Manchester United face an early season injury crisis.

Wayne Rooney and Michael Carrick are doubts with a virus.

Owen Hargreaves, Nani, Anderson, Cristiano Ronaldo and Park Ji Sung are crocked, while Louis Saha has been out since March and Gary Neville has calf problems.

Boss Alex Ferguson said: "You worry about having a team ready for the start of the season. I doubt if we'll have Wayne fit for the start.

"It's a virus we believe he picked up in Nigeria. It's not a nice one. It's such a bad virus that he's not been training since we got back from Africa on July 28.

"The league season starts in 12 days' time and he's gone a long time without training.

"Carrick also had the virus but, hopefully, he'll play some part against Portsmouth in the Community Shield on Sunday."
