England's backs provided all five tries as Argentina crashed to a 45-16 Churchill Cup final defeat but coach Joe Lydon felt the clash was won up front.
Pre-match talk had centred around the strength of the Pumas' juggernaut pack and the damage it would inflict upon England, but it was Pat Sanderson and his troops who reigned at the Commonwealth Stadium in Edmonton.
Lydon said: "If you look at the scoreboard afterwards it sums up how well our forwards played. They were immense. The scrum was fantastic. We took Argentina on at their own game. Our scrum set the platform for us to win.
"They set out to out-muscle us up front but it didn't happen. I was pleased with the way the backs played but the opportunities were created by the forwards, who were magnificent."
Tom Voyce ran-in a brace while James Simpson-Daniel, Paul Sackey and Andy Gomarsall also crossed as the searing pace of England's threequarters proved decisive.
Lydon added: "The backs scored the tries - Simpson-Daniel, Sackey and Voyce. Guys like that can change positions and do it well. They don't balk at the challenge of changing positions, in fact they relish it.
"From one to 22, everyone performed. When the substitutes came on they raised the game. Mike Shelley was a prime example. He came on and the tempo went up at the next scrum as we got the shove on.
"I was pleased with the performance. I thought we played some good 15-man rugby. We set out to eradicate the mistakes from last week. We still made some errors but that's being critical of a very, very good team display."
Argentina skipper Matias Albina felt England's superior fitness levels were the decisive factor behind the outcome but was pleased by his side's defence - even though it leaked five tries.
"It was a very hard match. England played very well. We tired in the last 15 minutes and that made a big difference. They played very well in the forwards and then made a difference in the backs," said the scrum-half.
"It's difficult to combat their speed. I think we managed it for 60 minutes but then they added more tries. Our defence was good and we made some good tackles. It was better than last week against the USA."
Italy Under-20s held off a late Samoa blitz to retain their place in the World Rugby U20 Championship on Saturday and head coach Alessandro Troncon believes the experience will have served as a valuable lesson for his young troops.
