Klaas-Jan Huntelaar scored twice as Ajax completed the first leg of a possible treble by cruising to a 4-0 win over Willem II in Sunday's KNVB Beker final.
Defenders Daley Blind and Rasmus Kristensen opened and closed the scoring at De Kuip, either side of Huntelaar's brace, as Erik ten Hag's side lifted the cup for the first time in almost a decade.
Ajax lead Tottenham Hotspur 1-0 in their Champions League semi-final tie and find themselves above PSV Eindhoven on goal difference at the top of Eredivisie, leaving them on course for three major honours.
