Arsenal have been left sweating over Francis Coquelin after he picked up a knee injury in today’s 2-0 defeat to Chelsea.

On 21 minutes the midfielder landed awkwardly after challenging for a header, his knee bending backwards. Although he continued until half-time, he was sacrificed at the break for Calum Chambers so Arsenal could get a defender on in the wake of Gabriel’s red card.

After the game Arsene Wenger confirmed that Coquelin had picked up a problem that would more than likely keep him out of the midweek Capital One Cup clash with Sp*rs.

“It is a little knee injury, ” said Wenger. “I don’t know how long it will be … certainly not for midweek … I don’t know yet how long.”

Fingers crossed it’s nothing too serious.
