I love when he nonchalantly chips it over an opponents head to a teammate just 5-10 yards away. Did it a couple of times last night. The opponent thinks he has his angles covered, and he does, but Pirlo operates in higher dimensions than most players. He's literally got every pass in his locker.
It is because he pulls of difficult stuff with ease. He has also very much flair for someone who is not dribbling much.
+ he seems to not give a fuck about anything.
