Here, Lions legend Sir Ian McGeechan spins through three possible candidates to replace Owen Farrell as England’s next number 10.
All three were included in McGeechan’s top 10 young players in the world.
1. MARCUS SMITH (Harlequins)
McGeechan said: “Smith’s progression from Brighton College 1st XV to the Harlequins 1st XV was rapid and well-timed, with Nick Evans stepping back to coach.
“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. But one to watch, certainly.”
