Arsenal will learn later on Wednesday the extent of Mesut Ozil’s hamstring injury, amid predictions that the Germany midfielder could be out for up to a month.

Ozil came off at half-time in the midweek Champions League draw at Bayern Munich — a result that knocked them out of the competition — and Arsenal manager Arsene Wenger admitted he fears the worst.

“He has a hamstring problem that looks quite serious,” Wenger said.

“For sure he’s out [of Sunday’s match against Tottenham]. We have to make a scan to see how bad it is, but he’s out for at least a few weeks. I hope it’s not too bad.”
