relegated to Série B of the following year and replaced by 2 promoted teams to reduce the number of teams to 26. From 2001 onwards, due to the busy schedule in the first semester in Brazil, teams playing in the Copa Libertadores have not been allowed to participate in the Copa do Brasil in the same year. 2002 Campeonato Brasileiro Série A Same formula down to 26 teams with 8-team playoffs. Again the 4 worst teams were relegated and replaced by 2 promoted teams to reduce the number of teams to 24. Palmeiras and Botagogo relegated for once without major rescue operation. Both would be promoted back in 2003 on normal field results. In this sense this was a major event as the change of system in 2003 could have provided in the past more-than-enough arguments for a "virada de mesa" (i.e. table turnaround, meaning under-the-table combinazioni). The final incarnation with the introduction of the full round robin system. 2003 Campeonato Brasileiro Série A The league featured 24 teams playing for the 1st time in the full round-robin system (called in Brazil "pontos corridos", i.e. running points), which is used in other major leagues. The formula was judged anti-Brazilian as it abandoned the cup-style system but was deemed necessary as this system was considered as the playoffs were not rewarding the more organised clubs with consistent season performance. Since then, the league has continued to follow the full round-robin system till today. 2004 Campeonato Brasileiro Série A This season featured 24 teams playing in full round-robin system, similar to the previous year, yet 4 worst teams were relegated and replaced by 2 promoted teams to reduce the number of teams to 22. 2005 Campeonato Brasileiro Série A This season featured 22 teams, yet again 4 worst teams were relegated and replaced by 2 promoted teams to reduce the number of teams to 20. However, 11 matches of the 2005 competition were annulled due to a match-fixing scandal and had to be replayed. 2006 Campeonato Brasileiro Série A Since 2006 till today, the league has featured 20 teams with 4 teams to be relegated at the end of the season and to be replaced by 4 promoted teams from the 2nd division, thus probably increasing competitiveness and chances of Clube dos 13 teams being relegated (up to this point only Grêmio, Fluminense, Palmeiras, Vasco, Corinthians, Botafogo and Atlético Mineiro experienced it).
