Former Argentina rugby player Marcelo Bosch believes the Argentinians have their best chance in four seasons to avoid finishing last in the Rugby Championship which starts on Sunday.
He says there was little doubt the success of the Jaguares in reaching the final of the Super Rugby competition would be reflected in their Test side.
Bosch says the core of the team at the Rugby World Cup will be from the Jaguares.
Argentina takes on New Zealand at 6.05am Sunday while the Wallabies will take on the Springboks at 3.05am Sunday.
