Ajax held as chasing pair win
Ajax's run towards the Eredivisie title was checked on Sunday as they were held to a goalless draw at NAC Breda.
The Amsterdammers failed to break down a NAC side that has not won in five league games.
Ajax's lead therefore remained at seven points, with Twente joining Vitesse Arnhem as their closest rivals following a 2-1 win at home to AZ Alkmaar.
Twente did it the hard way as they fell behind to Steven Berghuis' 40th-minute goal.
Substitute Youness Mokhtar levelled on 69 minutes before Dusan Tadic struck the winner in injury time.
Feyenoord were less troubled as goals from Ruud Vormer (49) and Lex Immers (64) secured a 2-0 triumph at home to Heerenveen.
Zwolle are three points clear in the race for the final Europa league play-off place after beating Go Ahead Eagles 2-0.
Jesper Drost (45) and Guyon Fernandez (90) got the goals to end Zwolle's five-game winless run.
NEC Nijmegen's 2-2 draw with FC Utrecht was enough to lift them off the foot of the table.
The hosts twice came from behind for their precious point with Michael Higdon (24) and Jakob Jantscher (60) cancelling out goals from Dave Bulthuis (22) and Jens Toornstra (45).
