The former Everton man was taken off the field on a stretcher after colliding with Liverpool's Jordan Henderson and was later ruled to have suffered a concussion, which will keep him out of action for at least a week.

Wenger also revealed that the Gunners will be missing Abou Diaby and Yossi Benayoun, while Tomas Rosicky is doubtful for Tuesday's match, which sees Arsenal enter with a 4-0 deficit from the first leg in Milan.
