Saint Etienne vice president Dominique Rocheteau won't consider selling Kurt Zouma this month.
The France international has declared he hopes to eventually play for Jose Mourinho at Chelsea.
"We talk about him now because he has talent," Rocheteau told beIN Sport.
"It's true, many clubs are watching, it was the case last season, many foreign clubs came to see [him]. But today, there's no [chance] he leaves in the winter transfer window.
"He will remain with us until the end of the season."
