Denzel Dumfries scored a late winner as PSV Eindhoven beat bottom side Groningen 2-1 to stay perfect in the Eredivisie and go eight points clear at the top.
Samir Memisevic's successful penalty filled struggling Groningen with confidence heading towards half-time but Donyell Malen burst their bubble when converting Dumfries' assist in stoppage time.
Time was running out at the Hitachi Capital Mobility Stadium when Dumfries dribbled through the home defence before slotting home to ensure a 10th win from as many games for Mark van Bommel's league leaders.
Heracles missed the chance to go above Feyenoord and take third place as Mike van Duinen forced a 1-1 draw for PEC Zwolle.

Furdjel Narsingh scored one and set up another as De Graafschap pulled away from the danger zone with a 4-1 triumph at home to 10-man Excelsior.
