Dimitri Yachvili and Peter Stringer go head-to-head again when Biarritz Olympique and Munster meet at Estadio Anoeta in San Sebastian just three weeks after facing each other in their national causes.
Yachvili was the 26-19 winner at Lansdowne Road in the Six Nations, kicking eight points for France, but accepts that Munster's wealth of experience in the knock-out stages of the Heineken Cup could be a powerful and major influence.
"We are expecting a big game and a huge challenge from Munster," said the Biarritz scrum half. "The Munster team boasts a great deal of talent with so many players in the Irish national squad.
"What is more, having been involved in six quarter-finals in the last six seasons they have certainly shown that they have the quality of a top European team.
"And the strengths of the Munster team are that of the Irish team, with a very strong pack and set pieces which allows them to make good progress up the pitch and, despite the loss of Ronan O'Gara with a knee injury, they still have many talented players behind their strong pack.
"However, we are going into this match with confidence in our team which has a very good start to 2005 after our defeat of Toulouse.
"It's a source of great pride to host a team like Munster in a stadium like Anoeta. It's an unfamiliar ground to us and a big first to play there, but we also know the fierce pride of our supporters and that they will turn out in droves to support us. It's up to us to put everything into this match and give them a fantastic moment."
