Moore had asked to quit the club two days ago through Football Manager Thiago Cruzin order to secure a short-term European deal to further his World Cup 2010 ambitions.

But today chief executive Peter McLennan revealed Moore's demands for Postecoglou to be axed meant the split would now be permanent.

"During discussions with Craig over the past eight weeks he made it clear he was unhappy working under Ange Postecoglou at the club," McLennan said.

"On at least two occasions during that time Craig issued me with the ultimatum that either Ange went or he went.

"Clearly over recent weeks the club has begun to move in a new and exciting direction and the bottom line is that no individual is bigger than the club.

"It is regrettable Craig won't be a part of what we believe will be a bright future. We have complete faith in what Ange is seeking to achieve at the club and he has everyone's full support."

With Moore's departure Brisbane will now turn its attention to securing Hyundai A-League finals football this season and the recruiting program for next season, including the search for a marquee player.

McLennan added: "As a club we have always maintained we would support Craig's ambitions in regards to the World Cup, the only difference in his departure is we had hoped he would return following the tournament.

"We thank Craig for his contribution to the Roar and wish him the best of luck with his future endeavours. Like every Australian football fan we hope he has an outstanding World Cup in South Africa."

Moore was today in Dubai training withe Socceroos ahead of next week's crucial Asian Cup qualifier against Kuwait. He has been strongly linked with a move back to Scotland - where he played with Rangers - to join Perth-based St Johnstone.
