Form: A superb Rugby Championship win over South Africa - the first in their history over the Springboks - offered a glimpse of what Argentina are capable of when they hit top gear. A tryless defeat against the same opponents seven days later, however, suggests the Pumas still lack the penetration and consistency to challenge.
Captain: Agustin Creevy, a tenacious hooker, is also renowned for his handling skills and brings much-needed experience to the Argentina ranks. The 30-year-old played at the 2011 World Cup and has represented Biarritz, Clermont and Worcester at club level.
Star player: Juan Martin Hernandez. Argentina's strength traditionally lies in the pack but Hernandez's creativity injects sparkle into the back line. The 33-year-old has 53 Test matches to his name and his reliable boot is a valuable weapon.
World Cup history: Argentina's steady progress on the international stage gained lift off in 2007 when they beat Ireland and France, twice, to finish third. Before then, the Pumas had only escaped the Pools once in five attempts. They did so again four years ago, before losing to eventual champions New Zealand in the quarter-finals.
