I think this is a very intresting issue and I had a few real life debates about it so here is my two cents...
Being a fan of a club like Juventus comes with an unique privilige many fans seem to take for granted even though its anything but, the history and culture of a club like juventus has been built for over a century now making it an institution in the football world rather then just another club, no matter a good it is in the next FIFA/PRO installment.
This privlige that I'm talking about is the thing the makes me the most happy and proud to support a club like this. To know for a fact that some day, many years from now my kids and even garndkids could sit and watch this team still among the elite is a privlige i wont exchange for a momentry gain of few hundred million euros.
Can any fan of one of those Nouveau riche clubs can say the same? This matter should be viewed in a more long term contexe, Juvntus will be there long after those club are back to their natural place
