This season, Leinster became only the fourth team to win the European Cup with a 100% record. Toulon in 1995-96 only had to play 4 games, Brive the following year just 7 games. The Pool stages weren't played on a home and away basis, and arguably, there were some poor teams that could be used as cannon fodder. Saracens went through the 2015-16 campaign with a 100% record, but they didn't have to face the level of competition that Leinster did this year. Leinster had to beat: Exeter (finished top of the Aviva Premiership table, and in the final) Montpellier (finished top of the Top 14 table, and in the semi-final) Glasgow (finished top of their Pro 14 Conference table) Saracens (back-to-back European champions, and in this year's Aviva Premiership final) Scarlets (joint top of their Pro 14 Conference table, and in the final) Racing 92 (finished 2nd of the Top 14 table, and in the semi-final) So my question is, is this the greatest European/Heineken Cup season that any team have ever had?
