Munster flanker Peter O’Mahony admits that this weekend’s clash with Clermont is as big as they come on the club stage.
The Irish side currently sit top of Pool 1 with two wins from two so far against Sale and Saracens.
Clermont lost their opener at Allianz Park but bounced back with a bonus-point success against Sale to move to second in the pool, two points behind the Irish side.
They will face off twice over the next two weeks, with the first clash coming at Thomond Park, before a return fixture at the Marcel Michelin.
And after a hardfought win over Ulster in the Pro12 last weekend, O’Mahony expects another titanic battle against les Jaunards.
“It just doesn’t get any bigger, European-wise it’s nearly on a par with an international game,” said O’Mahony.
“It’s going be hugely intense, in fact it’s never anything but when we play each other, always fiery with both teams not wanting to give an inch.
“These are the days you want to be involved in, the biggest days in a club jersey. Fingers crossed it will be a great occasion.
“Clermont are a hugely competitive side, just look at their performances in the French Top 14 in the last few months.
“Even when they’re not going well, they’ve got guys in the team who can punish you from any part of the pitch and when they’re going forward they are a very tough side to stop.
“We’ll have to be on our game at the weekend.”
