After 6 rounds Perth Glory is standing at the 1st position, with 15 points and with goal difference 10:7. They are in great form this season, they have 5 wins in a row including Australian Cup.
Wellington Phoenix is standing at the 5th position with three wins and three losses with 9 points after 6 rounds and their main goal is to keep one of the places in play-0ff..
Those teams have already played this season and Perh G. beat them in away with 2-1
I expect an home win, but that both teams to score goal also could be a good betting option
