Guys, Jubentus haven't put the third star on their jersey until they officially won 30. Scudetto. I remember they have marketed it, showing three stars on stadium and they even had that awful looking pink jersey with big star on it, but they didn't wear three stars over their emblem. I think this is regulated by FIGC. They did wrote "30 sul campo" on jerseys, but yeah, who cares.
I've put these jerseys in spoiler if you don't want to look at it, but here you can see that there are no stars at all.
So yeah, don't spoil yourself the fun of that second star. It is a big achievement.
