Leinster have dropped down to third seed for The Champions Cup draw which will take place next Wednesday in Neuchatel, Switzerland.
The relatively new structure means League champions Glasgow (inset), Saracens and the Top-14 winners between Clermont-Auvergne and Stade Francais on Saturday will be top seeds.
The Tier-1 clubs will be completed from two of the three beaten finalists from the PRO12, Top-14 and Premiership.
Munster have a two-out-of-three chance to be drawn out as a top seed along with Bath and the losing finalists from the Top-14.
The third tier or seed will include the two clubs ranked fourth which are not in Tier 2, possibly Ulster, as well as the three fifth-ranked clubs from each league in Exeter Chiefs, Racing 92 and Leinster.
Connacht will benefit from a guaranteed first seed in The Challenge Cup with Sale Sharks and Montpellier.
