There's something very special about the Sydney derby, just ask Filip Holosko. It's not the most passionate fixture in the world, the biggest or the most important, but it's one of the few great grudge matches played in a large venue with an even split of rival supporters not segregated.

"It's half and half, the atmosphere here is perfect," Holosko said.

Fandom: Sydney FC and Western Sydney Wanderers fans.

With 20,000 Sydney FC fans and just as many Wanderers supporters at Allianz Stadium on Saturday night, such a match can lay claim to being one of the most unique derbies in world football. Away supporters aren't limited to their designated bay, making for an unrivalled tension in this country that feeds off historic cultural narratives.

It's a rivalry 108 years of rugby league couldn't replicate in the stands, and one that FFA chief executive David Gallop only saw in football.
