The two clubs meet this week in their Champions League opener.
"Our fans don't need reminding about Galatasaray," he told MUTV.
"I remember our first game there, when we arrived at the airport and there were all these banners, 'Welcome to Hell'.
"Eric Cantona was sent off. Bryan Robson was hit by a policemen's truncheon. It was a nightmare.
"The one good thing about that game is that the atmosphere will be fantastic. The fans will be in the stadium from lunchtime, shouting, singing and bawling. They make such a racket."
