A review of the weekend's action in Holland's Eredivisie.
FC Twente's Eredivisie title hopes suffered a blow after they were beaten 4-2 at home by fifth-placed FC Utrecht.
Jens Toornstra's 32nd minute strike put Utrecht ahead before Twente defender Rasmus Bengtsson saw red a minute before the break.
Jacob Mulenga scored from the spot on the stroke of half-time and although Dusan Tadic reduced the arrears after 56 minutes, Dave Bulthuis soon restored the visitor's two-goal lead.
Tadic scored from the spot with 16 minutes left, but Mike van der Hoorn found the target for Utrecht to leave Steve McClaren's side four points off leaders PSV.
Second-placed Ajax are three points off top spot following a comfortable 3-0 win at VVV Venlo.
Striker Siem De Jong set the ball rolling in the 34th minute, before second-half strikes from Viktor Fischer and substitute Derk Boerrigter sealed the win.
Feyenoord in fourth are five points off top spot after they won 3-1 at Willem II.
Graziano Pelle gave the visitors a 10th minute lead before Virgil Misidjan equalised from the penalty spot seven minutes before the break. Tony Vilhena scored a second half brace for Feyenoord to ensure victory.
Elsewhere, NEC Nijmegen beat Vitesse Arnhem 2-1 thanks to goals from Remy Amieux in the 38th minute and Ruud Boymans in the 67th, with Mike Havenaar on target for Vitesse.
On Saturday, PSV Eindhoven underlined their superiority at the top as they thrashed ADO Den Haag 7-0.
With FC Twente not in action until on Sunday when they face FC Utrecht, PSV kept the limelight all to themselves with a sumptuous display against one of their favourite opponents.
Six of the goals came in the second half, with Georgino Wijnaldum's ninth minute goal barely a warning of what was to come.
The second did not come until just before the hour mark, and it was gift-wrapped as Christian Supusepa turned Jeremain Lens' cross into his own net.
The fireworks started soon after with two goals in three minutes from Dries Mertens and Lens making it 4-0 by the 66th minute, the first a fine curling free-kick from Lens.
They then piled it on in the final 10 minutes. Jurgen Locadia, on as a substitute, got the fifth in the 80th minute, before Mertens and Wijnaldum each got their second of the evening.
With most of the rest of the leading pack not in action on Saturday, it was towards the other end of the table where there was the most movement.
A 90th minute own goal saw Roda JC edge their way out of the bottom three with a 3-3 home draw against Heracles Almelo, having come back from 3-1 down after giving up an early lead.
Sanharib Malki put them in front after just 27 seconds, but Marko Vejinovic levelled after quarter of an hour and Ninos Gouriye then had the visitors in front four minutes before the break.
Just seconds into the second half Dario Vujicevic slipped the ball through the goalkeeper's legs for his first goal since April 2011 and Heracles were cruising at 3-1.
But Danilo Pereira's 57th minute strike got Roda back in it before they snatched a last-gasp point thanks to Dorda's mistake.
They move above PEC Zwolle, who went down 3-0 at NAC Breda - having played 50 minutes with 10 men as NAC pulled themselves away from immediate danger.
Anthony Lurling was the star of the show, winning a penalty and setting up the other two goals.
It was all square until five minutes before half-time, when Lurling rounded visiting goalkeeper Diederik Boer but then saw his shot blocked on the line by Joost Broerse.
The defender saw red before Jordy Buijs rifled home the penalty.
Lurling then cracked a shot against the crossbar moments in the second half, but the ball fell for Nemanja Gudelj to sweep it home.
Lurling's work in the build-up to the third goal was more straightforward as he played in Anouar Hadouir to finish in the 68th minute.
FC Groningen likewise pulled clear of trouble with a 1-0 away win over AZ Alkmaar, who also finished with 10 men.
Andraz Kirm got the goal in the 27th minute after capitalising on a mistake by Etienne Reijnen to scoop up the ball.
Jozy Altidore, who spent much of the week in the spotlight after suffering racist abuse during AZ's cup win at FC Den Bosch in midweek, squandered good chances to bring his side level before their chances suffered further damage with the 64th dismissal of Viktor Elm for a tackle from behind.
On Friday, Heerenveen picked up a vital win in their bid to avoid relegation from the Eredivisie after they beat RKC Waalwijk 1-0 at the Mandemakers Stadion.
The visitors looked to be up against it after Ramon Zomer was sent off four minutes into the second half, but with seven minutes left RKC also went down to 10 men after goalkeeper Jeroen Zoet saw red.
And Marco van Basten's side scored a winner five minutes from time courtesy of a Filip Djuricic penalty.
