Arsenal have been dealt a big injury blow after Shkodran Mustafi limped out of Germany's World Cup qualifier against Azerbaijan.
The Gunners defender went off with what looked like a thigh injury and was helped from the pitch by medical staff.
Mustafi was running alongside Ramil Sheydaev when he pulled up, with the Azerbaijan player then twisting and turning past Chelsea's Antonio Rudiger to score a famous goal against the world champions in Kaiserslautern.
He will now likely undergo scans on his return to north London and, dependent on a tear, could potentially miss months of action.
Germany went on to beat Azerbaijan 5-1 and complete their 100 per cent record in qualifying.
