Sir Alex Ferguson has admitted his disappointment with Wayne Rooney who played for England in midweek despite a niggling knee problem.
The 24-year-old might miss out against Wolves at Molineux in the Premier League and Ferguson has suggested the former Everton youngster will only have himself to blame.
The Scot 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 can't believe it."
Rooney played 86 minutes in the 3-1 win over Egypt before being replaced by Carlton Cole after feeling his knee during the Carling Cup final win over Aston Villa.
