"I think at United we all realise there's a bigger picture. At Bayern, the tension in the team, at times, was probably a bit too much," Hargreaves told the People.
"There were tackles and fights all the time in training because everyone wanted to keep their place. I remember my first season, you can't imagine how many fist fights I had with the older players.
"They felt threatened by me. I wasn't going about my business in a poor way, I was just playing hard and training hard and making myself known. They took offence to that because they could feel me coming through and realised I might take their shirt.
"At United it's not like that. There's no animosity. If you play, you're good enough and you deserve to play - it's not a case of being dropped or anything like that.
Hargreaves added: "I like everything about it here, probably more so than Munich. I prefer the coaching here, it's a bit more personal. In Germany, especially as a young player, I found it difficult.
"I'm a very open person. I'm not the sort that takes the mickey really, I'm respectful. But I was young at Bayern and I admit I was relentless in training and would never give up. Some of the other players thought I was being cheeky and lacked respect. Even some of the coaches thought that too, which I found bizarre. They held me back and felt I was taking too many steps too quickly.
"At Munich, you're expected to know your place. There's definitely a hierarchy and everyone is very conscious of that. It's very difficult for young players to break through in Germany whereas here, if you're good, you're good.
"If you're Wayne Rooney and you're 18, you're in the national team. There are no young and old players, only good and bad players. And I think more than anywhere, here in England that's a true statement."
