Philippe Coutinho recognises he's been struggling with Bayern Munich.

On-loan from Barcelona, Coutinho has drawn criticism in recent games.

"All games and teams in the Bundesliga are difficult; we always have to fight until the end," he said after victory over Union Berlin.

“Today the team fought until the end. We were calm when we had the ball. We also know that we can improve our game, that is obvious, but today I leave here with good feelings."
