Cardiff Blues coach Dai Young has hailed Sunday's Amlin Challenge Cup final as the biggest game in the region's history.
The Blues aim to lift their first piece of European silverware when they face Toulon at the Stade Velodrome in Marseille.
No Welsh side has ever claimed a continental crown but Young believes his men are capable of making history in the south of France.
"This is the biggest game since the region was born," said Young.
"We have shown we have the mettle and determination to go to tough places and get a result, and it won't get much more difficult than this weekend.
"Toulon are one of France's top teams who have very few weaknesses and few unrecognisable players.
"But we do think there are one or two areas we can expose. We have a lot of confidence and momentum at the moment and if we play the way we know we can, there is no reason we can't come away with the result we want. We're looking forward to the game."
Toulon will be directed at fly-half by England star Jonny Wilkinson who bids to cap his debut season across the Channel on a high.
And with Wilkinson's trusty boot a potentially deadly weapon, Young has warned his side to keep their cool and discipline against the French giants.
"Jonny Wilkinson runs their game and determines where teams play," added Young.
"Plus he has the quality and kicking accuracy from penalties that could punish us and keep the scoreboard ticking over if we show indiscipline.
"It will be a great occasion with 50,000 people in the ground, whether they are our or their fans. This big-game atmosphere should inspire our players."
