"This squad doesn't get nervous.
"We thrive on situations when the pressure is really up there and full on.
"The big games - when people are asking questions about us or think we won't do well - we seem to come through it. This is an opportunity to do that again."
He then remembered the last big game United didn't do well in.
"Sitting in the changing rooms after the Celtic match was one of the weirdest feelings ever,"
"There were so many emotions. We were angry, upset and almost baffled in a way - because we controlled the whole game.
"They didn't look like scoring at all. But they get a free-kick, and it was a great one.
"If we had finished off a couple of the chances we had we would have been all right - but we didn't.
"In the Champions League, you must kill games off when you are on top - because the other teams always have that quality and ability to put the ball in the back of the net."
