I agree, he wasn't excellent yesterday but he was definitely competent and there were was a few little glorious touches that just hint at what he's capable of. Not bad considering it was his full debut and he was against one of the biggest and most in-form teams at this level. As others have indicated, I'd be surprised if Silva was any better at the same age. Likewise someone like Xavi.
It's the little things he tries that make him stand out. He does those scooped sand-wedge passes that you see people like Messi and Xavi do all the time and you think 'why don't other footballers do that instead of trying to pass it through the defender?', and the answer is that most just simply don't have the technique, vision or talent to do it. He does.
He's clearly a special talent and if we give him time in a couple of years he could have quite an authority to his play and who knows how far he'll go.
