With just one quarter-final place assured, Round 6 of the European Rugby Champions Cup promises to be a cracker with fireworks aplenty.
Leinster Rugby are the only team with a perfect record and certain of their place in the last eight, meaning there are seven places up for grabs this weekend.
Glasgow Warriors v Exeter Chiefs
Saturday’s action kicks off at Scotstoun Stadium as Glasgow Warriors welcome an Exeter Chiefs side desperate to push their claims for a quarter-final spot.
Reigning Aviva Premiership champions Exeter Chiefs are nine points behind runaway leaders Leinster Rugby, but a bonus point win would see them move to 19 points and would be well placed for one of three runner-up qualifying spots available.
Montpellier v Leinster Rugby
Leinster Rugby will aim to maintain their perfect record and go six from six when they travel to face Montpellier.
Leinster defeated Montpellier in the reverse fixture and will be flying high after a 55-19 win over Glasgow Warriors last weekend, while Montpellier were beaten 41-10 by Exeter Chiefs in Round 5.
Clermont Auvergne v Ospreys
Clermont Auvergne head into Round 6 in control of Pool 2, but their guests Ospreys are just there points behind ahead of Saturday’s crunch clash.
Pool 2 remains a three-horse race with defending champions Saracens only five points adrift, but a win for Clermont Auvergne seals their fate in the last eight draw, but would leave Ospreys depending on a Saracens loss to keep their hopes alive.
Saracens v Northampton Saints
Reigning kings of Europe Saracens welcome Northampton Saints to Allianz Park on Saturday knowing their title defence hangs in the balance.
Saracens can only aim for a bonus point win and hope other results above fall in their favour to ensure they at the least get a shot at a runner-up spot which gives them a pass through – defeating Northampton Saints, given the 57-7 win in Round 1, should be the easy part of the bargain.
Benetton Rugby v Bath Rugby
Bath Rugby travel to the Stadio di Monigo on Saturday evening hoping to do all they can to throw their hat in the mix for a quarter-final spot as they take on Benetton Rugby.
Bath Rugby stand five points behind Pool 5 leaders RC Toulon ahead of the final round, but with them facing second-placed Scarlets, a bonus point win should see Bath Rugby elevated to second ahead of either RC Toulon or Scarlets and thus put them in contention.
Scarlets v RC Toulon
Scarlets host three-times European champions RC Toulon at the Parc y Scarlets on Saturday with the Welsh region looking to steal Pool 5.
Just one point separates the Pro14 side from the French heavyweights, whom they lost 21-20 to at the Stade Felix Mayol earlier in the competition, but a win would see them clinch Pool 5 and a quarter-final spot should they prevail in Llanelli.
Leicester Tigers v Castres Olympique
Racing travel to Welford Road for a Sunday dinner affair with Leicester Tigers knowing the remain in a three-horse race in Pool 4.
Leicester Tigers are the only side definitely out of the running in Pool 4, with Racing just a point behind leaders Munsters.
Munster Rugby v Castres
Pool 4 leaders Munster Rugby welcome third place Castres to Thomond Park on Sunday as the battle for last eight spots reaches a climax.
Munster lead Castres Olympique by four points behind, and a win is the only result which keeps the Irish province’s fate in their own hands.
La Rochelle v Harlequins
In another where the top three can all conceivably make the knockout stages, La Rochelle will do battle with the already eliminated Harlequins in France.
La Rochelle are a lone point behind leaders Ulster Rugby and have the easiest draw, albeit Harlequins will be boosted by their thrilling comeback win against Wasps last weekend.
Wasps v Ulster Rugby
Ulster Rugby will travel to Coventry’s Ricoh Arena on Sunday hoping they can wrap up Pool 1 with a win over Wasps.
Quarter-finalists last season, Wasps are still in contention themselves, but they are five points behind Ulster Rugby, who did also win the reverse fixture 19-9 in Round 1 – the very first game of the competition.
