The 18-year old defender has emerged as a target for the likes of Paris Saint-Germain, Manchester United and Real Madrid but Lens president Gervais Martel insists the young gun will not be leaving this summer.
"Paris St Germain have made me an offer, that is probably the worst kept secret around," Martel told RMC.
"A second club is also interested in him, but he isn't necessarily guaranteed first-team football there either. The asking price is around 10million (£8.9million).
"Certain big overseas club have offered more, but I quickly shut the door on them!
"We are on the same wavelength as the player, it's all a question of timing. I don't think we are too far from finding a solution."
