The four Welsh sides have discovered their fate after the draws for the European competitions.
The Ospreys are Wales' sole representative in the Champions Cup after sneaking past the Scarlets on the final weekend of the season, with the other three playing in the Challenge Cup. The convoluted draw see sides in both competitions drawn into one of two pools, A and B, but pool stage fixtures will take place against just two other clubs.
In terms of ideal draws, the Ospreys was as far away from that as possible. Drawn into Tier 4 of Pool B, they will face Premiership champions Leicester Tigers and Top14 winners Montpellier home and away.
