Manchester United boss Sir Alex Ferguson feels Wayne Rooney is at fault for the knee injury which could rule him out of Saturday’s Premier League trip to Wolverhampton Wanderers (Wolves 9/1, United 3/10, draw 4/1 ).

The Red Devils chief was unhappy that the 24-year-old striker agreed to play for England in Wednesday’s 3-1 international frienly win against Egypt at Wembley, despite carrying a slight knee problem following last Sunday’s Carling Cup final victory against Aston Villa.

Following his 86-minute run-out for the Three Lions, top scorer Rooney (3/10 @Totesport) is a doubt for United’s trip to Molineux and Ferguson feels his player was at fault rather than England coach Fabio capello.

“I don’t think he should have played,” he said.

“It is his own enthusiasm that has caused it. His problem is that he can’t say no.

“He told us on Sunday he was feeling his knee. Then all of a sudden people put an arm around his shoulder with England and he wants to play.

“Fabio Capello has to pick his best team. A win was important so I don’t blame him at all.

“I was more disappointed with Wayne. Why didn’t he come off? I cant believe it.”
