It really isn't. Yeah you can sharpen it, but you can't just learn it. He actually needs to learn how to control it.
He has a static chest or foot, he doesn't have the coordination to cushion the thing. It's not even average, it's poor and I mean poor.
Ronaldos improved from 22 onwards didn't he? Absolutely. What did he improve on? Controlling a football??? No, not at all. He had acquired all the skills which was why he was called a show pony,
He learned how to make better decisions, to improve his physical athleticism enabling him to hit the ball harder. His control was already there.
Glenn hoddle had it spot on, he said young players are being thrown into games too early with focus on physical attributes. He used a wall to hit left foot and right foot and get instant control, Alan ball did the same.
Sorry but if you are waiting for Rom to learn good control you are gonna wait a long time.
