The controversial 30-year-old has endured an injury-hit campaign after coming back from his long suspension he brought with him from England, but Barton has seen enough to believe his future lies in France.
"I hope to stay here," midfielder Barton told L'Equipe
"When I came, my idea was to become the best player in France. I was not this season, but I didn't see anything that would make me believe I could not become the best."
The former Manchester City midfielder still bears a grudge towards QPR and feels that the club left him out in the cold after receiving a 12-match suspension for his sending-off at the Etihad against City last season.
And it is this reason he indicated why he cannot return to Loftus Road.
"I don't think the club should pay any fee, QPR will let me leave on a free," he added.
"There is a clause in my contract that if Marseille wants to keep me they won't have to pay a fee.
"I could hardly go back to QPR, which dropped me in it when I had an incident.
"It would be like going back to a girlfriend who betrayed me."
