Barton is on-loan at l'OM from QPR this season.
He said: "We have not talked about that. We have ambitions for the title and all transfer rumors can wait. I have a two-year contract with Queens Park Rangers, but at the end of this season I do not see a return to QPR.
"I would stay at OM. I am often asked this question about my future and I want to stay. Marseille believed in me when nobody believed in me. I want to repay this trust and I want to do so through my performances."
