The Red Rose take on Scotland later this evening, a physical encounter Sinckler has experience of after featuring in the 59-3 victory in Glasgow last year.

And with a new-look contingent, the 19-year-old believes the more intricate focus on style rather than substance will help nullify the threat posed by Scotland.

"I started the game last year up in Glasgow and I think only a few Scotland guys who were involved last year are playing in the team for Friday,” said Sinckler. “So it's almost a whole new squad like it is here – bar a few players.

“We're expecting a really tough match. It's international rugby, all the games are really tough and it's about small margins. We'll focus on ourselves and see what happens.

"What we've tried to focus on this year is less outcome goals, and focus on what leads to that outcome. So we'll focus on certain things throughout the week whether that be our set-piece, something to do with our attacking game or defensive game.

“We know if we hit those three or four things in each part: attack, defence, set-piece then we'll be fine and that outcome goal will be the win.

Elsewhere, Wales have named a full-strength outfit according to head coach Danny Wilson as they look to avenge last year’s 11-6 defeat to Ireland.

Welcoming Mike Ruddock’s Irish contingent will be five starters who finished third at last summer’s Junior World Championships, including three more on the bench.

In contrast Ruddock has named an almost unrecognisable XV from that which came third in last year’s tournament, with just two survivors in the startling line-up for the game at Colwyn Bay.

And completing the fixture list is a tie between last year’s runners-up France and bottom-placed Italy who didn’t record a single victory in their 2011/2012 campaign.

The last time the two sides met in the RBS 6 Nations, France ran out 19-5 winners at Stade Battandier-Lokowiak but face the more daunting prospect of travelling to Sicily this evening.

France will be captained by Toulouse hooker Christopher Tolofua – the only full international featuring in the first round of Under-20s matches. Tolofua made his senior bow last summer in Argentina and will provide a huge ball-carrying threat for Les Bleuets.
