“I look at him and he is 6ft 3in, he is built like a heavyweight boxer and he can run very fast,” Martin added.
“He displays unbelievable courage and technique on the ball, and just the amount of growth he has had this season. He’s an incredible learner and he’s incredibly brave with the way that he plays.
“He will play at the very top, no doubt about it. He will be a huge asset financially at some point.”
