Adelaide's win over Sydney FC on Saturday night has put the Reds in pole position – for now, anyway –in the race for the premiers' plate.
Western Sydney Wanderers, with their easy victory over Central Coast on Friday night had temporarily hit the front only to be overtaken by Guillermo Amor's men.
Brisbane Roar can go to the top of the pile in the early game on Sunday if they defeat Newcastle at Suncorp.
With nothing to play for the Jets might give the Roar a fright, but there is surely too much at stake for John Aloisi's men to slip up at this stage of proceedings.
Which means that the acid is on John van 't Schip's side to take three points against an in-form Perth Glory at nib Stadium in the final match of the round.
If City win they can set up a potential winner take all showdown with Adelaide next Friday night at AAMI Park.
City know that with their exceptional goal difference – plus 22 – they control their own fate.
If they win their two final matches the only team that can match their points tally is the Roar, but they would not be able to match that goal difference.
Brisbane themselves travel to AAMI Park for a match up with what is likely to be a depleted Victory side on Saturday night, Kevin Muscat's men suffering fatigue having played in New Zealand on Saturday before a trip to South Korea for a midweek Asian Champions League game.
