But United boss Sir Alex Ferguson has confirmed that David De Gea should be fit to face Chelsea on Sunday.
Both De Gea and Lindegaard missed United’s 2-0 victory over Stoke City in midweek through injury.
“De Gea should be fit,” said Ferguson. “It looks like Lindegaard will be out for at least four weeks, maybe even five or six. It’s ankle ligaments.
“Ben Amos has been looking for his opportunity for quite a while and we wondered about sending him out of loan. But it’s not easy when you’re in Europe – you need three keepers. He did very well the other night.”
