Arsenal's Theo Walcott ruled out of Manchester United clash with groin injury

Arsenal manager Arsene Wenger has confirmed that Theo Walcott will play no part in tomorrow's Premier League clash against Manchester United at the Emirates due to a groin strain.

The England international was expected to be named in the squad for this weekend's encounter after making his return from a nine-month spell on the sidelines with a knee injury earlier this month.

The 25-year-old came off the bench in Arsenal's 3-0 win over Burnley, but has suffered another injury blow.

Wenger told reporters in this morning's press conference that Walcott will not be available this weekend, while striker Danny Welbeck will face a fitness test today following a hamstring problem.

The Gunners will welcome back Olivier Giroud to the squad after the Frenchman spent three months out of action with a broken foot.
