World Cup 2019: 6 Young players to watch in Japan

Here, RUCK picks out the 5 young players who are worth watching out for in Japan.

The 2019 Six Nations marked the breakthrough tournament for Curry, topping the tackling charts (86) and attending more rucks than any other player in the competition (177). Already tipped by Sam Warburton to become a world-class back-rower.

At just 22, the powerhouse is already one of the more established names inside the Argentina camp. Called up to the squad for the first time at the age of 18, the Jaguares flanker already has 24 caps to his name, including starting the Pumas' first victory in Australia during the Rugby Championship.

The potential he possesses is enormous. A star for the U20s, the now 21-year-old tighthead saw a swift elevation to Test duty despite playing in the ProD2. An explosive carrier and a willing worker.

This 22-year-old flying Scotsman has enjoyed a rapid rise to prominence in Gregor Townsend's squad since forcing his way into the side less than 12 months ago. Blessed with explosive pace and a happy knack for finding gaps, Graham could be key to helping the Scots navigate their way out of a tricky group.

The Gloucester back-row beat an incredible 19 defenders in his first three matches of 2019 for the Azzurri. These stats won’t come as any surprise to regular watchers of the Premiership – he beat 56 defenders in just 677 minutes of action last season and completed 96% of the 122 tackles he attempted.

Given his opportunity during England's tour of South Africa last summer, Nkosi announced himself on the international stage with two tries during the stunning comeback victory. Since then, he has holds a near 100 per cent strike rate in Test rugby, scoring in four of his last five Test starts, only failing to cross over against the Scots at Murrayfield.
