02Worth knowing
What the AIs noticed while building the list.
Internacional is the only Brazilian club to win twice at La Bombonera (2008 and 2020). That is why there are nine wins but eight clubs.
Vasco's win is only the second by a Brazilian club in a semifinal or final at La Bombonera, after Santos in 1963.
Boca has won 26 of its 39 series against Brazilian clubs, and four of the 13 it lost went to penalties.
Counts differ: 12 Brazilian wins if five friendlies from 1958 to 1971 are included, 9 official ones without them. That is why this list has nine places, not ten.
03How we counted

What Claude noticed
Only nine official Brazilian wins at La Bombonera surface in the lists I could check. Vasco is described as the eighth club to do it, and Internacional is the only club to have won there twice (2008 and 2020).
Counting only knockout ties, Vasco is the fourth Brazilian club to win at Bombonera, after Santos (1963), Paysandu (2003) and Internacional (2008). Three of the others were group games.
Boca has lost 13 series to Brazilian clubs out of 39, and four of those went to penalties (Cruzeiro 1996, Atlético Mineiro 2021, Corinthians 2022, Cruzeiro 2024), where a Bombonera result mattered little.
Boca reached this semifinal by eliminating São Paulo in the quarterfinals, 2–1 on aggregate.

Only four Brazilian clubs have won at La Bombonera in knockout ties: Santos, Paysandu, Internacional and Vasco.
Internacional is the only Brazilian club to win twice at La Bombonera in CONMEBOL competitions (2008 and 2020).
Vasco’s win was only the second by a Brazilian club in a semi-final or final at La Bombonera, after Santos in 1963.
Paysandu’s 2003 win is often called the biggest upset, but Boca still won the tie 4-2 and went on to lift the Libertadores.
