Completely agree. The main areas which I think is important is technical ability, dynamism and agility. All these are fundamental for a central midfielder and I believe Kone has that in abundance.
His intelligence on and off the ball is evident. One or two touch passing, good positioning and reading of the game, range of passing and mobility. I think he will do well if given the chance unlike some of the midfielders United currently have who either have no mobility, treat the ball like hot potatoes, and incapable of controlling games. Physicality is good but you don't neee to be built like the Hulk to succeed. Kone will be fine.
