Arsenal manager Arsene Wenger has confirmed that Francis Coquelin has returned to training, but he is unsure whether to throw the midfielder into action against Olympiacos on Tuesday.

The Frenchman has been absent from the Gunners' last two matches due to a knee injury.

Wenger hinted at the weekend that Coquelin would play in the Champions League clash at the Emirates, but today, he told reporters that "we will see".

Arsenal suffered defeat in their opening Champions League game against Dinamo Zagreb earlier this month.
