The Pumas are the only team left in the tournament who did not receive a red or yellow card in the group stages.
That is no mean achievement, given the fact they played northern-hemisphere big guns Ireland and France in Pool D.
With flawless Scotland goalkicker Chris Paterson ready to pounce on any Pumas infringements, the south Americans know they cannot afford to incur the wrath of referee Joel Jutge at the Stade de France this weekend.
“Our discipline has always been our strong point,” said the Montpellier full-back or fly-half.
“We have to maintain it and I don’t think it will limit us. Maintaining discipline is fundamental because he (Paterson) is a great kicker.”
Paterson has not missed in 15 attempts at goal this World Cup and the Gloucester marksman certainly has a fan in Todeschini.
“He doesn’t have the same style as (England’s) Jonny Wilkinson, who kicks the ball very hard,” he added.
“He does something like a golf swing when he kicks and what I’ve really noticed is that he stands very parallel to the ball. When he kicks the ball, it’s like he wraps himself around it. With him, it’s more a question of quality than force.”
In Felipe Contepomi, Argentina have a top-quality kicker themselves and the Leinster star — who has 53 tournament points to his name already — has recovered from the flu in time to make this weekend and is set to partner twin Manuel in midfield.
The Bristol centre, the lesser-known of the Contepomi siblings, insists going into the game as favourites does not change things.
“We are facing a great opportunity, and we have a good team. We might not have this chance again.”
“Argentina and Scotland both made it here the same way, with no-one taking them into account at the start.
“They are going to try to play a strong game, starting with their line-out, and the keys will be the penalties and their kickers, who have been 100% effective.”
Many believe both teams will adopt negative tactics, and look to gain the upper hand in the battle of the boot in the search for good field position.
Former Australia winger David Campese even claimed it is a match between teams who are “the dullest of the dull”.
Argentina full-back Ignacio Corleto, who scored a sensational try in the opening-night 17-12 win over France, is of a different opinion.
“Contrary to what Campese said, I think it will be an historic event for world rugby,” said the Stade Francais flyer.
“People think that we are already in the semi-finals and that the match against Scotland is just a formality, but that’s not true. I think it will be tough.”
