Carlos Tevez feels joining Manchester City was the biggest mistake of his life, it has been revealed.
The Sun says if he does not get his wish to exit Eastlands, the Argentina striker may even quit football completely.
It's also understood he has told friends that joining City was the biggest mistake of his life.
City confirmed early yesterday they had turned down a transfer request from the player and hinted they would hold him to a contract due to run to 2014.
That brought a swift response from Tevez, who issued a statement of his own saying his mind was made up.
The 26-year-old said: "I can confirm I have handed a transfer request to the chairman of Manchester City.
"Now I need to clear my head and think, because this is an important part of my career.
"My feelings have not changed and it is regrettable we have reached this situation. But it is something I have felt for some time and I have spent many hours thinking this through."
