Premier League - Tevez reveals binge-eating hell
The Argentine was heavily linked with a move away from City and has endured a turbulent relationship with manager Roberto Mancini.
But he claimed he was unfairly portrayed as a disruptive influence in the dressing room, and underwent a "personal crisis" during the summer.
"I'm not the s**t that they say I am," he is quoted as saying in the People.
"I had a personal crisis this summer. I put on five or six kilos and had to check into a clinic. I was depressed and so I ate and ate.
"Only my family and friends know this. People can criticise me if I don't play well, but they can't say 'He missed a penalty so the coach would be sacked.' It's the bad feeling towards me that I can't stand."
Tevez has a poor grasp of English despite playing in the Premier League for five seasons, and he predicted his Argentine compatriot, new signing Sergio 'Kun' Aguero, would face similar difficulties.
"Kun is studying English," said Tevez. "I would say give him a week or 10 days more and he will give up. The first week he said: 'I've got English today.'
"The second week he said the same but with a different expression on his face... and the third week he went off for a siesta instead."
