I know there are some peeps here that would replace the Juve squad with only Udinese players (Armero, Isla, Benatia, lol), but that's not me.
No doubt Neymar is quite a bit more talented, but I don't fall for just mere talent. When I see him, I see a player whose mercurial ability gives him a clear advantage over a player like Jovetic. But by virtue of his personality, Jojo is overcoming having "only" 50% of Neymar's talent and making himself an important player, which I think could take him much further.
I don't know much about Neymar - only seen him a handful of times - and I'm not trying to undermine him, but the difference in talent between the two doesn't make it as obvious to me as it is to you that he'd turn out to be the better player.
