The Gunners boss conceded losing Laurent Koscielny and Gabriel for the FA Cup final against Chelsea was "a big blow" for his side
Arsenal manager Arsene Wenger is facing a defensive crisis ahead of the FA Cup final with Laurent Koscielny and Gabriel set to miss out against Chelsea.
Koscielny was shown a straight red card for a wild lunge on Enner Valencia in the early stages of Sunday's 3-1 victory over Everton, a result that did not prove enough to secure Champions League qualification as both Manchester City and Liverpool won to consign the Gunners to fifth.
