The Dane moved to United in January from Aalesunds.
Lindegaard told manutd.com: "When you come from a small side in Norway you can't prepare yourself for how big Manchester United is. But on the other hand it has the same mechanisms as any other club - people talk about the same things, they interact in the same way. There's nothing different in that respect - it's just that this club is a million times bigger.
"I'm enjoying my time in Manchester very much - more and more with each day that passes, actually. I'm a happy human being at the moment and that's what life is all about."
