obviously there are rules and the rules must be respected
otherwise it would be anarchy
using this kind of punishment when you transgress are excellent
fines are also excellent for making it clear that the rules must be respected
Well this is what should be done now. Juventus already know that when they violate "again" then the sanctions given will be much bigger than this, hopefully they don't get caught up in the same thing again and they really do it cleanly, of course with the existing fairplay.
They are good enough now and they are one of the big clubs in Serie A so it would be very unethical if they again destroyed their name with their stupid behavior just for the sake of short profits.
I would guess that the best thing to do for Juventus would be following all the rules they possibly can. Otherwise the next punishment will not be so easy and they might find themselves relegated all over again.
We have seen them recover better after that, I mean nearly what 10 cups in a row or something after they were relegated? That was a serious improvement for sure but they wouldn't want that again. It's better to stay here and get better, which they will, then go down and get batter later on. They lose so many players and time during that period, which could be used to dethrone Napoli and take back the title again in a few years at most. For that, they need to never do anything remotely shady again.
