The Blues are unbeaten in this season’s tournament after reeling off six group wins, including doubles against Gloucester and Biarritz, before knocking out three-time European champions Toulouse.

They also added the EDF Energy Cup for good measure, scoring 50 points to inflict Twickenham humiliation on Gloucester just nine days ago.

And with six Blues players - Leigh Halfpenny, Tom Shanklin, Jamie Roberts, Gethin Jenkins, Martyn Williams and Andy Powell - having gained British & Irish Lions selection to tour South Africa this summer, confidence can rarely have been higher.

It is why the Blues are fancied in many quarters to become Wales’ first Heineken Cup winners, but Young acknowledges Leicester’s pedigree.

The Tigers won back-to-back Heineken Cups in 2001 and 2002 - seasons when they also landed the English domestic title.

Leicester will now arrive at the Millennium Stadium with that prestigious double again a possibility, having eased into this season’s Premiership play-offs as top seeds.

Young said: “They know how to win tight games.

“They are not going to be too worried if it is nip and tuck right at the end on Sunday. They have a lot of experience in their team, they are used to tight games.

“We played well against them at the start of the season (in the EDF Energy Cup) and came away with the win, but I think that is the only time we have beaten them in the last three or four attempts.

“Prior to that, what they have done really successfully against us is to have a big start - the first 20 or 25 minutes they came out and steamrollered us.

“We couldn’t handle their physicality in seasons gone by, but this year I think we stood up to it.

“The players know this is a massive game. If we play to our potential, I am confident we can win and we will win - if we are anything short, then we won’t.

“We know how good they (Leicester) are going to be. They are very streetwise - they have been around long enough.

“We want to play a fast, open game - they won’t want to allow us to play that type of game.

“We know what they are going to bring to the party. It is up to us to be more effective in what we do.”
