Why are people so concerned about his dribbling and close control? Messi and Hazard go past players with unreal close control and small bursts and agility. But in reality, there are few like them. Ronaldo became twice the player when he stopped dribbling and doing fancy flicks and instead used his superior speed to go past people. Nani is an even better example. Prior to his best season at United, he would stop and try to dribble past players. When it worked, it looked godly. When it didn't, it looked stupid and pointless. When he became more direct and chose to instead run past them, his game improved. Valencia at his best was unstoppable not because he could dribble like Messi, but because he had so much speed and strength that there were hardly any fullback who could compete with him. James looks to have even more acceleration and about equal top speed. He isn't agile like hazard, but he is much faster. Both styles can be effective.
I look forward to seeing him play and what he can offer.
