Arsenal fear Mathieu Debuchy is facing three months out with his ankle ligament injury.
The Mirror says Debuchy is facing three months out to plunge Arsenal into a defensive injury crisis.
Arsene Wenger fears Debuchy will be missing until Christmas after suffering significant ligament damage when he sprained his ankle during Saturday's draw with Manchester City.
It means the Gunners are now desperately short of cover in defence as Chambers was also the only back-up for centre-halves Per Mertesacker and Laurent Koscielny.
