Manchester United boss Sir Alex Ferguson says veteran pair Paul Scholes and Ryan Giggs can go on and on.

"The experience of Ryan and Paul Scholes is going to be very important," said Ferguson.

"Ryan has two years left on his contract and Paul has a similar amount remaining. They will be good years because they have looked after themselves.

"We've got younger players to play alongside them, so the balance is right in that respect. It's difficult to say how long they'll last. But the one thing they have to do is steer clear of injuries. Ryan is in fantastic shape as he's never had a really serious injury.

"In terms of their lifestyles and how they look after themselves, you'd think Ryan and Paul could play on for another couple of years."
