Agents for William Saliba refused to shut the door on a summer sale from Arsenal.
Currently on-loan with Olympique Marseille, Saliba is expected to return to the Gunners at the end of the season.
La Provence says agents close to Saliba insist nothing is set in stone, though remaining with OM is far from guaranteed.
Atletico Madrid have made tentative contact, while from Italy interest has arrived from AC Milan and Napoli.
Just this week, OM coach Jorge Sampaoli said: "I hope we will be able to retain a player like him, who knows is the club. But I don't know if it depends on OM, William or Arsenal. I do not know the contours of this transfer."
