The 2023–24 LEN Champions League is the 61st edition of LEN's premier competition for men's water polo clubs. Because of the congested schedule, there's a new format this year.[1]Pro Recco are the three time defending champions.
This season, the format has undergone some changes. After one qualification round (instead of three), sixteen teams will qualify for the group stage. Because of the congested schedule, four groups of four will be played instead of two groups of eight. The top two in each group will make the quarter-finals round (also a group stage). The team that finish third and fourth will compete in the 2023–24 LEN Euro Cup knockout stage. The remaining eight teams in the quarter-finals round will play a further six matches, with the top two in each group making the final four, which makes a return.[3]
Rankings
Starting this season, LEN also started a club rankings. The top 11 best ranked countries in the new rankings are allowed to have their national champion go directly into the main round, as long as they meet requirements.[1][4]
Alongside the 11 domestic champions, the defending champions also get a spot in the main round. In the event that the Champions League defending champions won their national league, the runners-up of the national league will take the vacant spot. Although, the Italian runners-up, AN Brescia, declined the spot because they didn't want to pay the wildcard fee (which was 25,000 Euros), their spot went to the Spanish runners-up, Astrapool Sabadell).
The group winners qualify for the main round, while everyone else drops down to the Euro Cup qualifiers.
