Arsenal have been handed a further defensive blow with the news that Sokratis Papastathopoulos is set to be on the sidelines for up to four weeks.
The Greece international fell awkwardly on his ankle while competing for a ball against Jesse Lingard during the Gunners' FA Cup defeat to Manchester United on Friday.
The Gunners confirmed that the centre-back will be out of action until the end of February at least, when he is expected to return to training.
Laurent Koscielny also sustained an injury in the match against United when Romelu Lukaku’s foot collided with his head, ruling him out with a suspected broken jaw.
