Arsenal could have defensive midfielder Francis Coquelin available again following a knee problem.
Mathieu Flamini (hamstring) and captain Mikel Arteta (dead leg) are not available, while forward Olivier Giroud must serve a one-match ban following his red card against Dinamo Zagreb.
David Ospina could again come into goal. Defender Gabriel is available following a domestic suspension but Jack Wilshere (fibula), forward Danny Welbeck and Czech midfielder Tomas Rosicky (both knee) are also sidelined.
The visitors also have a player suspended as Luka Milivojevic is still serving a ban from last season, while Andreas Bouchalakis misses out with a thigh injury and Giannis Maniatis is still working on regaining match fitness following a lengthy absence with a knee problem. Manuel da Costa will need a late fitness test after picking up a calf injury, while Alejandro Dominguez is working to overcome a thigh strain.
