A largely uneventful contest in Saudi Arabia looked to be heading for penalties between the two sides, who had beaten the hosts and Iraq respectively in their first games.
Find out how all of the action unfolded courtesy of Sports Mole's minute-by-minute coverage below.
The latest edition of this South American El Clasico will be played in the unfamiliar surroundings of Saudi Arabia as part of the grandiosely-named Superclasico mini-tournament, which also includes the host nation and Iraq - rather more low-profile footballing nations than these two.
We will have a look both these nations in a moment, but first let's check out the team news...
The five-time champions were tipped as the pre-tournament favourites going into Russia 2018, but they only made it as far as the quarter-finals before being knocked out at the hands of even third-place Belgium.
Brazil's campaign had got off to an underwhelming start when they drew 1-1 with Switzerland in their group opener, but subsequent wins over Costa Rica, Serbia and Mexico without conceding had many still tipping them to go all of the way and lift the trophy.
Argentina are by far the biggest threat they have faced since that, though, even if La Albiceleste are missing a host of their key players tonight. One which note, they have finally provided their team news...
Tite has usually switched between the pair as the leading striker, but here he opts for both players which effectively costs Manchester United midfielder Fred a place in the team as Philippe Coutinho drops deeper.
Neymar was not on the scoresheet against Saudi Arabia, but he did claim the assist for both goals and tonight will be looking to notch his 60th international strike in what is his 94th appearance for his country.
Should he manage it then he would be just the 26th player in international football history to reach the 60-goal mark, and the third Brazilian after Pele and Ronaldo.
Coutinho drops into a deeper role to accompany his clubmate Arthur, who comes into the team in place of Renato Augusto. The trip is completed by Casemiro, who is the only member of the midfield to retain his place from the win over Saudi Arabia.
In front of him there are three changes to the back four as Marquinhos is the only player to keeper his place, with Danilo, Miranda and Filipe Luis all coming into the team in place of Fabinho, Pablo and Alex Sandro.
Lionel Messi in particular is a big miss as he considers his international future, but Argentina are now looking to give youth a chance ahead of the 2022 World Cup and that explains the inexperience in their squad for this game.
Indeed, both players are still goalless at international level, with Dybala having drawn blanks in all of his 15 Argentina games and Icardi without a goal in his five. Icardi was the joint-top scorer in Serie A last season, but was still left out of the Argentina squad for the World Cup.
No other player in the squad has scored more than one, while in terms of experience it really is stark how little Argentina have. Only three of the 28-man squad named for his double-header have won 20 or more caps for their country, while as many as 19 have won fewer than 10.
There is plenty of change around the Manchester United keeper, though, with Argentina bringing in seven new faces from their rout of Iraq last time out.
Jesus gave Brazil the lead just before half time, but it took until the 96th minute for them to make it safe through Sandro, despite Saudi Arabia seeing their goalkeeper sent off in the 85th minute.
Neymar was on the scoresheet in both of those games, with Firmino adding the second against USA and Richarlison (2), Coutinho and Marquinhos getting in on the act against El Salvador,
Brazil have kept 11 clean sheets in their last 13 matches - conceding only three goals in that time - while looking back over Tite's entire reign he has kept 22 clean sheets in just 29 games, conceded only eight.
Tite has done a fine job since taking over what was a team in turmoil following their 2016 group-stage exit from the Copa America, which came just two years after the debacle of a home World Cup which saw them hammered by Germany in the semi-finals.
The sense is that Argentina have a much bigger rebuilding job to do than Brazil, though, with many of their star players reaching the age of 30 and beyond without having achieved the trophies which their talent deserves at international level.
Lionel Scaloni is the man who has been charged with leading that, although he is still only a caretaker boss as the Argentine FA search for a permanent replacement for Jorge Sampaoli. Victory tonight would certainly force Scaloni's name further into the reckoning.
La Albiceleste have eased to victories over Guatemala and Iraq since the World Cup, while they also drew 0-0 with Colombia last month in the only game against non-minnows of the international game since this summer's tournament.
There were also three more different names on the scoresheet in the triumph over Guatemala, so there does appear to be more goals throughout the team in this fledgling new Argentine era, although the ones on which the burden falls most heavily - Icardi and Dybala - have so far failed to live up to it.
Argentina have won more games than they have lost in that time, but only just with five wins, two draws and four defeats in their last 11 matches stretching back to November.
Lionel Scaloni joked in the buildup to this match that he would park the bus, but that may not actually be too far from the truth considering the attacking talent at Brazil's disposal. Another clean sheet for Argentina tonight would make it four on the bounce for the first time since June 2014.
La Albiceleste were perhaps a little unfortunate in that their two defeats came at the hands of the two finalists, but they also failed to beat Iceland and did not really deserve to make it any further than they did.
This may be a friendly in name, but there is nothing friendly about these clashes and expect both teams to go for the win tonight. Brazil appear to have the far superior quality, though, and the strength of their starting XI looks ominous for Argentina.
SPORTS MOLE SAYS: Brazil 2-0 Argentina
However, the most recent contest between the two sides did go the way of Argentina, with Gabriel Mercado scoring the only goal of the game in June of last year - one of only two defeats suffered by Tite as Brazil boss.
They have enjoyed a mixed record in recent meetings too, with the last 10 yielding four wins apiece and two draws.
Remarkably, Argentina have not strung together back-to-back wins over their greatest rivals since 1963.
BRAZIL STARTING XI: Alisson; Danilo, Marquinhos, Miranda, Filipe Luis; Casemiro, Arthur, Coutinho; Neymar, Firmino, Jesus
ARGENTINA STARTING XI: Romero; Saravia, Otamendi, Pezzella, Tagliafico; Paredes, Battaglia, Lo Celso; Dybala, Icardi, Correa
The South American El Clasico between Brazil and Argentina is yet to live up to its billing, with chances at a premium during the goalless opening 45 minutes.
It was poor marking from Argentina as they left the defender open inside the area to collect Casemiro's cross, with his first touch setting up the second for a shot at goal which Otamendi needed to nod off the line.
There was also a nervy moment for Brazil keeper Alisson, who was almost caught in possession by Correa just in front of his own line but narrowly survived by getting the ball away as a sliding challenge came in.
It is dreadful marking from Argentina from the corner, with Miranda being left completely free inside the six-yard box without having to move at all. Neymar picks him out with his corner, and it is a simple enough headed finish.
It makes it four wins from four for Brazil without conceding a goal since the World Cup, whereas Argentina are beaten for the first time under caretaker boss Lionel Scaloni.
Thank you very much for joining Sports Mole for tonight's friendly as Brazil strike late to beat fierce rivals Argentina in Saudi Arabia. I will leave you with our match report, and be sure to stick around for reaction too.
From me, though, it is goodbye for now!
