Lindegaard made two quality saves in the first-half as the teams went into the break with United 1-0 up.
The Dane reflected: "They like to play football, not like kick and rush which I would have expected when I came to the States. It was alright that we won the game but seven-nil is too much.
"It was very noisy. It was difficult to communicate. It seemed to be a great crowd. It must be fantastic for the team here to get that kind of support...that is very impressive.
On his two saves, Lindegaard added: "It's going very quickly so you're just reacting. It's in your backbone what to do. It's not like a process that you go through, you just react."
