What’s the European Champions Cup format in 2021-22?
The 2021-22 European Champions Cup kicks off in December and runs through until the end of May.
Toulouse triumphed last season, beating La Rochelle 22-17 to claim their fifth European title. They then went on to do the double by winning the Top 14.
There is a new format this season with four pool rounds followed by a two-legged round of 16. Here is what you need to know.
How will the European Champions Cup format in 2021-22 work?
The 2021-22 European Champions Cup will have a pool stage followed by a round of 16, quarter-finals, semi-finals and a final.
There are two pools, A and B, made up of 12 teams each from the Gallagher Premiership, Top 14 and United Rugby Championship.
Each side will play four games in the pool stage, two home and two away, and have been drawn against opponents from outside their own leagues. Then the top eight teams from each pool will go through to the round of last 16.
If a team has to forfeit a fixture due to Covid-19, like Scarlets and their opening game against Bristol, the opposition are awarded a 28-0 victory.
