He didn't deliver passes/crosses with vision like Nelson is currently doing. Ox always had poor decision making. Decision making does look like Nelson's strong point but he also has the ability to turn defenders inside out.
I will say though that the wingback positions maybe easier for pacey players to look better in rather than being an inside/wide forward. You have more space out wide and more movement in front of you. And as a team it improves our width and reduces predictability more than fullbacks and wide forwards did.
Obviously we need to see more from him and pyschologically it's difficult for a young boy to continue their development.
