The competition format was also revamped. A total of 48 clubs participated, down from 54 in the
previous year's competition. The competition was jointly organized by
Euroleague Basketball Company and
FIBA Europe. As a result,
Benetton Treviso automatically qualified to the group stage, while
Benetton Fribourg advanced to the second qualification round where they met
Kalise Gran Canaria.
Second preliminary round The second preliminary round, also organised by
FIBA Europe, also featured 16 teams, with the eight winners from the first preliminary round joined by eight automatic qualifiers to that phase. As in the first preliminary round, matches were two-legged and decided on aggregate score, with the winners advancing to the Eurocup regular season and the losers parachuting into the EuroChallenge. Matches were played from November 4 to November 11.
Regular season Thirty-two teams—24 automatic qualifiers and the eight survivors of the second preliminary round—entered the Regular Season. From this point onward, the competition is organised by
Euroleague Basketball Company. The teams were divided into eight groups of four teams each, with each group playing a double round-robin schedule. The first and second-place teams in each group advanced to the Last 16. Regular Season matches were held from November 25, 2008 until January 13, 2009.
Last 16 For the first time in the history of the competition, a second group phase was played. The survivors of the Regular Season were divided into four-team groups, each playing a double round-robin schedule. This phase has a direct analogue in the top-tier
EuroLeague, which conducts an identical group phase, the Top 16, at the same stage of the competition. As in the EuroLeague Top 16, the first- and second-place teams in each group advance to the next phase. However, unlike the EuroLeague, which conducts a separate quarterfinal round before its Final Four, the Eurocup sent its surviving teams into a single knockout tournament, the Final Eight. Last 16 matches were played from January 27 to March 10, 2009.
Final eight Like the Euroleague Final Four, this was a knockout tournament, conducted in one-off matches, held at a single site. The semifinal losers played a single match for third place, and the semifinal winners played a single match for the Eurocup title and an automatic place in the 2009-10 Euroleague. This phase was carried over from the prior ULEB Cup format. Matches were played from April 9 through April 12. This was the last season for the Final Eight format. From
2009–10 onward, a quarterfinal round has been introduced, consisting of two-legged ties between a group winner and the runner-up from a separate group, with the winner of each tie determined on aggregate score. The quarterfinal winners will advance to the Eurocup Finals, with one-off semifinals followed by a one-off final. == Preliminary rounds ==
