Insigne still performs some nice assists and has a couple of dangerous shots per game. Just unlucky in some moments.
But yeah, he'd perform better as SS not a winger.
Pretty sure he said he was a fan of Del Piero, don't even remember him saying he was a Juve fan per se.
The kid clearly has plenty of talent, but you need more than talent to succeed and make it to the top. He has superior players in front of him at the moment, so whenever he does get his chance and he doesn't play as well as he'd like, the pressure does seem to get to him. As it usually does when you play for your home-town club.
