Eddie Jones expects to take the struggle as England prepare to find serious in their bid to maintain another Webb Ellis trophy.
England have created a start to the championship with wins Tonga and the USA to top the poolbut face their initial tier-one resistance in the Pumas.
They come up against an Argentina side in need of a win to maintain their World Cup dreams alive having lost over the opening weekend to France. Coached by former hooker Mario Ledesma, Argentina have tried to create their once formidable scrum .
Ledesma has made repairing up issues front a World Cup priority ever since Argentina conceded three attempts from scrums in a 28-17 loss to Ireland in Dublin last November, but Jones is eager to take the Pumas on at their very own game.
It will be a huge evaluation on Saturday and they have not scrummed against us yet, Jones said in Tokyo on Thursday.
We think our scrum may be true weapon for us hold onto your chairs.
Englands scrum will be helped by the return from injury of prop Mako Vunipola, albeit on the seat. Loosehead Vunipola had surgery after tearing his hamstring in the bone and has played just 17 minutes of rugby since, using a brief cameo from Ireland where he awakened the scar tissue.
England will be eager to avoid any aggravation of the accident on Saturday, so Joe Marler retains the No 1 top having Vunipola going to emerge on in the second half.
Apart from that, England will look down to bed key combinations for your campaign before their final pool game against France and the knockout stages to come.
While the back-row and the power of Makos brother Billy Vunipola combine the mobility of Tom Curry and flankers Sam Underhill George Kruis and maro Itoje lineup for the very first time this tournament together in the next row.
Jones admitted selection had been among his choices.
We have four quality back-rowers that are there, all competing for a place, said the Australian. Curry and Underhill, particularly given the requirements, we think will be useful in terms of the contest in the breakdown.
[Lewis] Ludlam has just impressed us at the World Cup with his power, his excitement but Mark Wilson is unfortunate to not have chosen.
