Arsenal midfielder Abou Diaby has suffered a setback on his return from injury.

Manager Arsene Wenger has revealed that the 25-year-old suffered a thigh strain after he had made his first appearance of the season against Borussia Dortmund last week.

The French international had been sidelined since the summer after he underwent ankle surgery.

"He is currently not fine. He has made so much effort to get back," Wenger told L'Equipe.

"I was afraid he would never be back to his best, but now I am convinced he will find his full potential again."

The Gunners, who have already qualified for the next stage of the competition, travel to Olympiakos in the Champions League on Tuesday.
