Sir Ian McGeechan ranks his 5 best young players in the world

McGeechan said: "I know his father well, so I have followed Cameron's career fairly closely. I like what I see. Tall, rangy, more of a centre than a 10."

McGeechan said: "Jacobson is an all-rounder who captained the Junior All Blacks to victory at the World Rugby Under-20 Championship in 2017 - a powerful ball-carrier and support player with a real presence on the field."

McGeechan said: "Another one off the Leinster independent schools production line (Blackrock College) and one of the standout No 8s in this season's Champions Cup."

McGeechan said: "“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.”

McGeechan said: "You cannot put a price on outright pace. Rees-Zammit has it in abundance, and, combined with his finishing ability, you begin to understand why the hype surrounding him has been so intense. Definitely a possible Lion."
