Dutch pundit Henk Spaan fears Ajax will lose Justin Kluivert this summer.

Kluivert is being linked with Manchester United and Spaan is critical of the developments, with his agent Mino Raiola at the centre of the deal.

Spaan wrote for Het Parool: "Where is Samet Bulut, a striker from Ajax youth and former teammate of Nouri and Van de Beek? Bulut went with Raiola at the time. Now he is playing in the second in Almere, Mino prefers to be in Monaco, Nice or Manchester."

He also cites Donyell Malen, former of Arsenal, and Ricardo Kishna as examples.

"Malen was perhaps sixteen. Where does he play now? In the second of PSV. Ricardo Kishna played in the first of Ajax.

"Raiola sold him as an adolescent to Lazio, which loaned him to Lille, which loaned him to ADO.

"Before Justin Kluivert starts to be pushed between Raiola and (Marc) Overmars, that boy must hit the table with his fist. If the agent also makes these negotiations successful, Justin's career suddenly becomes less clear."
