The striker insists his head was not turned by talk of interest from Real Madrid.
He said: "They were only rumours. I have a commitment at Manchester City, which is a great club.
"I am happy to be part of a team that is growing up very fast. I am happy in Manchester, two years have gone by and I expect that we can do big things in the next few years.
"You can't win the title every year, but we finished second and played in the FA Cup final. I hope next season we win titles again."
