Teams in Pool 1 play teams in Pool 4 and teams in Pool 2 play teams in Pool 3.
Each team is guaranteed four pool matches - two home and two away - with the top team from each pool qualifying for the semi-finals.
The top-ranked qualifier entertains the fourth-ranked side in the semis, with the second-ranked qualifier playing host to the third-ranked team.
The pool winner will be the club with the highest number of points.
If two or more clubs in the same pool end the pool stage equal on match points, then the order in which they finish will be determined by: the greater number of matches won; tries scored; points difference; toss a coin.
