Gunners face anxious wait on Oxlade-Chamberlain

Arsenal face an anxious wait to find out the extent of the hamstring injury to England midfielder Alex Oxlade-Chamberlain.

The 21-year-old, who had just returned to the side following a groin problem, was substituted during the second half of Monday night’s FA Cup quarter-final win at Manchester United, where he had earlier set up Nacho Monreal’s opening goal.
