Davinson Sanchez has informed Ajax he wants to join Tottenham, reports the Independent.
The Colombia international is understood have rejected a move to Barcelona last year due to fears of a lack of game time.
But with Mauricio Pochettino believe to be interested in the 21-year-old, the defender has now revealed his desire to leave the Eredivisie club.
Sanchez’s importance was evident as last season’s Europa League finalists lost against their Eredivisie rivals for the first time in 52 years.
Despite Ajax having sold their top talent throughout their illustrious history, it is understood they are holding out for upwards of £45million.
And that would make him the club’s highest-ever sale — and record purchase for Spurs.
Sanchez, 21, is one of a number of top, young talents at the Amsterdam Arena, and would find Jan Vertonghen, Toby Alderweireld and Christian Eriksen as former Ajax players in North London.
He joined from Atletico Nacional last summer, and his performances have seen Barcelona among the clubs interested in signing him.
