Arsene Wenger has said that Mesut Ozil will need time to adjust to playing in the Premier League.
The German international became Arsenal's record signing when he moved from Real Madrid earlier this month, costing the Gunners £42.5m.
Speaking at his pre-match press conference, the manager said: "He has integrated well, and been well accepted, I think he is not at the top physically yet.
"Overall we are very pleased to have him with us, but he will demand a bit of time to adjust to the vigorous body challenges he will face here in the Premier League.
"He is 24, he has over 50 caps for Germany, and when you play for Germany, you are under a lot of pressure. He won the championship with Real Madrid, and that is a club where there is a lot of pressure."
Arsenal host Stoke City on Sunday.
