Do people actually believe that Dybala is a generational talent or something? He is not, he falls to same category as players like James Rodriquez, Di Maria, David Silva, Özil etc, those type of talents/names are comparable to Dybala and they're definitely replaceable, but not with the names we're associated with.
Dybala is celebration + name + the way he plays, a small brand and if someone is willing to give us 80m for that and is willing to make him their number 1 guy, i think it works for both but it ain't happening at Juve, so why people would get upset about not having a possibility to play under Sarri etc? We all know that Ronaldo is the guy, he has the freedom and Dybala isn't going to get the same freedoms so therefore, his end product won't be good enough and when he isn't scoring, there's no really use for him because he can't really do anything else - even if that.
