Mark Mapletoft will join Harlequins after his role with the England Under-20s
England Under-20 head coach Mark Mapletoft has called on his young charges to carry the momentum of their impressive RBS 6 Nations campaign into this summer's IRB Junior World Championships.
Mapletoft named his 26-man squad to travel to Argentina in June, including just six survivors from the 2009 side that lost to New Zealand in the final.
But one notable absentee is star lock James Gaskell who is already ruled out with a foot injury while Ben Youngs and Courtney Lawes are also unavailable due to their call up to Martin Johnson's senior squad.
England Under-20s finished second in this year's Six Nations clash on points difference to champions Ireland despite seeing his squad ravaged by club commitments and injuries.
He said: "The way we finished the Six Nations with some of our attacking play makes it hard not to be enthused.
"The players not involved at the back end of the tournament - like Gloucester's Freddie Burns and Jonny May - have really bounced back fantastically well. You've got to have players in form.
"The forwards performed consistently well, so that part of selection was fairly straightforward.
"The backs were a little bit more complicated after guys came in from outside the squad and did well, and other guys have picked up some good game time with their clubs. Overall we've got a really good balance."
And Mapletoft insists his side can go one better and win the tournament this year, but admits that England face a test just to get out of a group that contains Ireland, France and hosts Argentina.
"The group will be fascinating with three very difficult matches. In the Six Nations we lost to Ireland, then beat France quite comfortably, and Argentina at home is supposed to be our 'easiest' game." he added.
"We'll have to be very strong. Whoever wins our group will be really battle-hardened going into the semi-finals."

England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
