Matthijs de Ligt has informed Ajax he wishes to leave this summer.
The 18 year-old defender, reports De Telegraaf, has told management he wants to be sold.
De Ligt is attracting interest from across Europe, with Manchester City, Arsenal and Tottenham all keen, along with Barcelona.
Interestingly, Italian super agent Mino Raiola has joined De Ligt's camp, working with his prime representative, Barry Hulshoff, to find him the right club.
Ajax will demand at least €55m to sell the youngster.
