Arsenal midfielder Jack Wilshere is out three weeks with an ankle injury and will miss England's World Cup qualifiers against San Marino and Montenegro this month. The injury also rules the 21-year-old out of Arsenal's Champions League tie against Bayern Munich on Wednesday.

"He has an inflamed ankle, the other ankle to the one he injured [before]," Gunners boss Arsene Wenger said.

"He has some bone bruising. The last time it deteriorated into a stress fracture. That's what we don't want to happen.

"We trust people who are specialists in this area.

"He was out for 17 months and we had to deal with it. We must be able to deal with it for two or three games."
