Arsenal are facing a midfield injury crisis with Mikel Arteta and Aaron Ramsey now expected to be sidelined for a month, missing out on tonight's Champions League group stage clash with Galatasaray.
Jack Wilshere will be in tonight's squad for the must-win Group D game, but Abou Diaby is likely to miss out with a hip problem.
Defender Matheiu Debuchy is a long term absentee, along with Theo Walcott and Olivier Giroud.
Manager Arsene Wenger has previously spoken of the importance of winning home games in the Champions League so the pressure is on the Gunners to get off to the perfect start after the disappointment in Dortmund, when they suffered a 2-0 defeat.
Arsenal vs Galatasaray is on Sky Sports 5HD from 6pm, kick off at 7.45pm
