The Western Sydney Wanderers displayed on Saturday why they will potentially be Australia's biggest sporting club.
In a display by the Wanderers on the field and by the RBB in the stands, the club showed why it will be one day tackle the giants of European football.
This match had been marked as the battle for the city, the derby nobody wanted to lose.
Before kick-off, there was a nervous excitement in the stadium.
With two thirds of the stadium in sky blue and the other in red and black, Allianz was near capacity.
The match started with a bang as western Sydney fans let off fireworks and flares in the away bay.
The RBB and Cove traded blows and went chant for chant - giving the game an atmosphere that only football can.
The Wanderers were quickly on top and made it count as Italian Iacopo La Rocca poked home the opener.
The goal only made the RBB louder and brought the non-active side supporters into play with the "who do we sing for" chant.
This was followed by a great solo effort from Shinji Ono as the Wanderers made it 2-0 in the 27th minute.
As the match went on the RBB got louder, involving all Wanderers fans in the stadium whenever possible.
They focused on songs that highlighted where they were from and how they were proud of it.
These chants included "West" and "We're from the streets of western Sydney".
As the Cove began to lose momentum, the RBB continued its relentless chanting.
They sang the full 90 minutes and were rewarded for it with a victory over their bitter rivals.
The players applauded the supporters and led them in the customary "Who do you sing for" chant.
Australia's biggest city was red and black, as thousands of Western Sydney fans travelled home victorious.
I have a feeling it will be a while before something wipes the smile of their faces.
The Wanderers now look ahead to Adelaide at Pirtek stadium on Friday night.
