The France international is in no rush to leave the Etihad Stdaium, having penned a long-term contract upon his arrival in 2011.
He is, however, aware that the time will come to move on at some stage.
A return to Marseille would certainly appeal to a man who graduated out of the academy system at Stade Velodrome, but Nasri concedes that such a switch forms no part of his immediate plans.
The 26-year-old told L'Equipe: "Clearly, economic reality stops me from thinking about playing at OM right now.
"In the future, I don't know yet. I would like to discover the MLS. I love American culture."
For now, Nasri remains very much part of the set-up at Manchester City, with new Blues boss Manuel Pellegrini having made it clear that he is counting on the talented playmaker to raise his game and rid himself of the inconsistencies which marred his 2012/13 campaign.
Nasri added: "I had a talk with Manuel Pellegrini. We'll see what happens.
"He came to me the first day and told me that he was counting on me, that I would be an important player, that I was going to play.
"We'll see - I'm not worrying about it. If I'm good, the coach will play me. He's just arrived and he has to get results."
