Rob Penney admits Munster face a massive challenge against Clermont Auvergne but he has urged them to thrive on their underdog tag.
The two-time Heineken Cup champions face the French giants in this season's semi-finals in Montpellier on Saturday.
Penney is well aware of the challenge facing his side against the bookmaker's favourites to succeed Leinster as kings of Europe.
But he insists his Red Army will stand up and fight for the full 80 minutes.
He said: "There's no doubt Clermont are roaring hot favourites and we're underdogs. You can either thrive under that tag or wilt away.
"The best teams should be in the Heineken Cup at this stage and Clermont are certainly in that bracket.
"They've got real depth. We were going through their substitutes and you would be just wrapped to have them. They have an All Black 9, 10, 12 and 13 on the bench and Sitiveni (Sivivatu) starts on the wing.
"But we still have a lot of expectation from the Munster public and supporters, it's a double-edged sword.
"I don't want to say we believe we will beat them but we are going to go over there and give it a good crack. A game of rugby is such a dynamic one that on any given day an underdog can pull it off.
"It's 15 versus 15, we have a great referee in Nigel Owens and we just have to make sure we prepare well and perform."
Munster warmed up for their European day of destiny with an agonising last-gasp 30-24 defeat to Newport Gwent Dragons.
The Limerick-based province have now lost their last two matches but Penney, who rested the vast majority of his first team stars, insists it will not knock their confidence.
"We were disappointed with the result in the end. It was one of those games where we lost it in the first-half. We came back well but couldn't quite complete.
"It won't affect confidence at all. We have managed to get into a semi-final and now have to focus on a massive game against Clermont."
As part of the build-up to next month's Cardiff 2014 Heineken Cup and Amlin Challenge Cup finals weekend, ERC has joined forces with the WRU, Cardiff Blues and adidas to develop an annual grassroots community rugby programme targeting young players.
