He has played 3 games against men.
It’s not about balls, or the lack thereof.
It’s not about height, of the lack thereof.
It’s about giving someone, who missed a chunk of football last year - and had only played against people his own age before that - an opportunity to develop his game, get used to the heavier collisions when playing men and get the confidence that he can make that next step.
I have no doubt he’ll make the next step with aplomb, but rushing him is in no one’s best interests, particularly Jye.
