Leinster play-anywhere three-quarter Fergus McFadden believes "there has been a bitter taste" from losing the last two PRO12 League finals.
They have lost the last three. The first was to the Ospreys in 2010 where Leinster were soundly beaten. The second saw Munster prevail and last year the Ospreys won again.
"We are really targeting that (the PRO12)," he said, as the Amlin Challenge Cup final looms large on Friday night.
It is understandable that the Leinster players should talk about doing something unprecedented this season. They have won the last two Heineken Cups, but been beaten in the last two league finals.
"The first year when Munster beat us they just played better on the day," added McFadden. "The Ospreys last year, we were kicking ourselves after that to be honest. Don't get me wrong, the Ospreys are a good team, but we shouldn't have lost that game.
"We let them into the game twice or three times, and obviously Shane Williams scoring those two tries on his last appearance.
"We're still bitter about that genuinely, but that's for next week. This week it's the Amlin and we really want to win that first."
Stade Francais have never really delivered on their European potential, losing two Heineken Cup finals in 2001 and 2005 and one Challenge Cup final in 2011.
"Stade are really fired up for this, you know. You saw the way they were jumping around after beating Perpignan and the nature of the way they beat them.
"It was a pretty tight game and we are not taking them lightly and it is going to be hopefully a great day in the RDS," said McFadden.
Glasgow Warriors stretched Leinster to their breaking point in the PRO12 League semi-final last Saturday. It took a lot of energy out of them, and personnel too, definitely Gordon D'Arcy, maybe Brian O'Driscoll.
"I certainly don't think we are going to run out of steam. I think, if anything, this business end of the season, when you are in with a shout of two trophies, you couldn't be more up for it."
ULSTER centre, Luke Marshall, has signed a new three-year deal with the club that will see him remain at Ravenhill until at least the summer of 2016.
The 22-year-old Irish international said: "I am delighted to staying with Ulster. I have really enjoyed my rugby this season and I am looking forward to August already and to getting back out onto the pitch."
