Lens president Gervais Martel has hinted they've rejected a bid from Manchester United for Raphael Varane.
United recently launched a bid for Varane after tracking the 18-year-old for a number of months, while Real Madrid were also thought to have tabled an offer.
"The asking price is around 10m," Martel told radio station RMC.
"Certain big overseas clubs have offered more, but I quickly shut the door on them."
