. He never gave offside with (Chelsea striker Didier) Drogba at Old Trafford when he was three yards offside. Everyone remembers that, I certainly do. For me it was a poor performance from him, why he never gave a penalty I don't know.
"I think he had a shocking game, he's had a bad game and we never got anything from that side of the pitch."
Rafael Benitez: "We have been doing well and creating chances in all our games. In the games we didn't win we deserved to win. It was just a matter of time until we had a performance like this.
"We could spend half an hour talking about incidents in the game, but we deserved to win against a good team.
"In the second half, we didn't have too many options. We changed players trying to bring on fresh legs, but it was still very close. We did a fantastic job. We had to stick together at the end and try to defend."
Arsene Wenger: "The referee gave a lot of free-kicks and some much less than the (Francis) Coquelin one. It's frustrating.
"It doesn't mean we should have conceded the goal but, in the big games, these decisions have big implications.
"He could have (sent off Wojciech Szczesny and) given Ramires a yellow card as well."
