The EPCR raffled the groups of the Champions Cup from Europe 2021/2022. Twelve teams were distributed per zone (A and B) and there in each zone four groups of three casts were formed.
First, the teams were arranged between Tier 1 and Tier 4, depending on the classification in their respective local leagues. Then, Zones A and B were drawn, which were defined by the 12 teams in each of them.
The 12 teams will face those of Tier 1 vs. Tier 4 and Tier 2 vs. Tier 3. Teams from the same country could not face each other in this first instance.
After everyone faces off against these rivals, the 8 best classified from each zone will be defined and those teams will go on to play the 16th final.
Top 14 champion and Champions Cup defender Toulouse will play Cardiff Blues and Wasps. While runner-up La Rochelle will play Bath and Glasgow. Harlequins, the Premiership champion, will face Castres and also Cardiff Blues.
