Arsenal manager Arsene Wenger has admitted that his side needs defensive cover ahead of the January transfer window.
The Gunners have suffered a defensive injury crisis this season and may move to sign an extra centre-back next month after the setback to Laurent Koscielny.
Wenger told BBC Sport: "Well, yes with Laurent Koscielny's injury we're a bit cautious and we need cover."
Arsenal are believed to be tracking Ipswich Town defender Tyrone Mings and are reportedly weighing up a move for the 21-year-old in the New Year.
