Saya mau tau Asal muasal dari Derbi Sydney

The competitive nature of the Sydney Derby is largely based upon the historical, cultural and geographical divide between the Greater Western Sydney region (home to Western Sydney Wanderers), and eastern, southern and northern Sydney (home to Sydney FC). The cultural makeup of the two clubs fits into this wider divide. As Sydney FC began their life in Moore Park they took on the "Bling FC" moniker, with the ownership intent on building Sydney FC into the "glamour club" of the A-League Men.

The rivalry between the two clubs also stems from the A-League Men's establishment. Prior to the introduction of Western Sydney Wanderers in the A-League Men, the only club to be based in the city was Sydney FC as part of FFA's 'one-city, one-team' policy for the newly established league. This deal gave Sydney FC a five-year city exclusivity, allowing the club grow throughout the region without competition. Sydney FC was not entirely embraced by the region, as the club's original intention to play at Parramatta Stadium was later changed by FFA chairman Frank Lowy. Lowy's decision for the club to play out of the Sydney Football Stadium left some fans in Sydney's west feeling alienated from the club. Sydney FC's perceived exclusion of the western region mirrored the pre-existing cultural and social divide of the city.

In 2008, FFA sought to introduce the new western Sydney-based Sydney Rovers into the A-League Men. This later proved unsuccessful with the club dissolving due to technical and financial reasons. During the time period prior to the disbanding of Sydney Rovers, two matches hosted by Sydney FC were played at Parramatta Stadium. In the first, a pocket of supporters came out bearing banners in support of the new western Sydney team with the Sydney FC active support group The Cove responding by chanting against the support for the new club.

On 4 April 2012, the collapse of Gold Coast United brought about the creation of Western Sydney Wanderers. FFA's decision for the club to be community oriented proved successful with the local western Sydney community soon backing the club, a club they had long called for, one that would represent the western region.
