Biarritz Olympique fell at Lansdowne Road in the quarter-finals and Irish centre Brian O'Driscoll declared, "It was fantastic playing a club game in front of that crowd and hopefully we'll have that again for the semi-final.
"Biarritz are a fantastic side but I don't really know much about Perpignan. We'll have to analyse what they have done to date in the tournament, but I'm just glad we've got through to the semis. I thought the dream was over in the last few minutes when the Biarritz centre broke through, but Girvan Dempsey came up with a great tackle and we were able to hang on."
Coach Matt Williams added: "Perpignan are a good hard side and they will present a different challenge to Biarritz. Manny Edmonds was very good for them against Llanelli and he's obviously a key player for them.
"I thought the crowd were magnificent at Lansdowne Road but it was hard for us to play the rugby they wanted to see. It really was a new experience for us as a team."
However, Biarritz coach Laurent Rodriguez believes Perpignan can succeed where his side failed.
"We knew how good they were but I thought it would be more difficult for us.
