The race for quarter-final qualification is entering the home straight with the majority of the coveted eight places set to go all the way to the completion of Round 6 matches on the weekend of 19 / 20 / 21 January...
POOL 1
Pool 1 leaders London Wasps face back-to-back French tests but a home win for the 2004 Heineken Cup champions over second placed Perpignan in Round 5 would go a long way to booking a quarter-final place. Perpignan need to win at Wasps and home to Benetton Treviso in Round 6 to stay in the mix for qualification as Pool winners.
Maximum points attainable:
London Wasps - 25 points
Perpignan - 23 points
Castres Olympique - 20 points
Benetton Treviso - 10 points
POOL 2
It might still go down to the wire in Pool 2 when Leinster travel to Kingsholm to face Gloucester Rugby in Round 6 but the Irish province, who already have a healthy four-point cushion at the top, could put a foot in the quarter-final door by beating Edinburgh at Donnybrook in Round 5 while Gloucester must win at Agen. Two wins for Agen would keep them in contention.
Maximum points attainable:
Leinster - 25 points
Gloucester Rugby - 21 points
Agen - 19 points
Edinburgh - 15 points
POOL 3
The losing bonus point Stade Français Paris picked up at Sale Sharks in Round 4 could end up being priceless as it gives them the edge in a Pool that might still need a slide rule. The Ospreys must beat both Stade Français Paris at home and Sale Sharks away while the Paris club finish with a home match against Rugby Calvisano.
Maximum points attainable:
Stade Français Paris - 25 points
Ospreys - 24 points
Sale Sharks - 20 points
Rugby Calvisano - 10 points
POOL 4
Defending champions Munster - who have now won a record 12 successive Heineken Cup matches - travel to the new tournament venue of Geneva aware it could still come down to Leicester Tigers' visit to Thomond Park in Round 6 to decide the group winner.
Maximum points attainable:
Munster - 28 points
Leicester Tigers - 24 points
Cardiff Blues - 15 points
Bourgoin - 10 points
POOL 5
Llanelli Scarlets are in the driving seat and a win over Ulster Rugby at Ravenhill in Round 5 would put them in the last eight with a match to spare. Ulster must win that match and then win at Toulouse to stay in the hunt.
Maximum points attainable:
Llanelli Scarlets - 28 points
Ulster Rugby - 20 points
Toulouse - 18 points
London Irish - 16 points
POOL 6
Biarritz Olympique could become the first team to qualify with a maximum 30 points since the introduction of bonus points in season 2003 / 2004. They play their 50th tournament match when they meet Overmach Rugby Parma at Parc des Sports Aguilera in Round 5 and could celebrate by guaranteeing themselves both a quarter-final place and a home match for good measure. Northampton Saints are the best placed runners-up so far with 15 points in the hunt for the two final knock-out places to be earned along with the six Pool winners.
Maximum points attainable:
Biarritz Olympique - 30 points
Northampton Saints - 25 points
Border Reivers - 15 points
Overmach Rugby Parma - 10 points
