London - Argentina will match strength with strength when they take on England at Twickenham on Saturday.
Coach Daniel Hourcade said on Thursday that he had opted for weight up front to counter English power.
"We have a very heavy pack of forwards because we know that's a strength of the English team," Hourcade said.
"The breakdown will be key and I think that whoever succeeds in dominating this area will have the initiative," he said.
"Playing against England is always an extra motivation and we know what class of opponent we will be facing. They are the second-best team in the world and the fact that we will be facing them for a third time this year gives a better idea of what might happen.
"Of course, all the games are different and this time they have made six changes from the team we played in June," Hourcade added.
