Arsenal manager Arsene Wenger has revealed that Kieran Gibbs will miss tomorrow night's Champions League last-16 decider with Bayern Munich, after picking up a new ankle injury against Everton last weekend.
Gibbs was substituted with just two minutes left in Saturday's FA Cup quarter-final and went straight down the tunnel with an ankle knock, failing to recover in time to make the trip to Germany less than 48 hours later.
Wenger has revealed that the England left-back is also struggling to recover in time for Sunday's North London derby, which will mean either Thomas Vermaelen could be drafted in to deputise at the Allianz Arena.
He told reporters at a pre-match press conference for the Bayern clash: "We lost Gibbs (from last weekend). He has a chance to play Sunday.
"Koscielny is back in the squad. Vermaelen has a chance to play at left-back."
Vermaelen made a rare start in central defence last weekend with Kosicleny nursing a hamstring injury, but the French international should be fit to return from the outset against Bayern.
With Nacho Monreal also still sidelined Wenger could go with Vermaelen, Carl Jenkinson or even Mathieu Flamini as an emergency left-back against Bayern, who will have Arjen Robben and Franck Ribery looking to take advantage of any indecision on the flanks.
Robben was in particular magnificent in a 2-0 first leg victory for Bayern at the Emirates, which has left with the Gunners facing an uphill task to keep their European dream alive this season.
