No, but I am visiting our games for many many years now and I just can tell you that the atmosphere got lower every year. (
@Buck Fuddy please confirm)
Every year we raise our prices. Instead of signing people creating a great atmosphere there are tourists and spoiled kiddis of rich people playing on their phones during the game. It's a trend which goes hand in hand with our ticket prices. What do you expect from a normal singing italian Juventus fan who used to visit our games for 50-70 Euros and suddenly has to pay 120-200 (Yes, tickets against napoli are up to 200 Euros!!). He won't come, because he simply cannot afford it. Italians with a regular job don't earn that much money.
And what are you expecting from our Ultras? If we continue to raise the prices, they won't be able to afford their season ticket either. That's why they go on strike. I can understand it, but I think it's too late now anyway.
