the Scarlets haven't achieved much in Europe since 2007 though, the Ospreys have reached the quarter finals three times since then, and still have cursed luck with the draw every year
Ospreys pool history:
2005/06: Leicester, Stade Français, Clermont
Leicester were the Premiership runners up that year, Stade had been Top 14 and Heineken Cup runners up the previous season
2006/07: Stade Français, Sale, Viadana
Stade won the Top 14 that year, Sale were the reigning Premiership champions the previous season
2007/08: Gloucester, Bourgoin, Ulster
Gloucester topped the Premiership table that season, and the season before, the other two weren't that strong though, probably the easiest one the Ospreys have had
2008/09: Leicester, Perpignan, Treviso
The Premiership and Top 14 champions that season
2009/10: Leicester, Clermont, Viadana
The Premiership and Top 14 champions that season
2010/11: Toulon, Munster, London Irish
One of the richest teams, the team who always reaches the knockout stages, and a tricky team to face as a fourth seed in a group
2011/12: Saracens, Biarritz, Treviso
English champions the previous season, and the Amlin Challenge Cup winners
2012/13: Toulouse, Leicester, Treviso
The Top 14 champions and the Premiership runners up
that is about 6 "pool of deaths" in 8 seasons and compare to ...
Biarritz pool history:
2005/06: Saracens, Ulster, Treviso
the team that finished 10th in the Premiership that season, and Ulster who although winning the Magners League weren't up to European level
2006/07: Northampton, Borders, Parma
the 12th placed team in the Premiership, and Borders and Parma ... yet they still hilariously mucked up the quarter final
2007/08: Saracens, Glasgow, Viadana
the 8th place team in the Premiership, and Glasgow and Viadana ... and still didn't qualify
2008/09: Cardiff Blues, Gloucester, Calvisano
Quite a decent group, with Cardiff nearing the peak of Dai Young's spell in charge, and Gloucester still decent
2009/10: Gloucester, Dragons, Glasgow
just as Gloucester declined after their good team in the mid 2000's, and two teams who have never gotten anywhere in the Heineken Cup, meant they could get a home quarter final thanks to the easiness
2010/11: Ulster, Bath, Aironi
no teams who reached the league playoffs that season
2011/12: Saracens, Ospreys, Treviso
probably the hardest Biarritz have had, which says a lot
2012/13: Harlequins, Connacht, Zebre
the two worst teams in the tournament
