Goals from Jackson Irvine and Mathew Leckie kept the Socceroos on the Road to Russia after the disappointing 1-1 draw with Iraq last week.

Postecoglou continued with his experimental back three formation despite coming under fire from fans and the media.

And at an AAP Sports Editors' conference in Sydney this morning, he doubled down on his tactics and approach...but admitted he was likely to leave the Socceroos job next year.

"I'm determined to go down the road of playing fairly aggressive, fairly adventurous football," he said today. "It may be putting results at risk at times. [But] it's not just about qualifying. 

"We have done that now. We did it in 74, 06, 10 and 14. That would be the same as a club team just wanting to make the finals every year. We should be in it to win it. 

"We need to see ourselves as a nation that can win the World Cup and see Australia conquer the world. That is my ambition."

Postecoglou said he had continued to push on with his strategy switch despite the backlash because he believed it was vital for the sport's growth.

But he concedes it could put Australia's place in Russia in jeopardy and admitted: "My tenure is likely to end in the next 12 months or so.

"In my first 11 games, we won one. But the reason I knew we would win the Asian Cup was because of the road we had taken.

"This week has been a test to see if we bunker down and just try to qualify and get everyone off our backs.

 "Where it ends up, no-one knows. There are no guarantees in sport. You can do everything right and sometimes the results just go against you.

"What seems left field, what seems like not the normal course of events, is just the way I am. Success feeds into itself. There is a manner and approach you have to take if you really believe."

Postecoglou hailed the new players coming through and stressed how important it was that the new faces encouraged others – and for them all to then push on to greater things.

"I think there is a handful of players that can play at a top level, the EPL, Bundesliga, La Liga, in the next few years," he said. "My job is to push them and not let them get comfortable or too complacent.

"Every time I have had a camp I have tried to cast the nest as far as possible. I won't want to miss anyone. Half the battle is just opportunity. That's not just in sport, that's in life. 

"Jackson Irvine is a element of that, also Trent Sainsbury and Mat Ryan. Probably in the past I would have waited a year or two until Jackson was playing in the EPL. 

"He's come along really and he's just beginning his international career but he's showing some great signs...and it encourages his contemporaries."
