Toure was suspended for six months last March after failing a drugs test, but since completing his ban he has struggled to get into the team, Joleon Lescott and Vincent Kompany having forged an impressive partnership at the heart of the Manchester City defence. Now Toure admits he may be forced to move on.
"It's hard to foresee oneself leaving during the January window when you're at City,” Toure was quoted as saying by The Sun.
"But everything can happen very quickly in football. It'll depend on how much playing time I get.
"Could I be interested in Paris St Germain? Again, it'll all be down to game time I get with City.
"I want to play matches and if things don't progress I'll ask myself questions.
"PSG are a big club these days, like City, Arsenal or AC Milan. They want to become one of the world's best clubs and are investing money in great players.
"They're not to be sneezed at. I can't think of a single player who would refuse to join PSG."
Toure was recently fined by the club for his drug ban - a penalty the defender had not been expecting - but he is hoping to prove he is still a valuable player for Manchester City.
"I was surprised to be fined by City. It was difficult for me, although the people at the club explained their reasons to me.
"I accepted it in order to put an end to the matter and to get back playing once more. I'm 30, at the peak of my career and I want to prove to certain people I'm still hungry and they're wrong about me. Playing so little since my suspension ended has been a tricky situation.
"I know it'll be hard for me to regain my first-team place, as the side is doing well and getting results.
"The main thing is to stay in form, so if the boss needs me I can answer the call.
"The six-month ban was tough for me. It came out of the blue. I hadn't expected it at all.
"Luckily I was able to train for five months with City and strengthen myself physically and mentally."
