Lionel Messi was called up on Monday to the Argentina squad due to face his new Paris Satin-Germain teammate Neymar and Brazil in a World Cup qualifier next month.
The crunch CONMEBOL encounter on September 5 will mark the first time the two icons face each other as PSG teammates, and will come less than two months after Messi inspired Argentina to a 1-0 victory over Brazil in the Copa América final.
The highly-anticipated encounter is sandwiched between two other World Cup qualifiers, with the Albiceleste playing Venezuela on September 2 and Bolivia a week later.
Brazil lead the single CONMEBOL qualifying group with a perfect 18 points from six matches, while Argentina are second with 12 points and also unbeaten.
Messi won his first international trophy in July as he helped Argentina end a 27-year wait for major silverware by upsetting Brazil at Rio de Janeiro's iconic Maracanã stadium.
The two countries' star players are yet to play alongside each other this season as both have been given an extended break by PSG following their Copa exertions.
After more than two decades playing at Barcelona, Messi is widely expected to make his PSG debut this weekend away to Reims.
Argentina coach Lionel Scaloni sprung no huge surprises in his squad, though he did recall Paulo Dybala of Juventus who joins Inter Milan's Lautaro Martínez among powerful-looking forward options, although new Barça signing Sergio Agüero misses out through injury.
