The match is the most important U19 occasion since Wales reached the 1999 World Cup final, Bradley Davies' current all-conquering side having now beaten England 13-10, Scotland 48-10, Ireland 31-6 and Italy 32-18. That earns them the chance to shoot for Grand Slam glory in a campaign that kicked off with an historic 27-7 victory over Australia Schools - the young Wallabies' first Test defeat on Welsh soil.
