One in one out for Gunners

Arsenal will be without Wojciech Szczesny for tonight's Champions League clash against Montpellier but Abou Diaby could return.

Szczesny picked up an ankle injury in Saturday's 6-1 victory over Southampton so will miss out but Arsene Wenger will have no qualms about replacing him with Italian stopper Vito Mannone.
Midfielder Diaby has been struggling with a hip problem but was included in Wenger's 18-man squad that left for France but both Andrey Arshavin and Marouane Chamakh have been left out.
Jack Wilshere (ankle) and Emmanuel Frimpong (knee) are back in training but the game comes too soon, while Tomas Rosicky is also missing with a hamstring problem.
