Simple, really. Of the three teams in the running for the Championship, who needs it more? Perth, Central Coast, or Brisbane? Brisbane-New Owners. Want to be the 'Barcelona of Asia.' A second title and second ACL appearance would be a good start, a would help convince the new owners to spend cash on the squad and facilities. Trophies also bring fans. Back to back titles will continue to help attendance. Central Coast-Validation. The second best team in Australia unless they win the double this year. If they lose, I see Graham Arnold leaving for Sydney FC, and Matt Ryan going to Europe. They win, they might both stay on another year. And a title after the two seasons they've had would be icing on the cake for the fans. Perth-Winning would be epic for long suffering Perth. Would also convince the owner to carry on with the team, keep more of the players then he had planned. Not to mention, you know Perth fans will turn out in greater numbers if they have a champion again after so many years.
Perth need it more, then the other two clubs who already have made their reputation. Not that Perth really deserve it, as they've totally arsed their way to the GF, but they have made it.
