Arsenal's defensive crisis appears to have deepened following reports that Kieran Gibbs is doubtful for this weekend's Premier League meeting with Burnley.
The England left-back is struggling to overcome the damaged hip he suffered during the Gunners' 2-0 win against Sunderland last weekend, The Mirror reports.
Gibbs joins fellow defenders Laurent Koscielny and Mathieu Debuchy on the sidelines, while midfielder Jack Wilshere is said to require a fitness test ahead of the Burnley game.
Hector Bellerin is likely to be drafted into the Gunners' defence this weekend as manager Arsene Wenger is short of alternatives.
