The striker has long been linked with a move away from City.
But he told The Sun: "There are rumours about my future in England, Italy or Spain but I'm saying nothing.
"I am all about Manchester City and the deal I have here. It's my obsession to win the title again with City.
"Roberto Mancini is the boss and I accept his orders. He's always talking to us and is satisfied with my work.
"To play in a team like City's is easy because of the quality of my companions. Every forward thinks he should be in the team but it's up to each of us to give him problems over who he selects."
