Willem II moved a step closer to relegation from the Eredivisie today with a humiliating loss at Feyenoord.
Luc Castaignos and Ryo Miyaichi bagged two goals each, while Bruno Martins Indi and Georgino Wijnaldum were also on the scoresheet as the hosts ran riot at De Kuip.
Andreas Lasnik had given Willem II the lead, but the Tilburg side then crumbled to slip to their 23rd defeat this season.
They remain five points adrift at the foot of the table with three games remaining.
Things seemed to be going well when Lasnik found the target after 20 minutes, curling a free-kick from 25 yards into the top right corner.
But their lead lasted just seven minutes with Castaignos bundling home the rebound after Wijnaldum's header had been blocked on the line by Giovanni Gravenbeek.
Another goal followed two minutes later thanks to Miyaichi, who ran onto a pass from Marcel Meeuwis before turning in a low shot from 12 yards.
The floodgates then opened after the interval. Martins Indi made it 3-1 10 minutes into the second half with a powerful header into the top right corner, and Castaignos added a penalty two minutes later having been brought down in the area by Bart Biemans.
Willem II thought they had scored again in the 68th minute when confusion in the Feyenoord defence allowed Marlon Pereira to pick up the ball on the left side of the area and fire home.
However, the shot was ruled out by referee Christof Dierick, who deemed the ball had already crossed the goalline although television replays suggested otherwise.
The damage had already been done, though, and Wijnaldum got in on the scoring act after 74 minutes with a neat lob over the head of goalkeeper Vladan Kujovic.
And the rout was completed nine minutes from time by Miyaichi, who had a simple tap-in after Kujovic had parried another attempted lob from Wijnaldum.
