Toulouse - 53 Llanelli - 36: Llanelli were put out of their European misery by a clinical Toulouse side at Stade Ernest Wallon last night.
A try double from hard-working lock Chris Wyatt kept the visitors in the match at half-time but there was no stopping the French heavyweights as they wrapped up the match.
The home side were rocked by a Wyatt try under the posts in the 10th minute. A ridiculous pass from fullback Clement Poitrenaud went over the head of centre Yannick Jauzion and into the arms of secondrow Wyatt to gallop over the line untouched.
But the try simply made Toulouse angry. Vincent Clerc went over in the corner after skilful handling from scrumhalf Jean-Baptiste Elissalde and poor defence from the Scarlets, and Jauzion crashed over near the posts following good work from outhalf Frederic Michalak.
Gareth Bowen narrowed the margin with a penalty goal. But Gareth Thomas increased the hosts' lead as he crashed through the attempted tackles of Garan Evans, Dwayne Peel, Dafydd Jones and Tal Selley.
Toulouse's dominance was illustrated with a penalty try which gave them a bonus point and a guaranteed home quarter-final, and flanker Jean Bouilhou made things more one-sided with a pushover try moments later.
The Scarlets refused to drop their heads, though, and Wyatt reached over from a close-range scrum to narrow the score to 33-17 at half-time.
Michalak opened the second half with a superb drop goal, before a stunning break from hooker William Servat set up Poitrenaud for his side's sixth try.
Replacement backrow Andy Powell gave the Scarlets much-needed momentum up front, and hard work paid off when prop John Davies forced his way over the try line after a good build-up from captain Simon Easterby.
Powell scored a try to give his side a well-deserved and completely useless bonus point.
Poitrenaud and replacement scrumhalf Jean-Frederic Dubois restored the home side's authority with late tries, and the Scarlets were left with a consolation touchdown to Selley.
