The difference between Juve and clubs like Roma and Napoli is if they have a player like Del Piero, Totti or even a legend like Maradona, the player becomes almost as big as the club. For Juve it doesn't matter how great the standing of the players, whether it's a long-term club legend like Del Piero or Buffon, or for example a global superstar like Ronaldo comes in and wins everything in the way he has done before, or as Platini did for the club. In the end it's just another great player in a long list, and onward we go looking at creating the next great player, winning the next set of trophies, creating great teams. It doesn't stop, and that sets us apart.
It might seem like a cold club to be a legend for but that ethic is there from day one, we do the best for players and if they don't want to stay here they can move to another top team, but probably won't find the same. There is more romance and nostalgia at other clubs, but that is because there is also about a tenth as many trophies, great teams, great players and great games to remember.
As far as Juve are concerned the club is number one and you have to look through a telescope to find number two, even the greatest legends we had. When it stops being that way we should start worrying, because it has to be the same way for all elite teams.
