Bath, armed with the only maximum 20-point record in ERC tournaments this season, will secure their place in the last eight as Pool 4 winners if they defeat Agen in Saturday's Round 5 game at the Recreation Ground.
Gloucester face a demanding trip to Bordeaux-Bègles where a victory would seem them emerge on top of Pool 1while Wasps will remain favourites to qualify from Pool 3 if they continue their unbeaten run at Adams Park this season with a win over Italian visitors, Rugby Mogliano.
If Stade Francais maintain their winning ways in Pool 5, then they too will be on their way to the knockout stage, however, the Paris club will find it extremely tough when they take on French rivals, Grenoble, at Stade Lesdigiuères on Saturday.
As the pool stage reaches its conclusion, the outcome of Pool 2 remains the hardest to call. With the slimmest of margins separating Worcester and Perpignan, Worcester are currently in first place by virtue of a superior points difference as not all clubs have yet played their pool opponents twice.
However, if Worcester and Perpignan are still level at the conclusion of the pool stage when all clubs have played their pool opponents twice, then Perpignan would qualify by virtue of scoring three tries to Worcester's one in the matches between the clubs.
Vital ERC European ranking points are also at stake for Amlin Challenge Cup clubs throughout the pool and knockout stages of the tournament. A pool winner is guaranteed two ranking points, with a further two for qualification for the semi-final, and two more available for the competition winner.
The ERC European ranking points system rewards and incentivises clubs which consistently perform at the highest level in European competitions.
