Sergio's Argentinian team-mate Tevez returned to help City land the title, but is now being linked with a move to Italian champions Juventus.
He told the People: "We won the title together in a special way. Carlos is a very good person. He returned, sorted out his things and was important for the team. Every time he had to play he did very well.
"For us, it was good to have him in the side and hopefully that will continue, but we have not spoken about his future.
"Today I'm thinking only of City. I will go back there and play in the Champions League, which is a spectacular tournament in which everyone wants to play.
"Then, in the more distant future, I do not know what will happen. I do of course have the dream that I'd like to go back to Independiente and finish my career at the club where I started, but that is a long way off."
