Owen Hargreaves admits Manchester United is "bigger than" he expected.
"It's bigger than I anticipated, and better organised than Bayern. There's more attention to detail, and there's a lot more banter in the dressing room.
"We play music before a game, which is something you'd never do in Germany.
The softer side of Sir Alex Ferguson has also taken him by surprise. "He's been fabulous," says Hargreaves.
"One of the first times I saw him he just came over, put his arm around me and asked me how I was doing. I don't think I'd ever had a manager do that to me in my life."
