Arsenal will be without injured duo Theo Walcott and Aaron Ramsey for Saturday's Premier League visit of Newcastle.
Ramsey injured his hamstring in last weekend's 1-1 draw at Southampton while Walcott (groin) is also sidelined, although the Gunners could welcome back Shkodran Mustafi as the defender could return following a thigh complaint.
Boss Arsene Wenger said: "Mustafi is back in training today. I don’t know if I will include him tomorrow, it’s still a little gamble and apart from that we will have to see how everybody recovers. We’ll see today in training, but we have no basic problem.
"Of course Aaron Ramsey will not be available, I said that he will be out for a little longer and that will be maybe three weeks that he is not in contention.
"He [Walcott] had a little groin problem. He would have been in the squad at West Ham. He will not be available tomorrow I think as well."
Wenger is likely to bring Sead Kolasinac and Alexandre Lacazette back into his starting line-up after they were rested at West Ham, but Santi Cazorla (ankle) remains absent.
Provisional squad: Cech, Ospina, Mertesacker, Holding, Mustafi, Koscielny, Chambers, Monreal, Debuchy, Bellerin, Nelson, Kolasinac, Maitland-Niles, Wilshere, Xhaka, Elneny, Ozil, Iwobi, Sanchez, Welbeck, Lacazette, Giroud.
