Arsenal have been rocked by a centre-back crisis ahead of Saturday’s trip to Brighton - with Pablo Mari expected to miss the remainder of the season.
The Spanish defender was injured during the first half of Wednesday night’s 3-0 defeat at Manchester City and is expected to be out for several weeks with damaged ankle ligaments.
Arsenal fear the injury means Mari will not play again before the end of the campaign and his absence leaves Mikel Arteta desperately short of options in the centre of his defence.
