Kun scored for City in Sunday's Carabao Cup final triumph against Arsenal and spoke with Spanish reporters after the game.
He told El Larguero: "I like the Spanish Liga but I am happy in the English league, for now I have a contract and I am happy, I would like to continue but you never know..."
On City's prospects for the remainder of the season, Aguero continued: "The favourites for the Champions League are the big teams, but we are very good and if we continue in this way we will have our chances.
"The club has invested a lot to try to achieve a Champions League win and hopefully this year. Barcelona, Madrid, Bayern ... these are the ones that are always among the first four."
