Lens president Gervais Martel claims he has rejected bids of over €10million for teenage centre-back Raphael Varane from "big overseas clubs".
Varane emerged as a regular for Lens in the 2010-11 campaign, though his side were relegated from Ligue 1 after finishing second from bottom.
The 18-year-old has been linked with the likes of Manchester United and Real Madrid and while Martel didn't name the clubs in question, he claimed that big money bids have been tabled.
But the Lens chief insisted he is unwilling to let Varane move to a club where he will not be a regular, leaving a switch to another French outfit the likeliest outcome.
"Paris St Germain have made me an offer, that is probably the worst kept secret around," Martel told RMC radio station.
"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 euros (£8.9 million).
"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.''
