Ajax are inviting offers for Noussair Mazraoui.
With his deal about to enter the final year, Ajax chief Marc Overmars has seen his attempts to open new contract talks resisted by the right-back.
As such, AD says Ajax will now seek to sell the youngster.
Tottenham and Arsenal are both keen on Mazraoui, along with German giants Bayern Munich.
It's been suggested Ajax would be willing to sell for a knockdown €10m in the coming months.
