BUENOS AIRES - Millions of ecstatic fans are expected to cheer on their heroes as Argentina's World Cup winners led by captain Lionel Messi began their open-top bus parade of the capital Buenos Aires following their sensational victory over France.
Throngs of revellers wearing the national team's blue and white replica shirts and draped in flags sang, danced and set off fireworks, with many camping out all night to secure spots along the planned route.
After arriving home from Qatar in the early hours of the morning, the players set out from the Argentine Football Association (AFA) training complex on a 30-kilometre journey to the Obelsik monument in the centre of the city.
They were given a taste of what was to come on when tens of thousands of people lined the route from the international airport, where they landed at 2:40 am, to their brief overnight stop.
"Good morning," wrote Messi on his social media accounts, alongside a picture of him lying in bed hugging the World Cup trophy at the AFA complex, where the team spent the night.
Tuesday has been declared a public holiday for the celebrations.
Argentina won the final in Qatar 4-2 on penalties after a rollercoaster 3-3 draw for their first world title in 36 years.
Messi, who scored twice in the final, was the first player to emerge from the plane, holding the World Cup aloft, with coach Lionel Scaloni right behind him.
Forward Julian Alvarez, a revelation in Qatar with his four goals, was one of the next players out of the Aerolineas Argentinas Airbus A330.
A picture of Messi was emblazoned on the plane's tail with the words: "one team, one country, one dream" on its side.
The players made their way from the plane along a red carpet to a white open-top bus with the words "world champions" as their World Cup theme song "Muchachos" by ska band La Mosca blared.
The party that began after Sunday's final is now set to climax with the players' parade through the capital.
