It's quite interesting to wait for his return to the Serie A League, because as I know that Napoli and Juventus are sworn enemies, in recent years, we know they are always fighting for the Scudeto at a time when coach Maurizio Sarri was still riding Napoli at that time, and Juve with the current coach, Honestly this will make Juventus fans will be hurt if the move is true..
I don't feel Juventus' fans will be too hurt if Ronaldo moves to Napoli, Ronaldo is not a Juve legend, he only played there for a few years, and even if he scored many goals for them, he isn't one of their legends and he can move to their rivals without it being talked about in that way. Ronaldo for example cannot play for Manchester City or Barcelona because he is a Manchester United and Real Madrid legend and their fans love him so much, but in my humble opinion Ronaldo can move to any club in the Seria A, because he isn't a legend in any of the teams there
