Manchester United boss Ole Gunnar Solskjaer detailed his tactical approach for victory over Manchester City.
City had over 70 per cent possession on Sunday, but still ended up losing 2-0.
Solskjaer explained: "At times, we pressed and pushed them back and we tried to be aggressive with the wing-backs and three up front. So we ended up with three at the back, and, when we hit the press, I think we made them make mistakes and, of course, we're happy with the result. I can't put my finger on anything, but, at times, you'd like to defend with the ball sometimes but I'm not going to complain.
"Anthony [Martial] and Bruno [Fernandes] have hit it off but Bruno is that type of player. Of course, we've got set routines and I've seen them do it before. We're going to improve as a team, they're going to improve as players, because, you know, there were two or three times today, head up and we score goals. Twice Dan James could just square it, once for Bruno, one for Anthony. Anthony should square it for Bruno. Those little things they'll come, but it's a privilege because they want to learn as well and they listen to the advice we give them."
