The 24-year-old has been linked with a move away from the Etihad, with Real Madrid reportedly monitoring the Argentine's situation.
However, on Friday, City chief executive Ferran Soriano insisted the club have no intention of allowing Aguero, who still has three years left on his contract, to leave.
And now Aguero has committed himself to the club.
"There are always rumours in the summer," the former Atletico Madrid player told The Sun. "But I am very happy at City. I'm going to work hard and everything else is just rumours.
"Every player wants to play in big teams that win titles. We didn't win anything last season but we have won trophies in the last few years so there is no reason to go."
