It will be an all-Brazilian Final in the first edition of the FIFA Club World Championship.
Corinthians of Sao Paulo meet Rio de Janeiro rivals Vasco da Gama in the Final on Friday evening, ensuring that the new silver trophy will spend the rest of the year in Brazil.
After Corinthians had booked their berth in the Final on Monday, Tuesday's games saw Vasco da Gama also qualify thanks to a 2-1 win over Necaxa of Mexico.
That left Necaxa to contest the match for third place, also in the Maracana Stadium on Friday, against Real Madrid. Despite their defeat, the Mexicans still finished with a slightly better goal tally than Manchester United, whose second-string team beat South Melbourne in Tuesday's other match.
The Corinthians - Vasco showdown is the latest round in the ongoing epic struggle for supremacy in Brazilian football between teams from the country's two largest cities. The difference is that this time, there is not just national pride at stake - but a world title.
