We cannot feasibly do what United and PSG do though, not even close. I'm sure Agnelli is well aware of this though.
I have to say I liked our sale policy and I think Bonaventura would've been an improvement to our squad (we're thin as fuck at midfield).
Ticket prices? Maybe as a start, but that's nothing in my opinion, there's still a long way to go. I don't want this to become just a club full of mercenaries. The first thing I thought of was when Buffon went through that period after a big injury a few years back and going through a period of very poor form, where people here were calling for his outright sale but instead we stuck by him and showed faith in him. Of course, he promptly delivered and such morons went quiet. If we were in the same situation now, would we do the same thing?
