Lionel Messi and Argentina will be targeting the country's 23-year title drought when the Copa America Centenario kicks off on Friday after a troubled build-up marred by corruption allegations which threatened to derail the event.
One hundred years after Uruguay clinched the inaugural four-team South American championship in Argentina, 16 teams from across the Americas are gathered in the United States for a special one-off edition of the tournament.
The three-week festival of football gets under way at the Levi's Stadium in California on Friday, when the United States face Colombia at the home of the San Francisco 49ers American football team.
The tournament will conclude with a final at New Jersey's MetLife Stadium in East Rutherford on June 26, drawing a line under what is arguably the biggest tournament held in the United States since the 1994 World Cup.
Billed as a celebration of football across the Americas, 10 South American teams and six teams from the CONCACAF (North America, Central America and the Caribbean) region make up the field.
For organisers, the mere fact that the tournament is taking place at all is something of a triumph.
For several months last year the Copa faced an uncertain future after the arrest and indictment for corruption of several officials from South America and CONCACAF responsible for dreaming up the tournament.
When plans for the tournament were launched at a glitzy event in Miami in 2014, CONCACAF President Jeffrey Webb stood proudly alongside South American federation (CONMEBOL) chief Eugenio Figueredo.
"The American continent may have been discovered in 1492, but I can't imagine a better way to unite this continent than with football," Webb said.
Yet if prosecutors have their way, both men may soon be united behind bars.
Webb and Figueredo were among several officials arrested in Switzerland in May 2015 as part of the US-led corruption investigation which ultimately led to the sensational downfall of FIFA President Sepp Blatter.
With impeccable timing, Webb is due to appear in a New York courtroom on Friday -- the day of the opening match -- to face sentencing for his role in the scandal.
