The Argentine forward had been linked with a move to Spanish giants Real Madrid, but his new deal will run until 2017.
“I’m very happy at City and I feel very appreciated. It’s been barely two years since I’ve arrived and sometimes I feel like I’ve been here for all my life.
“I have a fantastic relationship with the fans. I can never forget that moment. I am looking forward to next season and pushing hard to win the title again.”
