Preview: European Champions Cup, Round Six
ONE LAST CHANCE: It promises to be a tension-packed weekend in what many regard is perhaps the most hotly contest season.
Every team still involved has plenty to play for and this is always one of the best weekends in the global rugby calendar, with a fair share of crazy results always being delivered.
We first look at each pool.
Pool One: If keeping it simple in such a superbly congested Round Six is difficult, the straightforward message for Ulster (17 points) who travel to Wasps (12 points), and for La Rochelle (16 points) who host Harlequins, is that both need to win. What is certain, is that a victory for Ulster at the Ricoh would guarantee them a place in the last eight come what may. Remember too that Wasps are not out of it … which all suggests that Sunday afternoon might be a bit of a roller coaster.
Pool Two: This pool always had the whiff of death about it and now we have the TOP 14 champions and the tournament holders fighting for survival. Clermont (18 points), who have been hit by a host of injuries, need to beat a resurgent Ospreys (15 points) at Marcel-Michelin, while a home win for Saracens (13 points) might not be enough. And even if Northampton Saints are gone from the qualification race, expect them to come out firing at Allianz Park.
Pool Three: Impressive Leinster have already booked a home quarter-final, and a losing bonus point in Montpellier will see them ranked No 1 going into the knockout stage which statistically boosts their chances of a semi-final in Ireland. Montpellier (13 points) are still in the hunt for a best runner-up spot as are the Exeter Chiefs (14 points) who need a big win in Glasgow.
Pool Four: Another pool going right down to the wire. If Munster (16 points) get the better of Castres (12 points) at Thomond Park, then they will win the pool irrespective of what happens between Leicester and Racing 92 (15 points) at Welford Road as the Irish province have a superior points difference from the head-to-heads with Racing. A win for the TOP 14 side in Leicester, and they could well grab a quarter-final place.
Pool Five: A packed house at Parc y Scarlets is guaranteed on Saturday for the shoot-out between Scarlets (17 points) and RC Toulon (18 points). The winner takes all, and the loser will be left sweating on the possibility of a best runner-up place. Even if Bath (13 points) hit top form against Benetton in Treviso, a bonus point victory may still not be enough.
Qualification for the quarterfinals
The five pool winners and the three best-placed runners-up qualify for the quarterfinals, and will be decided as follows:
(a) The pool winner will be the club with the highest number of match points in each pool. The best-placed runners-up will be the three clubs with the highest number of match points out of the five clubs that finish second in their respective pools. For the quarterfinals, the pool winners will be ranked 1 to 5 and the best-placed runners-up ranked sixth, seventh and eighth by the number of match points earned.
(b) If two clubs in the same pool are equal on match points at the conclusion of the pool stage, then their ranking will be determined by the results of the two matches played between the relevant clubs as follows:
(i) the club with the greater number of match points from the two matches; or
(ii) if equal, the club with the best aggregate points difference from the two matches; or
(iii) if equal, the club that scored the most tries in the two matches.
(c) If ranking remains unresolved and/or if clubs have not played each other previously in the pool stage, qualification/ranking will be determined as follows:
(i) the best aggregate points difference from the pool stage; or
(ii) if equal, the number of tries scored in the pool stage; or
(iii) if equal, the club with the fewest number of players suspended under Disciplinary Rules in the pool stage; or
(iv) if unresolved, by drawing lots.
The clubs ranked one to four will have home advantage in the quarterfinals as follows:
Quarterfinal One: Club One v Club Eight
Quarterfinal Two: Club Four v Club Five
Quarterfinal Three: Club Three v Club Six
Quarterfinal Four: Club Two v Club Seven
The format for the semifinal matches in the Champions Cup recognises performances by clubs during the pool stage as well as the achievement of winning a quarterfinal match away from home.
Semifinal One: Winner Quarterfinal One v winner Quarterfinal Two
Semifinal Two: Winner Quarterfinal Three v winner Quarterfinal Four
The semifinals will be played at venues designated by EPCR, and the following clubs will have home country advantage in their respective matches:
(a) For Semifinal One
If the clubs ranked One and Four win their quarterfinals, the club ranked 1 will have home country advantage
If the clubs ranked 1 and 5 win their quarterfinals, the club ranked 5 will have home country advantage
If the clubs ranked 8 and 4 win their quarterfinals, the club ranked 8 will have home country advantage
If the clubs ranked 8 and 5 win their quarterfinals, the club ranked 5 will have home country advantage
(b) For Semifinal Two
If the clubs ranked three and two win their quarterfinals, the club ranked two will have home country advantage
If the clubs ranked third and seventh win their quarterfinals, the club ranked seven will have home country advantage
If the clubs ranked six and two win their quarterfinals, the club ranked six will have home country advantage
If the clubs ranked sixth and seventh win their quarterfinals, the club ranked six will have home country advantage
