It will be tough for Australia even with the best preparation. 

Other nations, such as China, are pouring massive resources into the campaign with former Socceroos coach Guus Hiddink in charge. 

Similarly, Vietnam is surging ahead off the back of a clear strategy and investment, while host nation Thailand proved to the Socceroos how improved they've become (though last month concerns were raised over the slow progress of works at the Thai stadiums with some warning that the country could lose its rights to host the showpiece event).

At this stage, the Olyroos will take the majority of players from A-League clubs.

It will also test overseas clubs such as Celtic, the home of winger and attacking threat Daniel Arzani who will be key to Australia's chances. 

After missing the tournament since 2008, this is Australia’s chance to finally get back on the big stage.

“You see the exposure players get at that level and look at previous tournaments," Maloney added. 

“The Olyroos played against Messi and Aguero in 2008 and prior to that our junior national teams were playing against the best in the world.

“Australia has to support the junior national teams,” he stressed.

“I understand the clubs’ point of view, even the coaches at those clubs who will be judged on results and they may have their best players missing.

“It’s not easy. But at the end of the day, it’s important for Australia to be back on the world map."

The Olyroos will be back in action next month against New Zealand as preparations continue before the A-League kicks off.

They’ll turn out at WIN Stadium in Wollongong on September 6 and Campbelltown Stadium on September 9 under coach Gary Van Egmond, who'll take temporary control. 

“The boys did a great job in Cambodia in March to qualify for the 2020 AFC U23 Championship,” Arnold said.

“Now it’s important that we get them together regularly in the lead up to January so that they are as prepared as possible to achieve the target of earning a place at the Olympics.”
