Games in Holland don't come much bigger than Feyenoord vs PSV Eindhoven.
Two of the country's big-hitters met for the first time in 2018/19 on Sunday, with Feyenoord ending PSV's perfect start to the season.
The side from Rotterdam won 2-1 thanks to goals from Nicolai Jorgensen and Sam Larsson.
Highly-rated PSV winger Steven Bergwijn managed to pull a goal back for the Eredivise leaders, but they couldn't muster an equaliser.
The results means PSV are now just two points ahead of Ajax, who comfortably beat ADO Den Haag 5-1 in Amsterdam.
However, PSV certainly had their chances to equalise against Feyenoord, but they were prevented from doing so under quite extraordinary circumstances in the 75th minute.
A video has appeared on Twitter showing Feyenoord fans throwing a second ball onto the pitch when the visitors appeared to be on the cusp of scoring.
You can watch the footage below.
Have you ever seen anything quite like that?
The referee simply has to be bring the play to a halt, with the PSV players understandably fuming at the incident.
However, what could the officials do? Allow the play to go on with two balls on the pitch? Absolutely not.
And it's not like he could simply send off the entire crowd and award a penalty to the visitors, so you do have to feel for the referee on this one.
Whether Feyenoord will receive some form of punishment from the Dutch FA remains to be seen, but a fine would be a punishment befitting of the crime.
It's hard to think of an incident quite like it, although Darren Bent's infamous 'beach-ball goal' for Sunderland against Liverpool back in 2009 certainly springs to mind.
At least this time, the officials made the right call this time and actually brought the match to a halt.
