Heerenveen moved to within three points of fifth-placed Feyenoord thanks to a 5-1 trouncing of Heracles Almelo on Friday night.
The Friesland-based side are looking to mount a European challenge in the second half of the season and had little difficulty in disposing of their struggling opponents.
Lasse Nilsson set the tone for the night when he scored after just two minutes, and, predictably, Brazilian striker Afonso Alves continued his stunning campaign with a brace before half-time (39, 43).
The former Malmo man has now registered 21 goals in 22 games this season and another starring role is sure to intensify talk of a potential January move to Manchester City.
Kwame Quansah (51) grabbed a goal back for Heracles, but Danijel Pranjic (62) and Canadian international Rob Friend (78) rounded off a superb night for Heerenveen.
