The defeat to Racing was Clermont's only loss in their last 11 Heineken Cup pool matches and their record is a stark contrast to the Scarlets' recent Heineken Cup fortunes.
A 33-26 win over Harlequins in Round 1 was the Scarlets' only victory in the last nine games in the competition. They have also struggled against Clermont at home in recent years, failing to score any points against the French side in both 2008 and 2013.
"Clermont are one of the best teams, if not the best team, in Europe," said Scarlets hooker Ken Owens.
"They have a lot of strength in depth and you could see that by the size of their pack last weekend. They picked a big pack to do a job and I thought the boys did absolutely everything out there to stop them because they went through a lot of phases in attack.
"Perhaps on another day we could have come away with a losing bonus point, which not many sides manage over there. But we will learn a lot from the experience.
"Clermont felt the effects of the game, too. We have to recover well, turn up at Parc y Scarlets and put in a big performance.
"If we can get something out of the game, we are still very much in this group with Racing Metro to come, a side we have shown we can compete with, and then Harlequins at home in our final game, who we have already turned over.
"Perhaps we have taken a step back, but if we get it right on Saturday we are right in there."
