Owen Hargreaves admits Manchester United is "bigger than" he expected.
The England midfielder told the Daily Mail: "I've been impressed with everything at Manchester United.
"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.
"I've never known a dressing room that is more together and I think that's down to players like Ryan Giggs, Paul Scholes and Gary Neville. They are very humble. Good guys."
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."
