The Warriors completed the Celtic League double over the Welshmen last season, and were the first visitors to smash the 50-point barrier against them.
Backs coach Sean said in today's Daily Record: "A big part of Llanelli's preparations will have been watching a video of our brilliant win down there.
"The memory of that will still be hurting and there is no doubt the experience will have them totally fired up to face us."
Sean and the team are desperate for a confidence boost just a week before the launch of their Heineken Cup drive.
He added: "With our trip to play Bourgoin looming, a positive result would inject a pile of self-belief at the right time whereas another defeat would give us a lot of hard thinking to do.
