Now a free agent, Hangeland is expected to sign for QPR.
"He is very difficult to work with. He has a reputation of being a very strict manager, which he is," said Hangeland on Sky Sports News.
"I think his main tool is to try and mentally and physically batter his players and then hopefully get some results out of that.
"Is that a right fit for English football? I don't think so personally, I thought rather than help us try and avoid relegation, I think he made things worse and harder for us.
"I hope I'm wrong because I really love the club, but in a word no, I don't think he is the right man.
"I think things will get worse before they get better and I really think that what's happening now at the top of Fulham is very disconnected, and very far from the Fulham that I know and from the Fulham fans."
