Chances: The Pumas have flattered to deceive for years, threatening to burst into the top echelon, but never quite managing that.
At times, their Rugby Championship form has promised more, and they can progress past pool play, if they strike the flaky French on the right day.
Equally comfortable on the wing or fullback, Moyano scored a memorable try against the All Blacks last year in Nelson. He is quick, evasive and a very intelligent player, and will be one to watch in Japan.
Bofelli will likely play in the midfield, but can slot in anywhere from No.11-15. He is an excitement machine, and part of a very skillful and dangerous Pumas backline.
The general is the key player for the Pumas. His open-field running is underrated, his kicking game is very good and he is lethal from anywhere inside his own half with the boot.
If Sanchez has a good tournament, the Pumas may match their semi-final effort of four years ago.
The Pumas skipper and their best player, Matera was arguably the best-on-show during Super Rugby, guiding the Jaguares to their first final.
He is destructive with ball in hand, strong on both sides of the breakdown and a brute of a defender - the complete rugby player.
While Lavanini can lose his head at times, he is a key part of Argentina's tight five. A very good lineout forward and a decent ball runner, if nothing else, watching Lavanini play will be entertaining.
