Joleon Lescott admitted that he might be forced to leave the club if he continues to be a substitute player.
Having cost almost 30 million euros in the summer of 2009, the defender is worried that he will no longer be called up to the England national team.
"Man City" manager Roberto Mancini's main center-back pairing consists of Vincent Kompany and Kolo Toure, while Lescott, who plays on the field, has to move to the left side.
"I am not happy with my situation," said Lescott. "I don't like sitting on the bench, and sometimes not even being registered for matches."
"Everything depends on me and the club. Of course, there are many high-level players in the team, so I didn't expect to play in every match, but when I get the chance, I think I perform well."
In the English championship this season, Lescott played 5 matches, and in the Europa League - 3.
