I don't know. Some older Juve fans I speak to always tell me how DP's influence was the exit of Inzaghi. I always thought it was BS they made up on their own, but then I heard the same thing about Baggio, and possibly of some of the others (some may or may not have made it here otherwise) such as Miccoli, Di Vaio, Mutu, Palladino, Giovinco, Diego, Bojinov.
Now these aren't my words, but I hear it from different sources. How they came to these conclusions, I don't know.
Older Juve fans? What, how long have you supported Juve? Pippo sale?

He was sold because he was made absolete by Trez, totally so. You cant have someone like Pippo on the bench, is too valuable for that plus bit of a character. Ale and him werent best friends exactly to put it mildly (so yeah relationship to your star player is a factor), Pippo bit too selfish in the penalty box to say the least, hehe. But the reason he was sold was Trez, pure and simple. Cant compete with Trez, you have no point being around when you can be sold for big bucks as he was.
Baggio sale = Lippi, having a young phenomenon like Ale available just made the sale easier. The rest you mentionned gotta be a joke

Miccoli left because not only because he was dissapointing, even if I liked him, but because he couldnt take the Ibra sale, demanded to be sold and had a fallen out with Moggi. Mutu benched as much as Ale was basically when he was here by Capello. Di Vaio, Bojinov and Palladino I wont even bother with

And you cant honestly tell me we just loaned/sold Gio and Diego because of Ale, you cant be that dimwitted.
And oh, your shortlist: Everyone except Ibra and Baggio Ale is/was superior to basically, just FYI.
