Champion and contenders

Pre-season favorites Corinthians captured their fourth national championship edition despite a turbulent early season and a campaign that went through 3 different head coaches. Key players Carlos Tevez, Carlos Alberto, Roger and Gustavo Nery led the team to a result of 81 points in 42 games. Despite early season turmoil, Corinthians benefited from being one of the few teams in Brazil who could afford to maintain their talent base throughout the season without having to sell key players. The legitimacy of their title was disputed late in the season due to several scandals on and off the field. As 2005 champions, Corinthians received berth into the first round of the Libertadores Cup as well as the South American Cup in 2006.

Internacional of Rio Grande du Sul executed a strong campaign, finishing with a total of 78 points. Coach Muricy Ramalho led a team with Rafael Sobis, Fernandão, and Tinga to the best performance of any team in the second half, narrowly missing the opportunity for their own fourth national title, but also securing a place in the first round of the Libertadores.

Goiás and Palmeiras were awarded pre-Libertadores qualifying matches with teams to be determined by Conmebol for their 3rd (Goiás's best ever) and 4th-place finishes.

Consolation prize

In the top middle of the pack Fluminense, Atlético/PR, Paraná, Cruzeiro, Botafogo, Santos, and São Paulo were awarded allocations in the 2006 Copa Sul-Americana; with São Paulo, who cannot participate due to Libertadores commitments, ceding their spot to 12th placed Vasco da Gama. Santos in particular saw their season nose-dive as star player Robinho was transferred to Real Madrid mid season (a similar fate encountered by Cruzeiro as striker Fred was shipped off to Lyon). Atlético/PR and São Paulo both suffered for having to dedicate their primary attention to the 2005 Libertadores Finals.

The bottom

Finishing in the bottom four and relegated to Série B for 2006 are storied franchise Atlético Mineiro as well as perennial mid-majors Coritiba, Paysandu, and Brasiliense. Série B champions and runner-up Grêmio and Santa Cruz took their place.

Mid-season transactions

While the CBF and Clube dos 13 continue to modify the league format in the hopes of decreasing the number of mid-season departures and improve the overall quality of play, the 2006 edition saw a significant number of players depart for Europe and elsewhere.
