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..
What to expect from Ronaldo by Spalletti? I don't think Ronaldo will make much of an impact, maybe it will only add to Spalletti a new problem. His nature at Man United should know what will happen if he brings in Ronaldo.
I think it will be more trouble than profit. If Ronaldo's price is still expensive, of course it will not be worth the gain. I think Napoli are better looking for a talented young forward. It's not buying an old player who is starting to lose his best strength.
