Ajax eased to a comfortable 5-0 win over Willem II in the Eredivisie after a first-half flourish saw them out of sight at half time.
Striker Kolbeinn Sigthorsson got the ball rolling with a neat finish from Lucas Anderson's pass, before a deadly counter saw the hosts go from defence to attack in a three pass move which was finished by Arkadiusz Milik.
Joel Veltman scored a neat third just four minutes later, as he raced on to Lasse Schone's pass before deftly lifting the ball over the onrushing keeper.
Anderson got his third assist minutes before half time as he played a measured through ball for Milik to slot home.
The home side were more relaxed in the second half, but the still managed to add a fifth, with Davy Klaassen sliding at the far post to turn in Milik's cross.
