After escaping their groups in dramatic circumstances, just three days later Argentina and last-16 opponents Australia meet at Ahmad bin Ali Stadium on Saturday.
Both nations' World Cup adventures now continue into the knockout stages, following the Albiceleste's recovery from a shock opening loss to Saudi Arabia and the Socceroos' defeat of Denmark in midweek.
Having overcome a faltering start to their latest World Cup campaign, an Argentina squad fuelled by a hard-fought victory over Mexico in their second Group C fixture secured a spot in the last 16 by bettering a limited Poland side on Wednesday.
The South American champions saw talisman Lionel Messi spurn the chance to open the scoring from a contentious first-half penalty, but were ultimately rewarded for 90 minutes of dominance by leapfrogging their European opponents at the top of the group standings.
After Alexis Mac Allister - who had been promoted to the starting lineup as one of a handful of changes made by coach Lionel Scaloni - made the breakthrough only seconds after the interval, a 67th-minute strike from Julian Alvarez helped the Albiceleste to post a second successive 2-0 win.
As a result, for the 11th time in the last 12 finals the two-time world champions have progressed to the knockout phase, and they remain among many pundits' favourites to lift the World Cup trophy later this month.
While conditions will be the same for both his team and their next opponents, Scaloni has bemoaned the fact they will return to action after just over two days rest - particularly having followed such an emotionally draining route to the top of Group C. However, he knows that no excuses will be accepted by an expectant public back home in Argentina.
To combat concerns about fatigue, the Copa America-winning coach can call upon several talented players to have emerged from the fringes of his squad, such as Mac Allister, Alvarez and Benfica's Enzo Fernandez, though of course Messi still shoulders much of the creative burden.
Argentina's irreplaceable playmaker will surely be integral again, as they attempt to set up a quarter-final with either the Netherlands or United States, but he will need plenty of help from the supporting cast that put on a 36-game unbeaten streak only ended last week.
Given the gulf in stature between the two nations in football terms, it comes as no surprise that Australia have lost each of their last four meetings with Argentina - including a crucial playoff to reach USA '94 - though the Socceroos earned a 2-0 win when two very different squads clashed at last year's Tokyo Olympics.
Yet, Graham Arnold's men are riding the crest of a wave before they arrive in Al Rayyan for a date with destiny that sees them taking part in the World Cup knockout rounds for the first time since the fabled 'golden generation' of 2006.
The unfancied Socceroos defied expectations to finish second in Group D behind defending champions France, doing so only on goal difference after winning two of their three fixtures - against Tunisia and then Euro 2022 semi-finalists Denmark.
Beating the latter 1-0 at Al Janoub Stadium required both a fiercely-fought rearguard action led by Harry Souttar and goalkeeper Mat Ryan, and a wonderful winning goal from Matthew Leckie, which broke the deadlock in the 60th minute and ultimately sent them through to the last 16.
Realism is never far away from a pragmatic Australian side, largely made up of players on the fringe of things at their European clubs, so for all the euphoria their historic victory unleashed, they will be acutely aware of the step-up in class that awaits on Saturday.
Already swept aside by a fluent French team, who ran out 4-1 winners in the sides' opening fixture, Arnold's well-drilled unit will be outsiders to topple Argentina and make the final eight for the first time ever.
If they could somehow do so, jubilant scenes of fans celebrating on the streets of Melbourne in the early hours of Thursday morning would surely be matched - even surpassed - in Sydney, Adelaide and beyond.
