I know it's been said but the time required for him to accelerate to his max speed is so long that his max speed is practically irrelevant.
For any distance under 10-15 yards he loses on pace to almost every defender we play against. Yesterday there was an instance where he was actually offside, goal-side of the defender, body momentum headed toward the goal-line, and STILL got beat to the through-ball by the defender before the assistant lifted his flag.
I would go so far as to say he is actually slow unless he has >10 yards to accelerate. This is not a question of just bad agility over 1 or 2 yards, he is slow over short-to-mid range distances as well. If he can develop his ball control at pace then maybe he'll be of value to a counter-attacking team, but he just has too many deficits across key attributes for me to believe that he will make it here or in any possession-oriented system.
