Doubts remain over Arsenal striker
Pierre-Emerick Aubameyang joined Alexandre Lacazette in Thursday's training session but he could miss Arsenal's trip to Bournemouth.
Lacazette is likely to be in contention for the Cherries clash, but concerns remain over Gunners top scorer Aubameyang.
The ex-Borussia Dortmund star pulled out of Gabon's AFCON qualifying tie during the international break because of a back problem and he may not be risked for the match at the Vitality Stadium on Sunday.
Lacazette also withdrew from France's squad because of a groin complaint but the ex-Lyon star appears to be on course to keep his place in Unai Emery's line-up.
Konstantinos Mavropanos is currently recovering from a groin injury and is expected to return to training this month.
Stephan Lichtsteiner and Nacho Monreal are both dealing with hamstring complaints and could also miss out.
Laurent Koscielny is currently being integrated back into training after his Achilles injury.
