Klaas Jan Huntelaar was his side's star man as he hit four goals, as Ajax scored eight on their travels to De Graafschap, in an entertaining league opener on Sunday.
Somewhat surprisingly, given the game finished 8-1, it took Ajax 36 minutes to break the deadlock, as Luis Suarez set up Huntelaar, before doubling their lead before the break.
Hedwiges Maduro added a double of his own, before efforts from Kennedy Bakircioglu and Huntelaar again embarrassed the home side.
Donny de Groot registered with the scantest of consolations for De Graafschap, but his efforts proved very much in vain, as Huntelaar scored twice more before the end.
Feyenoord too were big winners on their travels as they beat Utrecht 3-0.
Luigi Bruins gave them a first half lead, before in the second half Nick Hofs and Roy Makaay completed the job.
Joining the away day winners were PSV Eindhoven, as late goals from Ibrahim Afellay and Mike Zonneveld secured a 2-0 win over Heracles Almelo.
Vitesse Arnhem made it a clean sweep of away wins as they came from behind to beat Sparta Rotterdam.
Charles Dissels put the home side into a 20th lead but goals from Remco van der Schaaf and Gill Swerts in the second period secured an impressive three point haul for Vitesse.
