Arsenal's injury problems in defence have gone from bad to worse after Cristhian Mosquera came off in the first half of their game with Brentford on Wednesday night.

The Gunners headed into the match without their first-choice defensive pairing of Gabriel and William Saliba. Mosquera and Piero Hincapie have deputised in their absence - but the former could now be about to join them on the sidelines.

Mosquera, 21, was seen struggling just before the half-time interval. And he was swiftly withdrawn for Jurrien Timber, though the severity of the issue that led to him coming off remains to be seen.
