Stade Français Paris - last season's finalists - Brive, Toulon and 2003 champions Wasps were the four Pool winners to clinch home advantage while Exeter Chiefs marked only their second season in European club rugby with a place in the last eight and a trip to Paris.
The growth in both status and popularity of the tournament is reflected by the 273,167 spectators who attended the Pool matches in this season's tournament. That figure represents a significant 17% increase on the 2010/11 total of 233,598.
