Lyon have set their price for Bruno Guimaraes.
Acknowledging the interest, Guimaraes said this week: "I don't like to think too much. I leave that to my managers, it's up to them to solve it. My goal is to bring Lyon to the place it deserves."
Should either club want to prize Guimaraes away from France, they'll need to open their chequebooks.
Calciomercato.com says Lyon are demanding at least 50 million euros to part with the 24-year-old.
Guimaraes, who made 37 appearances for Lyon last season, is under contract until 2024.
