Barton believes he will not return to Queens Park Rangers if they are relegated, while he has also opened talks about extending his stay at Marseille.
Barton, 30, is currently on loan at the French club until the end of the season, when he will be due to return to west London.
But the midfielder feels he is more likely to be playing his football at Stade Velodrome than Loftus Road next season.
Barton, who still has two years left on his QPR contract.
QPR are currently bottom of the Premier League table, eight points adrift of safety, having still yet to record a win this season.
Joey Barton: "For me to be part of the side that stayed up and not be part of the side that went down, it would be difficult for me to go back.
"I haven't closed my mind to it although I would really like to stay here.
"I'm in a good space mentally. I've held preliminary talks with Marseille about extending my stay here. They have asked me whether I would stay beyond the loan period.
"The likelihood is, unless there is a massive turnaround in fortunes, QPR will be in the Championship next season.
"What it seems to me as a neutral - and I am in France, no matter that I am contracted - is that they have got a big case of a lot of good individuals, a lot of good quality individuals, but not a good team.
"It didn't end in great circumstances in west London for me.
"I know there has been a change in terms of the management structure, but something like that, and what goes on around that, lives with you beyond a managerial change.
"Harry Redknapp's record speaks for itself.
"This time last year he was being talked about as the only successor to Fabio Capello. He has always done well with players and always got players on board. He is a really good man-manager.
"If anyone can pull the players together, a manager of Redknapp's calibre is capable of that. They are in with a good chance now with Harry there."

This confirms the former Toon midfielder has a head full of broken toys.
