AZ Alkmaar moved to within four points of leaders Ajax with a 5-1 drubbing of Utrecht.
Utrecht were unable to cope with AZ's slick, attacking play and fell behind to Stijn Schaars' (pictured) free kick on 25 minutes.
Things got worse shortly after the interval as Shota Arveladze doubled AZ's advantage and David Mendes da Silva made sure of victory with a brace of goals.
Maarten Martens added a fifth to cap an excellent day for AZ, but they blotted their copybook slightly as Marc-Antoine Fortune netted a consolation from the spot for Utrecht.
Feyenoord have been inconsistent this term, but they were on their best behaviour on Sunday as they claimed a 2-1 win at Roda JC.
