Rising Worcester star Harry Owens started the game in Bayonne
Young Warriors Harry Owens and Joel Diggins helped England Under-18s make an impressive start to the AER Championships with an emphatic 79-0 win over Portugal in Bayonne.
England, who have also included Worcester full-back Michael Penn in their championship squad, ran in 13 tries in a one-sided clash as they launched tin their bid to win a third consecutive title in style.
England will now play Ireland, who defeated Georgia 27-0, in the AER semi-finals at Tyrosse on Wednesday (April 4).
"We didn't really know what to expect so we were a little bit apprehensive," said Graham Whitmore, England's lead coach.
"Portugal thought they had a superior side to last year and their aim was to try to close the gap between us, but obviously that didn't happen.
"We played with real ambition and a willingness to attack from everywhere. I was pleased with the width and depth that we got into our game."
Huw Taylor, Jack Singleton and Andrew Kitchener helped England Under 20s win the World Rugby Under 20 Championship in Manchester last Saturday, as they swept aside Ireland 45-21 in the final at the AJ Bell Stadium.
