Basic Heineken Cup rules

1(a) Pool Matches

Four points for a win, two points for a draw (match points). A bonus point will be earned by a team scoring four or more tries and by a team losing by seven or less points. The six pool winners and two best placed runners-up will qualify for the quarter-finals and will be decided by the following criteria:
(i) the pool winner will be the club with the highest number of match points earned in each pool. The runners-up will be the two second placed clubs from all six pools with the next highest number of points. For the quarter-final round, the pool winners will be ranked 1 - 6 in terms of the number of points earned. The runners-up will be ranked 7 and 8.
The knock-out stages of the Amlin Challenge Cup tournament will include three clubs who will qualify from the Heineken Cup.
The introduction of three clubs who have finished as the third, fourth and fifth pool runners-up in that season's Heineken Cup into the quarter-finals along with the five Amlin Challenge Cup pool winners will enhance both the quality and profile of the Amlin Challenge Cup knock-out matches.
The top four Amlin Challenge Cup pool winners will have home advantage in the quarter-finals with the highest-ranked pool winner playing the fifth-ranked pool winner, and the other three pool winners playing Heineken Cup clubs.

Quarter-finals qualification if clubs are equal:

Clubs in the same pool

(ii) if clubs are equal on points and the clubs are in the same pool, then qualification/ranking will be based on the two matches played between the clubs concerned:
(a) the club which has earned the most number of match points from the two matches (four points for a win, two points for a draw and bonus points).
(b) the club which has scored the most tries in the two matches.
(c) the club with the best aggregate points difference from the two matches.

Clubs from different pools (if still unresolved)

(iii) if the clubs have not played each other previously in the pool stage, qualification/ranking will be based on:
(a) the number of tries scored in all pool matches.
(b) aggregate points difference from all pool matches.
(c) the club with the fewest number of players sent off and/or suspended in all pool matches.
(d) toss of a coin.

So in lead up to final pool round we have this;
Pool 1

1

Saracens

18pts

2

Munster

Rugby

15pts

Sarries play Edinburgh which should be an automatic win with maybe a bonus point.

Munster play Racing at home which should also be a home win as Racing have nothing to gain.
