Tevez: I will leave City
The news is likely to spark a worldwide transfer scramble for the 27-year-old star and comes just days after City manager Roberto Mancini claimed the Argentine would be staying.
"I want to leave Manchester City," Tevez told Argentine station Radio del Plata.
"Football has changed a lot for me and I don't know if I will even make it to the next World Cup.
"And that has nothing to do with whether I'm selected or not. I've been treated very well here and I'm grateful.
"I also gave my everything for the club to receive the results it has had. But I need a change of scene."
"To go back to Boca Juniors would be beautiful but it is very difficult," admitted Tevez. "If we're speaking seriously, financial issues would make my return difficult."
