Joe Schmidt's Leinster - the 2009, 2011 and 2012 Heineken Cup champions - are targeting a fourth European title in five seasons and are contesting a third ERC final in successive seasons.
By contrast, Sergio Parisse and his team-mates suffered heartbreak in the 2011 tournament final in Cardiff when Harlequins edged them out 19-18. That followed the agony of two Heineken Cup final defeats, 34-30 to Leicester Tigers in 2001 and 18-12 after extra time to Toulouse in 2005.
Schmidt will take over the reins of the Irish national squad after the end of Leinster's season, which includes European and domestic finals on successive weekends, and would love to leave after guiding Leo Cullen's squad to a rare European double.
So far three clubs - all English - have done the Euro double, Northampton Saints joining Bath Rugby and London Wasps in winning both the Heineken Cup and the Amlin Challenge Cup.
Leinster are the sole survivors from the three Heineken Cup Pool runners-up who qualified for the knock-out stages of the Amlin Challenge Cup and have beaten two former tournament champions on their way to this Dublin showpiece contest.
London Wasps were beaten 48-28 at Adams Park with outside half Ian Madigan contributing 28 points, including one of their five tries, before 2012 champions Biarritz Olympique saw their hopes of defending the title and going a step closer to 2013 Heineken Cup qualification blown away.
Leinster turned on the style in a 44-16 RDS win that booked them a quick-fire return to their Dublin headquarters this Friday. There were five more tries - Amlin Man of the Match Jamie Heaslip - crossing twice to give them this shot at a fourth European title.
Standing in their way is a Stade Francais Paris squad desperate to make that European breakthrough.
They did Pool 5 doubles over London Welsh and I Cavalieri Prato, losing their away tie at Grenoble, to reach the knock-out stages as group winners.
They showed their intent with a commanding 36-20 win at Bath Rugby, Waisea Vuidarvuwalu and Hugo Bonneval each crossing twice, to earn a semi-final showdown at Perpignan.
They won that all-French tie 25-22, the boot of full back Jerome Porical contributing 20 of their points, and will be banking on him packing his kicking boots for the big one on Friday.
- Leinster Rugby are the only survivors from the three Heineken Cup pool runners-up who qualified for the knockout stage of the Amlin Challenge Cup.
- Stade Francais Paris will be playing in their second Amlin Challenge Cup final having lost to Harlequins (19-18) in the 2011 decider.
- Leinster will be appearing in a first Amlin Challenge Cup final and as former Heineken Cup champions will be bidding to become the fourth club (after Bath Rugby, London Wasps and Northampton Saints) to win both ERC tournaments.
- Stade Francais are one of six French clubs to have played in an Amlin Challenge Cup final along with ASM Clermont Auvergne (2004 finalists and 2007 winners), Pau (2005 finalists), Bourgoin (2009 finalists), Toulon (2010 finalists) and Biarritz Olympique (2012 winners).
- Leinster are the first Irish club to qualify for an Amlin Challenge Cup final. The only other non-English or non-French clubs which have appeared in a tournament final are the 2010 winners, Cardiff Blues, and Pontypridd who were defeated by Sale Sharks in 2002.
- Just four of 16 Amlin Challenge Cup finals since 1997 have not featured a French club.
- Despite regularly reaching finals, last season's all-French Amlin Challenge Cup final produced the first French winner of the trophy (Biarritz Olympique) since 2007 when ASM Clermont Auvergne beat Bath Rugby.
- The tournament is guaranteed a new winner this season, and there have been 12 different winners of the trophy since 1997.
