Holders Wasps are braced for another ferocious European test on Saturday, with rugby director Ian McGeechan admitting: "Every game feels like a cup final."
A week after edging out Munster in a pulsating Heineken Cup Pool Five encounter, Wasps head to Stradey Park for an appointment with Llanelli Scarlets.
The game comes just 48 hours after Llanelli's famous old ground staged an emotional farewell to Ray Gravell, one of their greatest players, who died suddenly while on holiday in Spain.
McGeechan said: "It has been a very emotional week for the people of west Wales.
"And in what is always such a good rugby corner of the world there, we know the game will be played in a very intense atmosphere.
"Pool Five is so competitive that every game feels like a cup final, and that is how we will be approaching the game against Llanelli."
Wasps are unchanged following the 24-23 success against Munster, but a notable bench alteration sees Josh Lewsey included after recovering from the hamstring injury which ruled him out of last month's World Cup final between England and South Africa in Paris.
The Scarlets welcome back fit-again skipper Simon Easterby and wing Mark Jones - both players missed last Sunday's defeat against Clermont Auvergne - as they target a third home Heineken Cup victory over Wasps following successes in 2000 and 2005.
Scarlets rugby director Phil Davies said: "I had a bit of a look at Wasps' game against Munster, but we already knew enough about them.
"We know they are a quality side - they would not be champions of Europe if they weren't."
