Laurent Koscielny: Good to Go

Koscielny returned from a head injury to start and play all 90 minutes of Arsenal's 2-2 draw with Manchester City on Saturday.

Analysis:

Arsenal have failed to keep a clean sheet this season with Koscielny on the pitch, but he'll get a decent chance Saturday against Aston Villa if he can make it through Tuesday's Champions League match against Borussia Dortmund unscathed.
