Shaun Edwards's offers a tactical breakdown of England v Argentina in the Guardian.
"Forget the tactical nuances, Argentina are in town and the big men love nothing better than throwing their weight around – actually weight and a fair bit of technical know-how when it comes to scrum time.
While England have struggled to find a front row the three Argentinians, Rodrigo Roncero, Mario Ledesma and Martín Scelzo, have been together for some time. They know their business and on days like today when rain is forecast can be match winners. In short, an awful lot is going to depend on England's tight-head and anchor, Duncan Bell. If he goes backwards, the link between backs and forwards at the scrum breaks down."
