Former Arsenal star Gilberto Silva believes that Mesut Ozil needs to show improvement at the Emirates following an inconsistent 18 months at the club.
The German World Cup winner has struggled to recreate his form from Real Madrid following his £42m move to the Gunners in the summer of 2013.
"Coming from Spain it is tough to adapt, it doesn't always happen straight away," The Mirror quotes Silva as saying.
"I think the most important thing is that the player understands the philosophy of the team, the philosophy of the manager and the expectation from the fans.
"I do really like him as a player but sometimes in the game he does look quite slow, although he has that quality to change the game. He can be more decisive for Arsenal for the quality he has, he can be much more decisive for the club."
Ozil has also been hampered by injuries during his time at the Premier League club.
