Former British and Irish Lions had coach and Telegraph Sport columnist Sir Ian McGeechan selects the 10 young players set to take the world by storm.
1. Marcus Smith, 21, England
“I have watched a lot of him. He never looks flustered on the ball, which is the hallmark of a great player and he has been in and around the England squad without yet being capped.”
2. Jordan Joseph, 19, France
“A powerful runner with good hands and a skilful offload game.”
3. Caelan Doris, 22, Ireland
“Another one off the Leinster independent schools production line (Blackrock College) and one of the standout No 8s in this season’s Champions Cup.”
