The former England international, who has been plagued by injuries in recent years, joined Roberto Mancini's side last August after leaving city rivals United.
However, he played just four times - but only once in the Barclays Premier League with a 13-minute appearance in October - and scored a solitary goal in a Carling Cup victory over Birmingham. The 31-year-old's last outing came in the 3-2 FA Cup third-round defeat to United on January 8 when he played the final eight minutes.
