A total of 20 teams participate in the main competition, with 17 teams being allocated direct vacancies on the basis of ranking list for European Cup Competitions and 3 teams qualify from the qualification rounds.[1][2]
Format
League round
A round-robin format (two single round-robin tournaments held in ‘bio-secure bubbles’ at two different venues in each pool) where the 20 participating teams are drawn into 5 pools of 4 teams each. The five pool winners and the best three second placed teams among all pools qualify for the Playoffs.[3][2]
The standings is determined by the number of matches won.
In case of a tie in the number of matches won by two or more teams, their ranking is based on the following criteria:[4]
result points (points awarded for results: 3 points for 3–0 or 3–1 wins, 2 points for 3–2 win, 1 point for 2–3 loss);
set quotient (the number of total sets won divided by the number of total sets lost);
points quotient (the number of total points scored divided by the number of total points lost);
results of head-to-head matches between the teams in question.
Playoffs
A knockout format where the 8 qualified teams are each draw into the quarter-finals with the round winners advancing to the next rounds (semifinals and final). Matches in the quarter-finals and semifinals consists of two legs (home and away).
Result points are awarded for each leg (3 points for 3–0 or 3–1 wins, 2 points for 3–2 win, 1 point for 2–3 loss). After two legs, the team with the most result points advances further in the tournament. In case teams are tied after two legs, a Golden Set is played immediately at the completion of the second leg. The Golden Set winner is the team that first obtains 15 points, provided that the points difference between the two teams is at least 2 points (thus, the Golden Set is similar to a tiebreak set in a normal match).[4]
Grand finale
A single match between the winners of the semifinals in a neutral venue decides the tournament champion.[3]
