Mesut Ozil is in contention to return to the Arsenal team for Monday's Premier League clash with West Brom.
The Germany midfielder has been struggling with a knee injury but is now back in training, while Theo Walcott should be fit despite being forced off with a knock in the midweek Carabao Cup win over Doncaster.
Danny Welbeck (groin), Francis Coquelin (hamstring) and Santi Cazorla (ankle) are missing, as is Calum Chambers who has suffered a recurrence of a recent hip problem.
West Brom midfielder Gareth Barry is expected to break the Premier League appearance record against Arsenal at the Emirates Stadium.
The 36-year-old, who made his professional debut for Aston Villa in 1998, will play in his 633rd top-flight game and break Ryan Giggs' record if he features on Monday night.
Chris Brunt (calf) will be assessed along with Nacer Chadli (thigh) and Oliver Burke (hamstring) while it remains to be seen if Jake Livermore will return to the squad after being given a break by Baggies boss Tony Pulis.
Arsenal squad: Cech, Ospina, Mertesacker, Holding, Koscielny, Monreal, Mustafi, Bellerin, Nelson, Kolasinac, Ramsey, Wilshere, Xhaka, Elneny, Ozil, Giroud, Walcott, Sanchez, Iwobi, Lacazette.
West Brom squad: Foster, Myhill, Nyom, Evans, Dawson, McAuley, Yuning, Hegazi, Gibbs, Brunt, Yacob, Morrison, Field, McClean, Chadli, Barry, Rondon, Rodriguez, Burke, Robson-Kanu, Krychowiak, Livermore.
