#2 History and stature

Juventus is historically significant. No great explanation required here. They are one of the biggest clubs in Europe and have been for an eternity in footballing terms.
Previous stars include Zinedine Zidane, Andrea Pirlo, Buffon, Alessandro Del Pierro and Pavel Nedved. And that is just in the last two decades.
Other superstars include Franco Causio - one of Italy's greatest wingers, Giompiero Boniperti - considered among the top Italian footballers of all time, and countless others who have worn the black and white stripes.
Ronaldo is the latest, and a fitting successor to the legacy Juventus carry. There is absolutely no doubt that Ronaldo's choice of club is one hundred percent befitting to him and the club.
