So much hinges on their opening match against England. Four years ago they gatecrashed France's first-night party in Paris and went on to finish third in the tournament. They still have a scrum to be reckoned with but the loss of the injured Juan Martín Hernández will diminish their attacking potential. In a tight contest, even so, with the outstanding Juan Martín Fernandez Lobbe, Juan Leguizamon and Patricio Albacete all fit and firing, the Pumas will be tough hombres to overcome. They should not be underestimated.
Key player: Felipe Contepomi. The captain and fly-half did not have best game against Wales last month but will be at the heart of the Pumas' tactical plans. Will be expected to slot his goals.
Commentator's kit: Contepomi, Argentina's captain and fly-half, is a qualified doctor. His brother Bebe, more excitingly, is a leading Argentinian rock'n'roll journalist and radio presenter.
