Manchester United boss Sir Alex Ferguson is happy to keep Anders Lindegaard and David De Gea on their toes.

Lindegaard was selected against Wigan and though De Gea may return tomorrow, the odds must be against the former Atletico Madrid man retaining his place for Sunday's crucial trip to Liverpool, where he was blamed for United's FA Cup exit last term.

"The most important thing I'm trying to achieve is experience of the English game," said Ferguson.

"They are both young and don't have the experience of an Edwin van der Sar or Peter Schmeichel so alternating is not a problem for me.

"That's the policy I have been adopting and I'm comfortable with it."
