Serie A Betano

Brazil's calendar-year top flight, a single all-play-all table with relegation and Libertadores qualification.

The Campeonato Brasileiro Série A, known commercially as Série A Betano, is Brazil's top professional football division and one of the most-watched leagues in South America. Its modern format dates to 1971, and since 2006 it has featured 20 clubs playing a double round-robin, single-table season across the calendar year, typically from April to December, with every team facing every other club home and away. The champion is simply the club that finishes with the most points after all rounds; there are no play-off finals. The bottom four clubs are relegated to Série B, while the leading finishers qualify for the Copa Libertadores and Copa Sudamericana, giving almost every matchday direct stakes at both ends of the table. Palmeiras are the competition's most decorated club with 12 titles, with Santos, Flamengo and Corinthians among the other traditional powerhouses. Rivalries such as Fla-Flu, the Grande São Paulo derbies, and clashes between Corinthians and Palmeiras give the league its intense club culture, backed by some of the world's most passionate supporters. For fans following live scores, the Brasileirão offers a long, dense calendar-year season packed with title, continental-qualification and relegation battles running in parallel from the opening round to the final matchday in December.
