There could be an appearance at some point for Chuba Akpom, who has been given a Champions League squad number by Arsene Wenger, but it is likely he will be on the bench at best. One Gunner who definitely will not be playing is Emmanuel Frimpong, who has joined Charlton on loan.
Elsewhere, Abou Diaby (thigh), Lukasz Fabianski (ankle), Gervinho (ankle), Kieran Gibbs (hip) and Tomas Rosicky (Achilles) are all still missing, but Wojciech Szczesny is likely to start again after making his comeback in the north London derby, as did Alex Oxlade-Chamberlain, who should start from the bench.
Montpellier is likely to make a couple of changes after a 1-1 draw against Valenciennes at the weekend, with Younes Belhanda missing the clash in Ligue 1 due to suspension. The midfielder is likely to come back into the side in the center of the field.
