But s his team prepares to go into battle against Racing Metro, Harlequins and Scarlets in Pool 4 next month Rougerie says that what happened in Dublin is now old news.
"We were bitterly disappointed after losing to Toulon in the final last season, but that is now behind us. We needed to turn the page on that season and move on," admitted Rougerie.
"We always work hard before the Heineken Cup to ensure we are ready for the challenge because it is an important tournament for all of us at the club. The concentration levels and atmosphere within the squad in the weeks building up to the Heineken Cup are both greater than in other weeks.
"I want to win the Heineken Cup before I retire, but then so do so many other players at great clubs like Racing, Toulouse and Toulon. It is going to be hard, but I just hope the tournament can continue. I hope they can find a solution that allows us to carry on playing in the competition because it is very good."
Even though their remarkable home form has been as good as ever this season, Clermont have slipped up on the road and were beaten 43-3 last weekend in Montpellier in a re-run of last season's Heineken Cup quarter-final.
"I don't know what happened last weekend. It looked as though the team simply didn't want to play in Montpellier. It is difficult to find an explanation for what happened, but I will check with the layers when I get back into action next weekend," said Rougerie.
"We are in a difficult Pool in the Heineken Cup and we know the scoring potential and pace that there is in the Harlequins side. Then we have Racing Metro, who have recruited so many great players, including the former Leinster outside half Jonny Sexton who has won the Heineken Cup three times.
"I don't know how good the Scarlets are this season, but I know it is going to be very hard to qualify for the quarter-finals this season."
