Arsenal will be without Hector Bellerin for their FA Cup fourth-round meeting with Manchester United after the full-back was ruled out for up to nine months with a knee injury.
The Gunners host Ole Gunnar Solskjaer's in-form United with head coach Unai Emery suggesting he may make changes to his side.
Konstantinos Mavropanos is pushing for a first start of the campaign and Petr Cech will be keen to play in goal, while Bellerin joins former United pair Henrikh Mkhitaryan and Danny Welbeck (both ankle) and Rob Holding (knee) on the injury list.
Provisional squad: Leno, Cech, Martinez, Jenkinson, Lichtsteiner, Koscielny, Papastathopoulos, Mustafi, Mavropanos, Kolasinac, Monreal, Maitland-Niles, Xhaka, Elneny, Torreira, Guendouzi, Ramsey, Iwobi, Ozil, Lacazette, Aubameyang, Nketiah.
