Notes
Round and draw dates
The schedule of the competition was as follows.
Draw
The draw was held on 9 July 2021 in Barcelona, Spain.
The 20 teams were drawn into two groups of 10, with the restriction that teams from the same league could not be drawn against each other, except when there were more than two teams from the same league participating in the regular season. For the draw, the teams were seeded into 10 pots, in accordance with the Club Ranking, based on their performance in European competitions during a three-year period and the lowest possible position that any club from that league can occupy in the draw is calculated by adding the results of the worst performing team from each league.
The fixtures were decided after the draw, using a computer draw not shown to public, with the following match sequence:
Note: Positions for scheduling do not use the seeding pots, e.g., Team 1 is not necessarily the team from Pot 1 in the draw.
There were scheduling restrictions: for example, teams from the same city in general were not scheduled to play at home on the same round (to avoid them playing at home on the same day or on consecutive days, due to logistics and crowd control).
Regular season
The 20 teams were divided into two groups of 10 teams each. In each group, teams played against each other home-and-away in a round-robin format for a total of 18 games played by each team. The top eight teams from each group advanced to the playoffs, while the last two teams from each group were eliminated. The regular season started on 19 October 2021 and ended on 6 April 2022.
