Very talented undoubtable, would like him back and we can't afford to miss out you are right. But I just get the impression he could be better with a change of attitude or maybe something else that is lacking, I'm not sure, hard to decipher.
I've been watching him very closely at this Euros, he has often done moments of brilliance followed by something sloppy like losing the ball needlessly. I think this is why he hasn't stood out so far in this tournament, the great things he does gets lost in the inconsistency of the errors he makes amongst them.
