The first phase is a regular season, in which the competing teams are drawn into three groups, each containing eight teams. Each team plays every other team in its group at home and away, resulting in 14 games for each team in the first stage. The top 5 teams in each group and the best sixth-placed team advance to the next round. The complete list of tiebreakers is provided in the lead-in to the Regular Season results.
The surviving teams are divided into four groups of four teams each, and again a round robin system is adopted resulting in 6 games each, with the top team advancing to the Final Four. Tiebreakers are identical to those used in the Regular Season.
This was the last season in which teams advanced directly from the Top 16 to the Final Four. A quarterfinal round was introduced in the 2004-05 season.
The culminating stage of the Euroleague in which the four remaining teams play a semifinal match and the winners of those advance to the final. The losers play in a third-place playoff. The team which is victorious in the Final will be Euroleague champion.
Each Top 16 group included one team from each pool. The draw was conducted under the following restrictions:
No more than two teams from the same Regular Season group can be placed in the same Top 16 group.
No more than two teams from the same country can be placed in the same Top 16 group.
If there is a conflict between these two restrictions, (1) will receive priority.
Another draw was held to determine the order of fixtures. In cases of two teams from the same city in the Top 16 (Panathinaikos and Olympiacos, Efes Pilsen and Ülker) they were scheduled so that every week only one team would be at home.
