Mikel Arteta will undergo a fitness test as Arsenal get set to take on Olympiakos in the Champions League this week.
The Spanish midfielder has an ankle problem and may still miss the Gunners' home clash with the Greek club tomorrow night where he could join Abou Diaby and Wojciech Szczesny in the treatment room.
"Arteta will have a test tomorrow on an ankle injury. Diaby is out with a thigh injury. Szczesny will be two or three weeks still," manager Arsene Wenger confirmed in his press conference.
Arsenal beat Montpellier 2-1 in France in their Group B opener two weeks ago whilst Olympiakos lost their home fixture 2-1 to German club Schalke.
