Melbourne Victory coach, Ange Postecoglou, says his club has unfinished business heading into Friday night's elimination A-League final with Perth, but he's got no problem with holding the underdog tag. "Maybe people are underplaying how good we are but that's fine with me as well, I'd rather go in there with people underestimating us than thinking we're going to take it all before us. Kick off is scheduled for 7.30 pm at Etihad Stadium in Melbourne on Friday.
