England Under-20s head coach Jon Callard insists his charges must be wary of a Wales side licking their wounds in their second match at the World Under-20 Championship on Saturday.
Callard has made four changes to the side that recorded an emphatic opening victory over Japan, including a start for Northampton Saints flyer Howard Packman, who made his Aviva Premiership Rugby debut against Leicester Tigers last month.
Reigning champions England are fresh from their 59-7 win over the Japanese on Tuesday while Wales were edged out 19-10 by France.
But a 21-15 loss to Wales at this year's Under-20s Six Nations still weighs heavily on Callard’s mind – and he has urged his side to be at the top of their game this time around.
“Wales played very well that day. We weren’t on our game and they forced a lot of errors,” said Callard.
"We learned a huge amount from that experience and have since progressed from strength to strength. Wales, however, will also have developed throughout the Six Nations so we know that tomorrow will be a tough fixture.
“A team always hurts after a defeat. In this competition every game matters because of the format, but for us it is about staying composed and keeping to our processes.
“Howard Packman and Kieran Treadwell add further experience to the side and were stalwarts of the Six Nations.
“We have a full squad to pick from, everyone is fit and raring to go, so we need to manage and rotate players in what is a long and demanding campaign.”
Wales include two changes from the side that lost to France, Pontypridd and Cardiff Blues pair Jarrod Evans and Liam Belcher coming into the starting line-up at fly-half and hooker respectively.
Wales’ coach co-ordinator Allan Lewis said: “We have strength in depth in these positions which gives us a chance to give these players a start in what is another huge game.
“It is obvious that we made too many fundamental errors against France which you can’t afford to do at this level. Even though we got back into the game, we weren’t able to build any continuity to our performance and that cost us.
“England have a powerful pack, we know their strengths and weaknesses and although they are champions at this level, teams change every year at this age and we beat them in the Six Nations so we know we can win if we perform as we did in Colwyn Bay.
“We have trained well, but our priority is to play as we’ve trained. If we do that, and are accurate and clinical, as we know we can be from some of our Six Nations performances, then the result will take care of itself.”
