AS Roma coach Luis Enrique admits his players don't understand his methods.

Enrique has struggled to find consistency with his side, who were beaten 2-1 by AC Milan last week and face a difficult push for Europe.

"The players still don't understand what I want, because football is not mathematics," he said in his press conference.

"I live the match with intensity and if I see a detail that does not convince me, then I get angry. Off the field you notice things that you probably wouldn't from inside it.

"We are not trying to play like Barcelona, as they have characteristics that adapt to their players. The tactical scheme that brings you to victory is to play as close as possible to your opponent's goal."
