"The one thing that he'll [Lindegaard] have to remember is that United have spent £18million on De Gea, that makes it different.
"He played outstandingly against Benfica, pulling off some really great saves.
"There's nothing wrong with him [Lindegaard] saying he wants to be United's number one. As a manager there's nothing better than having competition for places."
