Whilst the performances were of the highest quality the Scarlets only managed three victories out of their six Pool games last season – a statistic Nigel Davies will be looking to put right.
The Scarlets contingent at the World Cup also impressed and big things will be expected at the Parc y Scarlets from the likes of George North and Rhys Priestland.
As well as the return of their International stars, captain Matthew Rees made his comeback form injury a fortnight ago and he will be raring to go up against the Castres front-row.
Castres will head to Wales in confident mood after a positive start to their TOP14 campaign.
Seven early wins in the competition has seen them rise to third and they will be hoping to carry that form into Europe.
You have to go back to 2002 for Castres last victory on the road in the Heineken Cup and that was also in Wales against Bridgend.
