Feyenoord are aware of mounting interest in teenage midfielder Rodney Kongolo, but insist no approach has been received.
The highly-rated 15-year-old is the latest product of the club's famed academy system to draw admiring glances from outside of Holland.
Chelsea, Manchester City and Arsenal are all believed to be keen on taking Kongolo to England.
All three Premier League clubs have made successful raids on Feyenoord in the past, with Jeffrey Bruma and Nathan Ake having moved to Stamford Bridge, Kyle Ebecilio to the Emirates and Karim Relik to the Etihad Stadium.
Feyenoord are hoping to avoid seeing another hot prospect slip through their grasp, but can do little to prevent Kongolo from leaving as he is too young to be tied down on professional terms.
They insist they have had no contact with interested parties at present, but acknowledge that a number of their most promising talents have fallen under the radar of other sides.
Technical director Martin van Geel told Algemeen Dagblad: "Our youth players are being followed, we are aware of that.
"But we are not aware of any serious interest in Rodney. He is only 15 years old and no official contact has been made with us regarding his availability."
