Tokyo - Argentina have turned to mercurial Stade Francais flyhalf Nicolas Sanchez to pull the strings for Los Pumas' opening Rugby World Cup Pool C match against France on Saturday.

Kick-off is at 09:15 SA time.

Sanchez has a ream of French experience, having also played for Stade's Top 14 rivals Bordeaux-Begles and Toulon over four seasons before linking up briefly with the Jaguares in Super Rugby.

Argentina will be skippered by marauding flank Pablo Matera in a strong-looking pack that sees Saracens' Juan Figallo starting at tighthead prop.

The third player in Argentina's 31-man squad attached to a club outside the South American country is also included, as coach Mario Ledesma named goal-kicking Castres playmaker Benjamin Urdapilleta on the bench.

The rest of the match-day team play for the Jaguares, who made it to the Super Rugby final in July, going down 19-3 to the Crusaders.

The team that takes its chances will prevail in what is expected to be a tight game with "two good defences," said head coach Mario Ledesma.

"France has changed the way they defend. They defend very high up and leave little space," he said.

"I think the key will be unlocking this defence and the kicking game will play an important part," added Ledesma, who has a close link to France, having been based there as a player and a coach.

"The mental aspect will be important. To be able to do what you want to do."

Saturday's clash in Tokyo will go a long way to determining the fate of Pool C, dubbed the "group of death" as it also includes in-form England.

Matera said the match was quite simply "the most important game of our lives."
