Arsenal boss Arsene Wenger admits Abou Diaby suffered another injury setback in victory at Liverpool.

The stunning 2-1 win marked Diaby's comeback game.

Wenger told arsenal.com: "The bad news of the day is that Diaby is injured and did his hamstring. Benayoun has a small hamstring problem, Gibbs has a problem. We look decimated after the game. I don't know who will be available on Tuesday night. Maybe I will play with six strikers as we have to score goals!"
