Both injured in November, Francis Coquelin and Santi Cazorla were ruled out for a number of months.

Knee injuries suffered in games against West Brom (Coquelin) and Norwich (Cazorla) have left the Gunners incredibly thin in midfield, with Aaron Ramsey and Mathieu Flamini the only established midfielders to still be fit. Calum Chambers played there against AFC Bournemouth but isn’t a proven option.

Last week, updates from Arsène Wenger were misintepreted, with some fans and outlets reporting that Cazorla could be back in February.

“Nothing’s changed [from the original timescale] with Santi,” Wenger told as he gave the latest team news before the Gunners’ FA Cup game against Sunderland. “It could be a bit shorter with him because he’s often quicker [to recover] than you expect him to be. Cazorla and Coquelin are doing well.”
Coquelin is supposedly running again, so could return to action within a month or so, as was originally predicted.
The Gunners have coped well without the duo, and the imminent signing of Mohamed Elneny will ease worries further. Wenger’s men are proving that the midfield which started the season is not the only viable option, but that doesn’t mean the boss won’t be glad to have both players back.
But, especially in the case of Cazorla, don’t hold your breath and expect him back in the next couple of weeks.
