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.
