Arsenal v Chelsea - Free £5 bet

Last updated : 01 December 2009 By Footymad

Arsene Wenger's biggest injury concern is William Gallas, who is doubtful after picking up a knock in the midweek Champions League clash with Standard Liege.

Carlo Ancelotti, however, will welcome back Frank Lampard to the midfield, while recently-injured Didier Drogba, Michael Ballack and Deco came through the midweek game with Porto unscathed.
