Arsenal manager Arsene Wenger has suggested that his players have lost belief in themselves.
The Gunners lost 2-1 to Manchester United at Old Trafford on Saturday in the Premier League to slip down to seventh in the table.
"At the moment they have forgotten how good they are," he said. "I believe that if you look at our overall performance we are indeed good, we are still the best defence in the league.
"If you look at the goals conceded, I believe at the moment we don't have to focus too much on that.
"Our game is about creating chances, about going forward, about having an offensive drive. What is most important is that we play again with our enthusiasm, desire to create chances and enjoy our game, more than about 'do we concede a goal or not'."
Arsenal are away at Schalke in the Champions League on Tuesday.
