Lionel Messi is set to take on Neymar at the MCG in a heavyweight clash between Argentina and Brazil.
The South American giants will reportedly play next June in the SuperClasico de las Americas.
The Victorian government is expected to announce the long-planned fixture in the coming weeks, according to News Corp Australia.
The report says one of the teams will likely then play the Socceroos in a tune-up for Australia's Confederations Cup campaign in Russia.
Coach Ange Postecoglou is eager to get in a friendly match after the June 8 World Cup qualifier with Saudi Arabia at Adelaide Oval, and before the national team have to be in Russia on June 15 ahead of their first Confederations Cup game against Germany on June 19.
The date of the clash between five-time World Cup winners Brazil and two-time champions Argentina will depend on the MCG's availability during the 2017 AFL season, with matches already scheduled for June 10, 12 and 17.
Should it come off, it would pit Barcelona superstars Messi and Neymar against each other.
But they wouldn't be the only big names.
Argentina also features Manchester City pair Sergio Aguero and Pablo Zabaleta, Juventus star Gonzalo Higuain and Barcelona's Javier Mascherano, while Brazil could field Liverpool duo Philippe Coutinho and Roberto Firmino and Chelsea's David Luiz.
The nations rarely play each other outside the World Cup qualification cycle but the SuperClasico de las Americas offers a chance to fight for silverware.
Created in 2011, the match-up is the successor of the Roca Cup played irregularly between 1914 and 1976, and originally featured two games played in a home-and-away format.
Brazil won the first series 2-0 on aggregate before Argentina got revenge in 2012 via a penalty shootout.
In 2014, the format was changed to a one-match play-off at a neutral venue, won 2-0 by Brazil in Beijing.
A spokesperson for the Victorian government declined to confirm the fixture was in the pipeline, saying: "The government has nothing to add to this morning's speculation".
