Ziyech has fallen out with management and is ready to quit in January, with Rennes keen.
The Morocco international declared: "Galatasaray, it's over for me, I told them I'm leaving in January. They don't ask me anything anymore, I do what I want.
"I've never seen such a bad coach as Okan Buruk. If Galatasaray can win the title? I don't care... Leave me alone, no matter what happens. I already regret coming.
"I was supposed to leave at the beginning of the season, but they didn't want to. I'm leaving in January."
