And Samoan centre Paul Williams admits winning the title would be 'special' after the upheaval at the club over the past 12 months.
The Paris giants have suffered from a lack of consistency in the Top 14 where they lie in ninth position after just 11 wins from 24 games. That lack of form saw head coach Michael Cheika sacked with assistants Christophe Laussecq and David Auradou taking over the running of the team, following a short stint by director of rugby Richard Pool-Jones.
But Europe has proved an ideal escape from domestic issues having stormed into the semi-finals of the Amlin Challenge Cup.
"We had some good performances in the pool stage and a great result in the quarter-final when we won away at Bath. It has been a trying season so far with results and changes at the top, but it would be fantastic to be able to come through all that by finishing with a trophy - it would be special," said Williams.
Stade over-ran Bath with four tries in their quarter-final clash at The Recreation Ground. And Williams believes they must show the same ambition if they are to clinch their first European title.
"We really looked to play more rugby in the quarter-final than we had before during the season. Perhaps we have been too conservative in the Top 14 but now the conditions are improving, it really suits our game," he added.
"Perpignan will be a great challenge, especially down at Stade Aime Giral, but everyone at the club is excited about another semi-final and the chance to win a major trophy."
