But Jones insists that for England to prevail, they must win the forward battle.
“Argentina base their game on the scrum. It’s a test of manlihood so you have to take them on up-front – scrum, maul, ruck attack, ruck defence. That’s where it will be won,” Jones said.
“Everyone trained really well – they’re looking fit, fast, brutal and ready to go.”
Defeat would almost certainly send Argentina home at the end of the pool stage and the Pumas camp have invoked an air of desperation in hope of upstaging a team that sits seven places higher in the global rankings.
Jones, however, does not see their precarious position as an opportunity to be exploited.
“It is not a matter of us taking advantage, it’s a matter of us preparing well for the game,” he said.
“We have prepared well for the game and physically we are in the best position we have ever been in.
“We can’t be seduced by Argentina’s state. We know they play with a lot of pride and a lot of passion and that will be multiplied by the fact they are in a game that’s very important to them.”
Meanwhile, although England have rebuilt following last year’s six-match losing sequence but doubts over their big game temperament persist due to their tendency to throw away leads – a frailty that cost them the recent Six Nations.
Every team faced now will be tier one opponents so slip-ups cannot be afforded and Jones insists every effort has been taken to enable his players to deal with pivotal moments in games.
“We have worked hard on it, on creating training situations to equip the players for it,” he said, adding: “It’s a bit like a tea bag isn’t it? You don’t know good it is until you put it in hot water.”
After a hit-and-miss group stage for the Wallabies, and a momentum building prelude to the knockout stages for the English, it is do-or-die as the Rugby World Cup quarter-finals get underway with a bumper clash between two of the oldest enemies in global sport.
