The only undefeated champion

The only undefeated champion is Internacional (counting only editions of Brazilian championships from 1971 onwards). The team from Rio Grande do Sul won the national title in 1979 without a single defeat. The only five-time consecutive champion team is Santos (1961, 1962, 1963, 1964 and 1965). Only on three occasions did the Brazilian champion not come from a capital: Guarani (1978) and Santos (2002 and 2004).
