9. Emiliano Boffelli (Jaguares/Argentina)
This product of the Argentina youth system, Boffelli represented his country at U18, U19 and U20 level before a knee injury threatened to sideline him indefinitely.
But he came back stronger and quicker than ever and made his full international debut for the Pumas this year. Capable of playing all positions in the backline, the gifted footballer has settled down very well on the wing for the Argentinian national side in 2017.
Good on the air, solid on defence and capable of nailing long distances goal kicks, the 22-year-old is a great asset for the Pumas and has a bright future ahead of him.
10. Zach Mercer (England/Bath)
What can you say about the charismatic 20-year-old that’s not already said? Yes, there are the flash things- like the amazing offloads and tries. But there is more to Mercer’s game than that.
Many people’s U20 player of the tournament, Mercer is one of the most exciting English prospects in a long time and is now serving as an apprentice with Eddie Jones squad during the Autumn Internationals. 2017 was a great year, but hopefully, 2018 will be even better for the youngster.
