Arsene Wenger concerned by Abou Diaby injury

Arsenal manager Arsene Wenger today revealed his concern over Abou Diaby's ankle injury, admitting he is not sure when the midfielder will be able to play again.

The 24-year-old has been out of action since October 16 after failing to fully recover from the effects of a crunching challenge by Bolton defender Paul Robinson the previous month.

Diaby suffered a broken leg and a dislocated ankle against Sunderland in May 2006, but returned to become a key member of Wenger's side.

However, Wenger feels the France international could be set for another long spell on the sidelines.

"You look at Diaby since he got this tackle (from Robinson), he has never come back to a normal level," Wenger said.

"He was never himself and today we have worries for him. We don't know how long he will be out.

"He has seen two surgeons already and at the moment we have to be patient to see if he can get away with it."
