In-demand Ange Postecoglou's future should be revealed within the next week - and everything points towards him being unveiled as Melbourne Victory's new A-League coach.On Sunday, Postecoglou will attempt to win back-to-back grand finals with Brisbane Roar.Then he is expected to leave the Roar and join the Victory on a long-term deal.Indications are that will be within days of the Roar's championship decider, and arrangements are in place for a possible announcement in Melbourne next week.All involved are keeping quiet about what will follow Sunday's grand final in Brisbane.Postecoglou has batted away questions for more than a fortnight about whether he will join the Victory, but tellingly has not denied it.Victory officials were tight-lipped about Postecoglou's looming appointment at the club's business lunch in Melbourne on Friday - mindful of the coach's grand final involvement.Curiously Victory chairman Anthony Di Pietro, who usually addresses the crowd at the well-attended Victory In Business functions, did not make a speech on Friday.But the exciting prospect of Postecoglou joining the Victory after a miserable season was the talk of the function regardless.Unlike last season as the Victory went on a signing spree despite not having a coach following Ernie Merrick's sacking, they have signed just two players and released two since missing the finals.Gold Coast fullback Adama Traore and Central Coast defender Sam Gallagher are on their way to the Victory, while veterans Rodrigo Vargas and Tom Pondeljak have left.That would suggest the club is waiting on Postecoglou to first sign on the dotted line, then roll out his wishlist of players to carry out the expansive style of football which has become his trademark at the Roar.Victory midfielder Grant Brebner admits he's a fan of how Brisbane play but believes their Asian Champions League commitments could allow rivals Perth Glory to cause an upset at Suncorp Stadium on Sunday.Brebner said the Victory's grand final loss two years ago while juggling ACL commitments and A-League finals showed how difficult it can be."Brisbane certainly have an interesting way of playing, unique to the A-League," he said at the Victory In Business lunch."Under Ange Postecoglou over the last couple of years, they're not only winning games, they're winning games in style."... I would actually tip Perth because I feel the Asian Champions League does take a toll on bodies."Melbourne Victory's players return to training on May 1 ahead of a friendly against Greek champions Olympiakos at Etihad Stadium on May 19.For Postecoglou - of Greek heritage and a two-time championship-winning coach at Greek-backed NSL club South Melbourne - it would be an ideal welcome home and first game in charge of the Victory.
