the same for every Brasil Big 12 team.
Palmeiras is especially obsessed with winning a global championship other than the disputed one they won at Copa Rio (played in 1951 and 1952 only) in 1951 https://en.wikipedia.org/wiki/1951_Copa_Rio
Big 12 clubs: Atlético Mineiro, Botafogo, Corinthians, Cruzeiro, Flamengo, Fluminense, Grêmio, Internacional, Palmeiras, Santos, São Paulo, and Vasco da Gama.
These are the six Big 12 teams who have won either the Interncontinental Cup or the FIFA World Club Cup
Intercontinental Cup winners
Santos 1962, 1963 (the Pelé-led best ever, IMHO, Brasilian sides)
São Paulo 1992, 1993 (Cafu-led)
Grêmio 1983 (Renato Gaúcho-led)
Flamengo 1981 (Zico-led)
FWCC winners
Corinthians 2000, 2012 (grrrr)
São Paulo 2005
Internacional 2006
that leaves these six Big 12 Brasil teams without a true global championship (although the first 3 teams listed claim one, see below)
Palmeiras (won the 1951 Copa Rio, but lost the Intercontinental Cup in 1999 and the FWCC final in 2021, (to Chels)
Fluminense (won the 1952 Copa Rio, but lost the FWCC final in 2023, they did win the Tournoi de Paris in 1976 and 1987)
Vasco da Gama (won the 1953 Torneio Octogonal Rivadavia Correa Meyer (played once, it was the successor to the Copa Rio), but lost the Intercontinental Cup in 1998 and the FWCC final in 2000, also lost the Small Club World Cup final in 1956, they also did win the Tournoi de Paris in 1957)
Atlético Mineiro (they never played in the IC, nor in a FWCC final (they did win 3rd place in 2013), they did win the Tournoi de Paris in 1982)
Botafogo (lost the Small Club World Cup final in 1952 and in 1957, never played in the IC nor in a FWCC final, they did win the Tournoi de Paris in 1963)
