The Dane has surrendered the No1 spot at United to David De Gea after another injury setback.
"It is frustrating that I have been stopped due to injury. It was not so serious as last time, but no less annoying," Lindegaard told dr.dk.
"The ankle has not been properly fit before now. I have had problems after I tore some ligaments and I have not been able to kick properly in 9-10 months. It is only starting to be good now."
