UEFA’s club competitions have long prioritized sporting merit, offering every domestic club in Europe the opportunity to compete at a continental level. This inclusive approach has been central since the organization's early days, seen in tournaments like the UEFA Champions League and Women's Champions League, as well as the newer UEFA Conference League introduced to complement the men's competitions.
Starting with the 2024–27 men's club competition cycle, UEFA is making its most significant format changes since introducing group stages to the Champions League. Instead of traditional group stages, each of the three men’s competitions—the Champions League, Europa League, and Conference League—will adopt three new leagues followed by knockout rounds. Each league will feature 36 teams, four more than before.
The new format aims to increase the number of meaningful fixtures, enhance competitive balance, and give fans more opportunities to watch top clubs face a broader range of opponents. UEFA emphasizes continuous evolution to benefit clubs, players, and spectators.
Currently, over 700 men’s and women’s clubs from 52 national associations participate in UEFA competitions. The expansion and format adjustments aim to build on this by ensuring greater access and competitive opportunities across Europe.
