MAXIMUM POINTS FOR POOL WINNERS: Leicester Tigers 20, Stade Francais 19. CURRENT TRIES: Leicester Tigers 15, Stade Francais 9
It's a straight shoot out between Leicester Tigers and Stade Francais. A win or a draw would be good enough to give the Tigers a ticket into the last eight as Pool winners. Stade must win on the road for the first time this season if they are to go through. Ulster can reach a maximum of 15 points to possibly finish in second place, but that won't be enough to gain one of the two best runners-up spots.
Ulster and The Dragons are out.
MAXIMUM POINTS FOR POOL WINNERS: Edinburgh Rugby 27, Toulouse 25. CURRENT TRIES: Edinburgh 14, Toulouse 14.
Edinburgh Rugby are the only unbeaten team in the tournament and have become the first Scottish team to reach the quarter-finals. But if they lose their unbeaten record in Toulouse they could slip from No 1 qualifiers to eighth. If Toulouse avenge their defeat in the Scottish capital in Round One, and take a bonus point, then they would have 25 points and be the top seed. A draw would take Edinburgh to 24 points and leave them in a possible shoot out on tries with Munster or Gloucester in Pool 5 for the top seeding.
Leeds Tykes and Neath-Swansea Ospreys are out.
MAXIMUM POINTS FOR POOL WINNERS: Leinster Lions 23, Biarritz Olympique 20. CURRENT TRIES: Biarritz Olympique 13, Leinster Lions 11.
Biarritz Olympique are back in the hunt for a quarter-final spot thanks to their first win on English soil at Sale Sharks. To overtake Leinster Lions and win the Pool outright they must either win with a bonus point, or win and not concede a bonus point. Leinster Lions only need to win or draw to guarantee a place in the last eight.
Sale Sharks and Cardiff Blues are out.
MAXIMUM POINTS FOR POOL WINNERS: Llanelli Scarlets 24, Northampton Saints 23. CURRENT TRIES: Llanelli Scarlets 15, Northampton Saints 13.
Llanelli Scarlets need a win or a draw at Franklin's Gardens to reach the quarter-finals. If they lose, even with a bonus point, then they are likely to struggle to qualify. As for the Saints, they must make home advantage pay with a victory over the Scarlets to make the last eight. If they lose, even with a bonus point, they will be out.
Agen and The Borders are out.
MAXIMUM POINTS FOR POOL WINNERS: Munster 24, Gloucester 24.
CURRENT TRIES: Munster 18, Gloucester 16.
The top two have home games in the last round with Munster hosting Bourgoin and Gloucester entertaining Benetton Treviso. Munster failed to score a try in Bourgoin, while Benetton Treviso have conceded a bonus point in every game this season. If both Munster and Gloucester achieve five points in their matches on Saturday they will be level on 24 points. If that is the case, Munster will go through because of their superior number of Match Points (5-4) from the two games played between the sides. However, 24 points will be good enough to guarantee the second placed team a runners-up spot. So, too, will 23 points if one or other of the teams fails to get a bonus point in victory. Just as with Edinburgh, both teams could finish as the top seeds, or seventh or eighth.
Bourgoin and Benetton Treviso are out.
MAXIMUM POINTS FOR POOL WINNERS: London Wasps 24, Perpignan 20, Celtic Warriors 20
CURRENT TRIES: London Wasps 18, Perpignan 13, Celtic Warriors 7.
The tightest Pool of the lot, with three teams still mathematically in the hunt for the title. In fact, all three could end up on 20 points on Sunday if the Warriors pick up a bonus point and win in Calvisano, Perpignan do the same at home against Wasps and Wasps get a bonus point in defeat. That would mean the decision on who comes top would first be made on the number of Match Points scored in the games between the three teams. After that it goes to the number of tries scored in the matches between the three teams (Wasps v Warriors 5-5 pts, 1-1 tries; Perpignan v Warriors 6-5 pts, 4-2 tries; Perpignan v Wasps 0-4 pts, 1-3 tries). One thing is certain. If London Wasps win or draw in Perpignan then they will win the Pool. If Perpignan win with a bonus point, and stop Wasps from taking a bonus point, then they will win the Pool even if the Warriors snap up five points in Italy because of their superior Match Points and Tries rating over the Welshmen. The Warriors will win the Pool if they take a bonus point in winning in Italy and Perpignan beat Wasps without either side getting a bonus point.
Calvisano are out.
