The default allocation of teams was as follows: • England: 6 teams, based on performance in the
Aviva Premiership and
Anglo–Welsh Cup • France: 6 teams, based on regular-season finish in the
Top 14 • Ireland: 3 teams, based on regular-season finish in
Pro12 • Wales: 3 teams, based on regular-season finish in
Pro12 • Italy and Scotland: 2 teams each, based on participation in Pro12 (as there are only 2 from each nation) The remaining two places were filled by the winners of the previous year's
Heineken Cup and
Amlin Challenge Cup. If the cup winners were already qualified through their domestic league, an additional team from their country would claim a Heineken Cup place (assuming another team was available). Accordingly, since Heineken Cup winners Toulon were already qualified through the Top 14, the extra French berth went to
Perpignan. Also, since Amlin Cup winners Leinster were already qualified through the Pro12, the extra Irish berth went to
Connacht. Teams are listed in the order they were presented to Heineken Cup organiser
European Rugby Cup by their respective leagues. ==Seeding==
