Napoli never ever wanted to sell their key player to their rival. That's why selling him to the Juve is just a dream. They even restricted him on their agreement with Galatasaray to never sell him to the serie a club. That's why his move to the Juve was impossible.
I have no problem with Napoli not selling Victor Osimhen to their rival because they know what Victor Osimhen is capable of doing, and if they sell him to Juventus, Juventus might become a Scudetto contender overnight. Napoli restricting Galatasaray from selling Victor Osimhen to any Serie A club shows that they are mean, and it is not a good sign of sportsmanship.
