The 2010–11 LEN Women's Champions' Cup was the 24th edition of the highest-level competition in women's European club water polo. It involded the champions and other top teams from European national leagues and ran from December 2010 to April 2011. The Final Four (semifinals, final, and third place game) took place in Sabadell, Spain.
Each national federation can enter up to two teams into the Women's Champions' Cup.
Seeded Federations are the federations who placed a team in the Final Four of the previous' year's competition. In 2009/10, these countries were: Greece (2), Italy, and Russia
All other federations are unseeded
Federations do not have to enter their top two teams into the Champions' Cup. If they do not think their clubs can be competitive, they can enter teams into the second-tier LEN Cup.
Format and Changes
The original format for the Champions' Cup was to have four phases:
A qualification round of 4 groups of any size played as a Round-robin tournament at the site of a host team
A preliminary round of 4 groups of 4 played as a Round-robin tournament at the site of a host team
However, there were only 13 entries, so the qualification round was cancelled, and the preliminary round will be played with 3 groups of 3 and 1 group of 4.
