Wellington Phoenix
Currently: Seventh
Points: 29
Goal difference: -4
Highest possible finish: Fifth
Lowest possible finish: Seventh
Remaining games: Sydney FC (H), Brisbane Roar (A)
After losing a quintessential six-pointer to Western Sydney in mid-March, every one of the last four games became a must-win for Wellington if they were to stay alive in the fight for the Finals. They’ve achieved that in impressive fashion so far, dispatching the Jets 5-0 before a head-turning 3-0 win at Melbourne Victory on Sunday.
If Glory get a point in Perth on Saturday night, Phoenix’s season will be over, but when they kick-off against Sydney FC in Wellington earlier that evening, the door will still be ajar. That gives Wellington every motivation to continue their late-season renaissance against the Sky Blue juggernaut and Premiers Plate winners.
???? Unless FeverBot is lying to me, this math is a little off? let's say Perth draw on Saturday and the Phoenix win, that would bring the Glory to 34 points and the Phoenix to 32, therefore it's still mathematically possible for us to snatch a place in the top six in the last round. Heck, it's even possible for us to catch the Wanderers but still finish behind Perth.
