"We are excited by the challenge of going out there to play in front of 30,000+ fans and the players have been fantastic in the last few months," said Blues head coach Phil Davies.
Davies lost the services of outside half Rhys Patchell in his last game against the Dragons, ruled out for four months because of a knee injury, but have got Welsh loose head prop Gethin Jenkins back in the fold after fur frustrating weeks on the sidelines.
Jenkins could be a key figure in the Blues side, given that he was part of the Toulon squad that won the Heineken Cup last season. He will know better than anyone what makes Toulon tick at home and will need to galvanise the Blues pack for what is sure to be a trial of strength.
Toulon are in no mood to surrender their hard earned European title, although they have lost their last two games in the Top 14 - 14-9 in Paris against Racing Metro 92 and 22-21 last weekend at home against Grenoble.
The shock defeat to Grenoble meant Toulon dropped to fifth place in the Top 14, eight points behind the leaders ASM Clermont Auvergne. They won't want to make it three defeats in a row!
