In a true winner-takes-all match, the scoreless draw in San Pedro Sula means there is everything to play for tonight in Sydney.

In many ways, it was a disappointing result for the Roos, who dominated play, but as has been the theme of their campaign, wastefulness in front of goal meant they came away empty handed.

And they will want to fix this quick, because they know anything less than victory tonight will be curtains for their Russian dreams.

Even coach Ange Postecoglou admitted finishing was something they needed to work on.

“It’s the hardest part of our game.”

Further complicating matters will be the 11 men Postecoglou decides to start.

While far from clinical, the Socceroos last week looked slick, creating chances and denying the Hondurans any kind of fluency.

The performance may have been enough to convince Postecoglou to stick with a tried and tested formula, but the quality he has on the bench may cause a number of headaches.

Stalwarts Mark Milligan, Robbie Kruse and Mathew Leckie are all available for selection, while Tim Cahill has declared himself ready to go after missing the first leg through injury.

Of the likely changes, Jackson Irvine looks most likely to make way for vice-captain Milligan while Tomi Juric may be dropped for Cahill or Tom Rogic.

Less certain are the wing backs.

Aziz Behich put in a stellar performance while Wanderers defender Josh Risdon was solid in his defensive duties.

But with the Socceroos chasing goals, Postecoglou may opt for more attacking-minded wing backs in Leckie and Kruse.

The Hondurans will welcome back 21-year-old dynamo Alberth Elis and captain Maynor Figueroa.

Their coach Jorge Luis Pinto has been highly critical of the Socceroos, perhaps even verging on the edge of paranoia.

He accused the Socceroos of “spying” on the Honduras training session with a drone, which was later found to be from a local family, rather than a nefarious act by any Australian official.

But everything is pointing to an Australian victory tonight.

The Australians arrived in Sydney around 24 hours before their opponents on a million dollar chartered Qantas flight, equipped with massage tables and high-tech anti-fatigue glasses.

They will play at a stadium they are intimately familiar with in front of a boisterous and expectant home crowd.

They comprehensively outplayed their opponents in the first leg, even if they have nothing to show for it.

They have the chance to write their names into the record books and inspire a generation of young Australian footballers.

They would and should be confident of a result, but will have to be wary of complacency. A single lapse in concentration can undo years of work.

A single lapse in concentration can turn Uruguay 2005 to Iran 1997.
