Arsenal could again be without Mesut Ozil when they welcome Fulham to Emirates Stadium on Tuesday.
Ozil missed the thumping defeat to Liverpool with a knee injury picked up ahead of the trip to Anfield.
When asked if the injury is serious, Arsenal coach Unai Emery said: "[It's] His knee. I don’t know if it’s big or not big, but it’s his knee."
Meanwhile, the Gunners are still facing a defensive injury crisis with Hector Bellerin (calf), Konstantinos Mavropanos (groin) and Rob Holding (knee) all definitely out.
Shkodran Mustafi returned for the defeat at Liverpool but was withdrawn at half-time after the Gunners shipped four goals in the first period, while Nacho Monreal (thigh) remains a doubt,
Further up the field, Henrikh Mkhitaryan is out for six weeks with a broken metatarsal, Emile Smith Rowe (groin) remains out, while Danny Welbeck (ankle) is a long-term absentee.
