Santos and São Paulo) and Rio Grande do Sul (Caxias do Sul and Porto Alegre). Rio de Janeiro is the only city with more than two champion clubs (Flamengo, Fluminense and Vasco da Gama). Format The competition is a single elimination knockout tournament featuring two-legged ties. In the first two rounds, if the away team wins the first match by 2 or more goals, it progresses straight to the next round avoiding the second leg. The away goals rule is used in the Copa do Brasil, which is an unusual feature when compared to other South American competitions (the Copa Libertadores did not adopt this rule until 2005). However, the away goals rule is not applied if both teams are from the same city. Since the tournament's creation in 1989, the winner of the tournament qualifies for the next year's Copa Libertadores de América. Eligible teams The eligible teams to compete in the Copa do Brasil are the previous year's Copa do Brasil champion, the 70 best-placed clubs in the state championships (in which the number of spots per state range from one to five clubs), the top six clubs from the previous year's Campeonato Brasileiro Série A, the Copa do Nordeste (Northeast Cup) champion, the Copa Verde (Green Cup) champion, the ten highest-ranked clubs in CBF's ranking not already qualified, and two of the following: the Brazilian champion of the most recent Copa Libertadores (if there is one), the Brazilian champion of the most recent Copa Sudamericana (if there is one), the 7th place team of Campeonato Brasileiro Série A, or the champion of Campeonato Brasileiro Série B. The 7 Brazilians teams in the Copa Libertadores da América, the best placed teams in the previous year's Série A and Série B (or the champion of Copa Libertadores and/or Copa Sudamericana, if it is a Brazilian team) and Copa do Nordeste and Copa Verde's Title Holders will join the Copa do Brasil directly in Round of 16. History The Copa do Brasil was created in 1989 to appease the state soccer federations with fewer large and traditional clubs on the national stage, whose representatives would hardly have the opportunity to face big clubs during the year. This concern arose after a decrease in the number of participants in the 1987 Campeonato Brasileiro, when 13 of the biggest clubs in Brazil broke away to form the Copa União (Union Cup) in
