Chelsea will sell attacking midfielder Marko Marin to Galatasaray, Yeni Safak has confirmed.
There is no place for the 27-year-old, who spent this season on loan at Trabzonspor, in Antonio Conte's squad.
At the start of the year, the German admitted that a return to Chelsea was very unlikely.
"It's difficult [to return]," he was quoted as saying by ESPN.
"You not only need a few good matches at Trabzonspor, but a very strong year. You never know, but right now it does not look like [a Chelsea return] it.
"I personally thought that it's about time to make the next step [when I left].
"I joined Chelsea and the pre-season was super, until I sustained an injury. [I got] a muscle bundle tear [and was] out for three months. That makes it difficult... I have learned a lot [in Turkey], and have never rued making this step.
"My career only starts now. I am in the best age for a footballer.
"I have collected a lot of experience, lived in London, Seville, Florence, Brussels, got to know many new languages and leagues. I could have left for the UAE last summer but I want to show my worth in Europe, and I am on a good path."
