Lille have set their asking price for Sven Botman ahead of the January market.
The Holland defender is being linked with several major European rivals, with Roma and Newcastle United both keen, reports TMW.
The French champions are prepared to sell Botman next month for €30m.
Botman's deal runs to 2025 and Lille have made it clear he will only leave for a straight sale.
The Dutchman has played 16 matches this season.
