Format
The tournament is played in six stages, with two teams playing a two-legged tie in each stage. In the first two rounds, if the away team wins the first match by at least a 2-goal difference, it will move towards next round. The away goals rule is also used in the Copa do Brasil. The winner will qualify to the 2010 Copa Libertadores, which prevents them from participating in next year's Copa do Brasil.
