Thousands of fans lined up in the middle of the night to try to get a glimpse of the Argentina soccer team that won one of the greatest World Cup finals of all time ahead of what is scheduled to be a day of celebrations in Buenos Aires.

Members of the team, led by captain Lionel Messi, were all smiles as they descended from the plane in Ezeiza, right outside Argentina's capital, shortly before 3 a.m. Tuesday onto a red carpet that had been rolled out for the squad.

Messi was the first player from the plane carrying the World Cup, flanked by coach Lionel Scaloni, who put his arm around the captain as they walked past a sign that read, "Thank you, champions."

The players were welcomed by rock band La Mosca singing "Muchachos," a song that was written by a fan to the tune of an old song by the band and became a popular unofficial anthem for Argentine fans at the World Cup in Qatar.

The newly crowned champions of the world boarded an open top bus and several, including Messi, could be seen singing the words to "Muchachos" while they waited for everyone to get on to travel to the headquarters of the Argentine Football Association. 

The bus moved at a snail's pace as fans, many of whom were waving Argentine flags, swarmed the bus on a highway, eager for a glimpse of the players as law enforcement officers tried to keep them at bay.

Throughout the trip, Messi held on the World Cup as players waved to fans and often sang along with them.

It took the bus around one hour to travel approximately 11 kilometres from the airport to AFA headquarters, where the players were welcomed with fireworks.

They will sleep at AFA headquarters for a few hours before boarding the bus later Tuesday to the Obelisk, the iconic Buenos Aires landmark that was a sea of people Sunday afternoon after the team won the country's third World Cup, and its first since 1986.
