Liverpool manager Jurgen Klopp: "It's very frustrating. We can't say much about real things in the game as we lost. We had more chances, more of everything but we have nothing. That's what we have to realise. That's because of a set-play.
"It's frustrating. It's a short corner, we have to defend it better. Usually we should try avoid the cross but in the end, the body contact came too late. Fellaini went the way he went, then that's how it is after hitting the crossbar. Rooney is free and used his chance, we didn't use ours."
Manchester United manager Louis van Gaal: "To beat Liverpool is always important and today it was important because our competitors have lost points and when the gap is like this you can oversee the points gap.
"We started 2015 very good with a lot of wins and we didn't lose. This game is a big boost to the players, to the fans, to everybody. We have to continue of course and we can do it because we show every week that we can do it.
"I have to admit that we survived the first half because Liverpool were more aggressive, we could not get the ball and we did not create anything. In the second half we came into the match and we created two chances and scored from one of them."
