In a snippet from an expansive interview with Fox Sports which will air tonight, Postecoglou spoke about his impending Japanese move as well as the reaction from fans and players after quitting his post as national coach.

The 52-year-old this week signed a multi-year deal with Japanese football giants Yokohama F Marinos which are part of the Manchester City football group.

Forever ambiguous, Postecoglou spoke about his journey in Australian football and an understanding of the public’s want to better comprehend why he stood down as Socceroos mentor.

But one thing is for sure, the current state the governing body finds itself in had no influence on him deciding to leave the Socceroos after helping them to the World Cup.

“No, mate, because, I guess, probably my biggest frustration is that people don’t put into perspective my journey in Australian football,” Postecoglou told Fox Sports.

“It’s been continued chaos.

“I’ve probably been involved longer than most ... a lot of people left the country and came back, I’ve been here the whole time. It’s always been sort of chaotic and you almost get used to that.

“If that was going to be a reason for me leaving, I’ve had a million reasons (to do it previously). In fact, I probably wouldn’t have taken it to start with.

“Whilst I understand people see it from the outside and say - you’re coaching your national team, that’s the highest honour - I’ve always felt that way, but at the same time after my previous experience with the national team for seven years, I really needed a purpose to take this position again because I knew what challenges were involved.

“I left Melbourne Victory after a year. I was really excited by what we were starting ... I’d signed a three year deal, it’s a big club, I felt we could create something special.

Postecoglou said in time he hoped to clarify his reasoning better.

“I understand it (people feeling let down), and I’ve had fantastic support,” he said.

“I know the way I do things sometimes challenges people and doesn’t follow a logical process but I’ve had tremendous support all along. There’s probably a reason for them to be disappointed I can’t say it’s for a/b/c but I can only be who I am.

“Part of the complexity of who I am is the personality and character I have and I can’t be false about that.

“I’d love to say - this is the reason. Some of it is personal, some of it is professional, some I don’t see the point in bringing up right now.

“I think in the context of time I may be able to sort of talk about things further, but I’ve always been ... disappointed when people try and bring the game down in the country. We’re probably world champions at that, to try and beat ourselves up as a game in this country. I always try to make sure I never do that.

“To bring up something that isn’t actually the pivotal reason but one of the reasons I’m leaving, if I don’t think it’s going to serve a purpose or help the game, I’m just not going to talk about it.”

The full 30-minute interview will be broadcast at 6.30pm EDT tonight on FOX SPORTS 501.
