Arsenal manager Arsene Wenger says midfielder Francis Coquelin has recovered from injury and will be assessed on Tuesday ahead of the Champions League game against Olympiakos.
The Frenchman will soon be joined by fellow midfielders Mathieu Flamini and Mikel Arteta who will be back in the squad next week.
Jack Wilshere and Danny Welbeck continue to be the only two long-term absentees for the Gunners.
"He [Francis Coquelin] has been back since yesterday and I will have to see how he responds to two days of training, but he looks alright," Wenger told reporters.
"Both [Mathieu Flamini and Mikel Arteta] have slight muscular problems, but I think Flamini has a scan today and Arteta certainly as well.
"They are not big injuries. It is a question of days."
