São Paulo Futebol Clube is a Brazilian professional football club based in the Morumbi district of São Paulo. It plays in Campeonato Paulista, the São Paulo's premier state league, and in the Campeonato Brasileiro Série A, the top tier of Brazilian football. Despite being primarily a football club, São Paulo competes in a wide variety of sports. Its home ground is the multipurpose 67,052-seater Estádio do Morumbi, the biggest private-owned field in Brazil. São Paulo is part of the Big Twelve of Brazilian football, South America's biggest worldwide champion — with three world titles, along Boca Juniors, Peñarol, and Nacional — and one of the only two clubs that have never been relegated from Brazil's top division, the other being Flamengo.
