Mathieu Debuchy set to miss at least 2 months with ankle injury

Arsenal look set to be without defender Mathieu Debuchy for at least two months. The French international -- who joined the Gunners from Newcastle United this summer -- sustained an ankle injury in Arsenal's 2-2 draw with Manchester City on the weekend, and initial assessments suggest he could be on the sidelines until November at the least.

It's a worrying injury for Arsène Wenger, who failed to significantly beef up his wafer-thin defence in the summer transfer window. Debuchy arrived as a like-for-like replacement for the outgoing right-back Bacary Sagna, and though Calum Chambers arrived from Southampton, he's so far been used at centre-back. Other than Chambers, the Gunners have no cover for the starting central defensive pair Per Mertesacker and Laurent Koscielny.
