I remember watching him when he was 15/16yrs old... a great blend of aggressiveness, acceleration, strength, finishing. He had agility and could even dribble. He had a good first touch.
What I still think happened is he had a growing spurt, got too strong and lost all of it. What a shame.
I do think we could still find suitors in the EPL, given his reputation as having potential. Just antecipate the obligation with Everton now and sell him for 15M. Not happening, sure.. this time next year, will be stuck with him.
