ARGENTINA

Lowdown
The surprise package in France four years ago, Argentina are unlikely to be underestimated this time around. Santiago Phelan has crafted a side that is more than just a powerful scrummaging unit, with full-back Martin Rodriguez one of several talented youngsters. Phelan believes he will have his strongest possible team available for Saturday’s crunch opener against England, although that is of course without injured fly-half Juan Martin Hernandez, one of the stars of their run to the semi-finals in 2007.
