The ex-Atletico Madrid star still has three years left on his contract and has confirmed he is not looking to leave.
Aguero, 24, said: "There are always rumours in the summer. 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."
