Manchester United boss Louis van Gaal knows fans are unhappy with their playing style.

Fans expressed their discontent after their team's 0-0 Champions League home draw with PSV on Wednesday, with boos greeting the final whistle.

“Of course [you want to please the fans] because the fans have to be happy," said Van Gaal. “You are playing for the fans, so you cannot deny that.

“But also you have to see how our opponents are playing against us, and when you see how they play, you know the difficulty of organising against that type of opponent.

“We are still not lucky in finishing the chances. We are creating chances, and when we are not creating, then maybe I am worried. But we are not giving much away. That is why we are second in the league and second in our Champions League group.

“I think that our defensive organisation is normally the best part of our game and, after that match against Leicester, we are proving that we have very good defensive organisation and we have proved that this season more than ever."
