Mirassol

Brazil

Founded 1925·Group-stage debut (2026)

Founded in 1925, Mirassol spent nearly a century in Brazilian football's shadows before one of the country's fastest recent rises: Serie D champions (2020), Serie C champions (2022), Serie B runners-up (2024) and Serie A debutants in 2025 — the same season a fourth-place finish earned them their first-ever Libertadores spot.
