Arsenal are missing the suspended Granit Xhaka for Saturday's Premier League clash with Middlesbrough at the Emirates Stadium.
Santi Cazorla is a doubt after taking a kick against Ludogorets on Wednesday, but the Gunners otherwise have no fresh injury concerns.
Olivier Giroud (toe), Aaron Ramsey (hamstring), Per Mertesacker and Danny Welbeck (both knee) are still missing.
Provisional squad: Cech, Ospina, Debuchy, Bellerin, Holding, Gabriel, Koscielny, Mustafi, Gibbs, Monreal, Elneny, Coquelin, Cazorla, Oxlade-Chamberlain, Ozil, Sanchez, Walcott, Iwobi, Lucas, Akpom.
