Champions Cup permutations: Everything you need to know about the final pool matches
The European Champions Cup pool stage will conclude this weekend, with four quarter-final places up for grabs after Munster, Saracens, Leinster and Clermont Auvergne progressed with one game to spare.
Here is a look at the final weekend permutations.
Twice European champions Munster have already won the group, and victory over Racing 92 in Limerick on Saturday would secure a home quarter-final. Glasgow will also reach the knockout phase if they beat Leicester at Welford Road, securing one of three best runner-up spots across five pools. Leicester and Racing are out.
Wasps, Champions Cup semi-finalists last season, will progress either as group winners or runners-up by seeing off already eliminated tournament minnows Zebre in Italy. Toulouse or Connacht, who clash in France, are also set for a quarter-final place, depending on Sunday's outcome at Stade Ernest Wallon.
Champions Cup holders Saracens have booked a quarter-final place, and victory over Allianz Park visitors Toulon on Saturday would confirm a home tie. A Toulon triumph would put them through for the sixth time in seven seasons, but a losing bonus point might also be enough, depending on results elsewhere. Scarlets and Sale are out.
Leinster head to Castres on Friday, having already secured quarter-final status, and a home tie is now their objective. Castres and second-placed Montpellier are still in the last-eight hunt, and a bonus-point victory for Montpellier at home against Northampton might be enough.
French heavyweights Clermont Auvergne won the group one round inside the distance, and they will clinch a home quarter-final by beating Stade Marcel-Michelin visitors Exeter on Saturday. The Chiefs could still go through, but realistically, they would need an unlikely five-point maximum at Clermont's expense.
POSSIBLE QUARTER-FINALISTS: Munster, Wasps, Saracens, Leinster, Clermont Auvergne, Toulouse, Glasgow, Toulon.
