But the 12,000 capacity at the Stade Aime Giral will feel like home compared to Lansdowne Road, where 45,000 Irishmen are expected to throw their weight behind Munster’s European title tilt.

Wasps have estimated that just 2,500 of their fans will make the trip to Dublin, giving the Irish provincial heavyweights – almost unbeatable at home anyway – a massive advantage.

But Dallaglio has vowed Wasps will not be intimidated and has even embraced the mammoth task before his Zurich Premiership kingpins.

The England skipper said: “This is the biggest match in the club’s history, there is no doubt about that. If we win we reach the final, so the potential of that occasion makes tomorrow enormous.

“We’re all very excited. We deserve to be in the semis because we’ve worked hard.

“We face Munster as English champions and we represent everything that is good in the English game.

“I’m a fan of Lansdowne Road and can’t help but become excited by the passion of Munster’s supporters.

“There are not many semi-finals in any sport played in front of a 48,000 crowd so this is going to be special.

“But we’re all ready for the challenge and know what we’re up against. It’s going to be a fantastic test playing in Dublin.”

Wasps are one of the few teams in Europe with the firepower to upset Munster on their own turf thanks to a physical pack which thrives on confrontation and some lethal runners behind the scrum.

Add to that the experience of international veterans like Rob Howley, Craig Dowd and Dallaglio himself, and Munster know they will be in for a titanic encounter – even on home soil.

One area of Wasps’ game which has come in for criticism, however, is their lineout and they will need to ensure this is firing tomorrow – especially as Munster will include Ireland locks Donncha O’Callaghan and Paul O’Connell in their ranks.

But Dallaglio said: “Every team’s lineout is a possible weakness. A good lineout can turn into a bad one very quickly.

“If your lineout is going well then it guarantees possession and allows you to start playing the game you want to. If it doesn’t work then you must find ways around it.

“We’ve been to Perpignan and Bath and had good days at line-out – we won both games with a bit to spare – so we are confident in our set-piece. It’s a key area of confrontation and we are ready.”

Wasps boast a raft of English internationals in their side while Munster are suitably endowed with Ireland’s Triple Crown heroes, setting up the prospect of a revenge mission after the World Cup winners were humbled by Eddie O’Sullivan’s men at Twickenham.

Dallaglio is quick to play down talk of a grudge match, though, and dismisses the international angle.

The 31-year-old added: “This game is about Wasps, not England. It’s a special day for Wasps supporters who have managed to get tickets.

“Ireland deserved to beat us in the Six Nations but now we’re looking forward to a different occasion.”
