This nation had a national holiday to welcome back the victorious squad and leader Lionel Messi.
Following the team's exciting penalty shootout triumph over France on Sunday in Qatar, hundreds of thousands of supporters are anticipated to fill the city streets on Tuesday for the celebration parade.
According to state media outlet Télam, the players will initially spend the night at the Argentine Football Association's practice facility.
Before the squad arrived, large fans camped overnight at the training facility, as shown in images of spectators pouring out of parked automobiles on the premises.
While others lounged in picnic chairs near coolers, some spread out on blankets on the grass.
Following Argentina's thrilling victory against France, there have been many days of constant celebration in the nation and among supporters abroad. The team's eagerly awaited homecoming continues this.
Before the arrival of the national men's team in Buenos Aires, supporters of Argentina wave flags outside the training facility.
The greatest World Cup final of all time featured a matchup between superstars Messi and Kylian Mbappé on the field.
While Messi, 35, was playing in his final World Cup game and attempting to capture the trophy that had evaded him for so long, Mbappé was representing France in the tournament in Russia and defending their victory from last year.
France came back in the second half to draw the game at 2-2 and force extra time after Argentina gained an early lead in the first half.
Messi's second goal of the game gave his team the lead again, but Mbappé's second penalty gave him his hat-trick and forced a penalty shootout, which Argentina won after France missed its first two attempts.
Following Argentina's first World Cup victory in 36 years, hundreds of thousands of spectators flocked to Buenos Aires, overflowing the main 9 de Julio Avenue.
Videos shared on social media showed happy supporters waving the Argentine flag while atop street poles, while others on the ground danced, sang, and yelled.
The Argentine team's victory was extremely emotional, and Messi's place among soccer greats with late World Cup champion Diego Maradona of Argentina and Brazilian Pelé was solidified.
“I cannot believe that we have suffered so much in a perfect game. Unbelievable, but this team responds to everything,” said Argentina coach Lionel Scaloni after the match, according to Reuters.
“I am proud of the work they did,” he added, fighting back tears as he was embraced by his players. “I want to tell people to enjoy, it’s a historic moment for our country.”
