Ange Postecoglou resigned as coach of the Brisbane Roar on Tuesday, two days after guiding the club to back-to-back A-League titles.
Postecoglou, 46, had been heavily linked with the vacant Melbourne Victory job in the weeks leading up to Brisbane s grand final triumph.
A National Soccer League championship-winner as a player and coach with South Melbourne, Greek-born Postecoglou is now expected to return to his home town, and take on the challenge of reviving underachieving Victory.
I would like to express my gratitude to the owners, players and football staff of the Brisbane Roar, Postecoglou said in a statement released on Tuesday.
Their commitment and belief has created history for this club.
I have been very proud to lead such an outstanding group of men, and I wish the club every success in the future.
Brisbane will make an announcement on the now-vacant role of Roar head coach on Wednesday, with Postecoglou s assistant manager, Rado Vidosic, tipped to take over.
The Brisbane Roar would like to thank Ange for his commitment to the club over the last two-and-a-half years, and the considerable role he has played in its success, Roar director Chris Fong said in a statement.
We respect how difficult this decision was for him and we wish him well in his new endeavours.
Ange s departure marks the beginning of a new chapter in the story of the Brisbane Roar, and we are committed to ensuring we have the right people in place to continue the club s legacy with further successes.
Roar came from behind to defeat 10-man Perth Glory 2-1 in controversial circumstances in Sunday s A-League decider at Suncorp Stadium.
Albanian striker Besart Berisha, the league s top scorer this season, went to ground to win a penalty deep into injury time, slotting home the spot kick to win the match for Brisbane in the 97th minute.
It was the Roar s second title triumph in two seasons after they defeated Central Coast Mariners on penalties in last year s grand final.
Postecoglou took over at Brisbane in October 2009, replacing Frank Farina. During his time in charge the Roar embarked on a 36-match unbeaten run, breaking the previous undefeated record for any code of football in Australia.
Brisbane also became the first club to retain their championship crown in the A-League era, under Postecoglou s guidance.
