Arsenal boss Arsene Wenger admits midfielder Tomas Rosicky is still struggling with injury.

"He is not close to playing again and he has not had any real setback, but the evolution [of his injury] is very slow," Wenger told the club's official website.

"The recovery process is slower than we expected at the start. It doesn't look worrying but the delay is longer than expected.

"He had a re-attached tendon that was loose in his hamstring, and that demands a lot of time to re-coordinate the movements of the hamstring. That makes it very difficult to predict exactly one week more or less how much time it will take.

"But I am optimistic that before Christmas you will see him in a good shape."
