It has long been looking like a changing of the guard might just be on the horizon in the Dutch Eredivisie - yesterday there was big hint of confirmation on that fact.
Perennial title challengers PSV Eindhoven knew they were in for a scrap against the impressive looking Vitesse Arnhem side of this season - but would never have predicted what would have happened next.
They were thrashed 6-2 by the travelling side at the Philips Stadion.
And of course Chelsea players were involved.
The club have several players out on loan at the Dutch table toppers including talented Brazilian Lucas Piazon - who bagged the opening goal of the game.
Maurice Depay grabbed one back for PSV before all hell broke loose in the final half an hour.
Christian Atsu, another Chelsea loanee, delivered the perfect cross for the second Vitesse goal - which was tucked away by Japanese international Mike Havenaar. Then Piazon turned provider. He dinked a delightful ball over the top for Kevin Leerdam, who took on Jeroen Zoet in goal to tap into an empty net.
Manchester City loanee Karim Rekik then gave the home side hope at 3-2 - before the Chelsea show continued in the last five minutes.
First Patrick van Aanholt set up Dutch international Davy Propper to make it four - before the left-back and Piazon played a delightful one-two to set him in for number five.
But Vitesse were not done there. Once again van Aanholt turned provider for Propper who wrapped up a famous away victory for the travelling party - PSV Eindhoven 2 - 6 Vitesse Arnhem.
And all six goals were either scored by Chelsea players (Piazon, van Aanholt) or set up by Chelsea players (Atsu, Piazon , van Aanholt ).
A stunning victory then for Chelsea - I mean Vitesse - over PSV Eindhoven.
