Arsenal are unlikely to be able to welcome back any of their injured players when they travel to Premier League leaders Liverpool on Saturday.
Rob Holding (knee), Konstantinos Mavropanos (groin), Hector Bellerin (calf), Henrikh Mkhitaryan (ankle) and Danny Welbeck (ankle) are all out.
Defender Shkodran Mustafi is the only man with a slight chance of being involved but his return from a hamstring problem is not expected to come this weekend, while captain Laurent Koscielny should be fine following a foot issue in the draw at Brighton.
Provisional squad: Leno, Cech, Martinez, Jenkinson, Lichtsteiner, Koscielny, Papastathopoulos, Mustafi, Medley, Maitland-Niles, Xhaka, Elneny, Torreira, Guendouzi, Ramsey, Iwobi, Ozil, Saka, Lacazette, Aubameyang, Nketiah.
