The seemingly unwanted former QPR captain had been in discussions over an unlikely switch to Ligue 1 but declares on Twitter that he is "heartbroken" after negotiations stall
The controversial figure was stripped of the Rs captaincy after being sent off on the final day of last season, incurring a 12-match ban of which 10 are still to be played, and manager Mark Hughes is reported to be willing to lose the former Newcastle man for free.

"Doesn't look like this Marseille thing is gonna happen now," Barton wrote. "'Whatever doesn't kill you make you stronger' #heartbroken.
"Why can't things just be simple..."
The 29-year-old had previously Tweeted extensively about his desire to leave Loftus Road, declaring: "Maybe it's just time to move on. I enjoyed parts of last season and I believe I am more than capable of playing this year. But the manager doesn't. Such is life.
"I have no problem with this as its my fault I am banned for 12(10 now) games. When a person [makes] a decision he has to stand by that. I respect Hughes for this. I don't agree but I accept his decision.
"I am not the type of player to sit on the sidelines and take the cash. It's not me. I could do that for the next 3 years but it's not me. I want to play football.
"Hopefully the QPR fans will accept that. I offered to resign from the club/contract when I got my ban. @tonyfernandes [and] @Amit_Bhatia99 will testify that I am telling the truth."
