Ronald Koeman's side won their fifth successive league game on Sunday, 2-0 at home to RKC Waalwijk, which meant the title race was extended by a further week.
Ajax's 1-1 draw at Vitesse means there is now a six-point gap between the two sides with three matches remaining.
And the leaders remain firm favourites, safe in the knowledge that, if they can better Feyenoord's result when they host ADO Den Haag on Sunday, they will claim their fourth successive crown.
Frank de Boer's men have stuttered slightly of late though, drawing three of their last five Eredivisie games to allow Feyenoord to make up some ground.
Koeman's charges will be out to continue their recent good run of form at fifth-placed PSV, who have lost their last two matches and have dropped out of the top four, one point off automatic UEFA Europa League qualification.
At the wrong end of the table, Roda JC's bottom-three finish will be confirmed if they fail to win at third-placed Twente, who will still feel in with a chance of a top-two spot and a place in next season's UEFA Champions League qualifying round.
Michel Jansen's men lie four points behind Feyenoord and will be strong favourites for victory against a Roda side who have won just once in their past 11 league games.
