Arsenal will be without Olivier Giroud for Friday night's Premier League visit of Liverpool.
The striker was forced off in Tuesday's Carabao Cup quarter-final win over West Ham with a hamstring injury and is likely to miss the majority of Arsenal's festive fixtures.
Francis Coquelin also hobbled out of that game but could still be in contention but Aaron Ramsey (hamstring) is missing, as is long-term absentee Santi Cazorla (ankle). Wenger should be able to call on defender Shkodran Mustafi following a thigh injury.
Liverpool striker Daniel Sturridge (hamstring and illness) and defender Joel Matip (adductor) remain doubtful for the visitors.
Alberto Moreno is still sidelined by his ankle problem, but Emre Can is available again after sitting out last weekend's 4-0 win at Bournemouth as he served a suspension.
Adam Lallana is set to be involved again after coming off the bench at the Vitality Stadium for his second appearance of the season.
Arsenal squad: Cech, Ospina, Mertesacker, Holding, Mustafi, Koscielny, Chambers, Monreal, Debuchy, Bellerin, Nelson, Kolasinac, Maitland-Niles, Coquelin, Wilshere, Xhaka, Elneny, Ozil, Iwobi, Sanchez, Welbeck, Walcott, Lacazette.
