PSV Eindhoven's march towards the title shows no signs of faltering, as they claimed a 4-1 win over Heerenveen on Saturday.
Guus Hiddink's men have been in hot form domestically for some time and Heerenveen were the latest team to wilt in the face of some fine attacking play.
Arouna Kone has been a big hit for PSV and he netted twice at the Philips Stadion, as they claimed their ninth straight win.
Veteran midfielder Philip Cocu and defender Alex were also on target, the latter netting a fine free kick, with Mark de Vries's strike proving nothing more than a consolation.
Willem II remain second from bottom, but they secured a confidence-boosting 5-0 win over Groningen.
The goals were shared around, with Jose Valencia, Anouar Hadouir, Nuelson Wau, Iwan Redan and Moussa Dembele all getting their names on the scoresheet.
Relegation looks certain for RBC Roosendaal, who were beaten by NAC Breda.
An own goal from Akram Roumani on 36 minutes had RBC in trouble and their woes were compounded when Arne Slot netted a second just after the break.
Bjoern Daelemans gave RBC hope on 58 minutes, but they could not find a leveller.
Two goals in the last ten minutes from Boldiszard Boldor handed Roda JC a 3-1 win at Vitesse Arnhem.
Vitesse had led through Siepe Blondelle, but were pegged back by a goal from Simon Cziommer before the spotlight was hogged by Boldor.
