Competition system

27 teams (European national domestic league champions only), playing in a tournament system, played knock-out rounds on a home and away basis. The aggregate score of both games decided the winner.
The eight remaining teams after the knock-out rounds entered a 1/4 Final Group Stage, which was played as a round-robin. The final standing was based on individual wins and defeats. In the case of a tie between two or more teams after the group stage, the following criteria were used to decide the final classification: 1) number of wins in one-to-one games between the teams; 2) basket average between the teams; 3) general basket average within the group.
The top four teams after the 1/4 Final Group Stage qualified for the Final Stage (Final Four), which was played at a predetermined venue.
