Munster captain Peter O'Mahony said his team will have to produce their best performance of the season "by a distance" as they take on "the best team in Europe".
Munster head to the RDS at the weekend to play the newly crowned European champions in the Pro14 semi-final.
They've already suffered two defeats against Leinster in this season's Pro14, losing 23-17 in the Aviva Stadium in October and then coming out the wrong side of an eight-try encounter in Thomond Park on St Stephen's Day.
More promisingly, Leinster's experience of major domestic encounters the week after European Cup victories has not been positive.
They were defeated by Munster in the final of the 2010-11 Magners League seven days after beating Northampton in the Heineken Cup final. And then, eight days after demolishing Ulster in the Heineken Cup final the following year, they were turned over by Ospreys in the Pro12 final.
Speaking to RTÉ Sport, O'Mahony said it was great to see another Irish province win Europe.
"They've beaten the best there is Europe. Exeter, Glasgow, Racing and Saracens, they're all teams that are near the top of their domestic championships so they're deservedly champions. It was great that it was another Irish province win it."
Munster have struggled badly in head-to-head battles with Leinster in recent seasons. Leinster failed to win a single match in Thomond Park between 1995 and 2010, but have won five times in Limerick's sacred turf since then. Munster's 34-23 win in the Aviva Stadium in October 2014 is their sole win over Leinster in Dublin this decade.
O'Mahony puts the run down the quality Leinster have at the moment.
"The standard that they have at the moment is very, very high. They've beaten everyone that's worth talking about. That's why they have the trophy. They've 18 or 19 guys who were involved in our Grand Slam win. That stands to a club team. It's fairly remarkable."
He acknowledged that Munster need to produce something that hasn't been seen from them this season.
"People go on about our strength in depth but I don't think we'd have been in as many semi-finals as we have been if we didn't have a certain amount of it.
"It's going to have to be something very special from us with the form they're (Leinster) in, not just the last few weeks but the whole year. We're going to have to do something different and have the best game of our season by some distance."
