Argentina fly-half Felipe Contepomi has said that their match against Wales in August will be crucial to their Rugby World Cup preparations.
The Pumas take on Wales at the Millennium Stadium on August 20 before a clash with recent Aviva Premiership arrivals Worcester Warriors.
"It is always a pleasure to play against Wales. They are one of the proudest rugby nations, I think it will be a party atmosphere and both teams will take a lot out of it in terms of preparation for the World Cup", the 68-cap Buenos Aires native said.
"It's the key game for us in our preparation for the first game against England and it will be crucial for us."
Argentina kick off their Rugby World Cup campaign against Group B opponents England in Dunedin on September 10.
The teams share their pool with Scotland, Georgia and Romania.
