Arsenal boss Arsene Wenger has revealed that midfielder Francis Coquelin could return for Tuesday's Champions League visit of Olympiacos at the Emirates Stadium.

The Frenchman, 24, sat out this afternoon's 5-2 win at Leicester City after picking up a knee injury in last Saturday's 2-0 defeat at Chelsea.

Mathieu Flamini suffered a hamstring problem in today's victory at the King Power, and Wenger is relieved to have Coquelin back in the nick of time.

"Coquelin could be available for Tuesday," the French manager told Arsenal's official website.

"Today we lost Mathieu Flamini and the only one that could come back is Coquelin and Gabriel is not suspended."

The Gunners lost their Champions League opener at Dinamo Zagreb last week.
