Manchester City boss Manuel Pellegrini is not worrying about the prospect of losing Sergio Aguero in the summer.
Samir Nasri has revealed he is ready to open talks with Manchester City about extending his stay at the Etihad Stadium.
The midfielder is alleged to have demanded a £3.5million pay-off to end his contract and push through a permanent switch to France.
However, Barton has taken to Twitter to play down the claims, insisting he has not had any such conversation with the club's hierarchy.
"A lot of rumours circulating about me, Marseille and QPR in last few days. As usual loads of #nonsense," he tweeted.
"I haven't had a conversation with anyone at QPR since February. When I told them Marseille had offered me 3 years. That was last I heard."
The 30-year-old impressed in his first season with L'OM, despite suffering several injuries in what turned out to be a frustrating campaign at times.
And Barton ended his discussion on the topic with a message for his current employer: "They know where I am if they want to talk."
