Galatasaray chief Cenk Ergun cannot rule out selling Burak Yilmaz in January.
The striker is highly admired by West Ham boss Slaven Bilic, who saw plenty of Yilmaz while in charge of Besiktas.
Ergun said: "At the moment we have no plans related to this issue.
"A transfer in January is always difficult. But for Burak, I want to be honest with him, so we will listen to offers, we'll sit at the table."
Bilic is a big fan of the striker.
He said in August: "Burak is both Galatasaray's and Turkey's most important striker. He is one of my favourite players."
