Arsenal only has one new injury worry after its game against Chelsea at the Emirates Stadium, with Abou Diaby (thigh) being withdrawn in the first half, and he will be joined on the sidelines by Tomas Rosicky (Achilles) and Bacary Sagna (foot).

Jack Wilshere made his long-awaited return to football on Monday in the Under-21 game against West Brom, but won't feature in the game. Emmanuel Frimpong also made an appearance against the Baggies following his cameo role in the League Cup, but is still short on fitness.

Olympiakos is set to name Roy Carroll in goal, as the keeper makes a return to the shores of England following spells with Manchester United and West Ham.
