He wants to stay at Juventus, yet burns just about every bridge with his tirade.
Openly criticizing some of your teammates, regardless of whether there is truth to it, is just plain foolish and bad for team morale.
Openly criticizing the management, who stood by you last season when every level headed fan wanted you out, is even more foolish.
If anything, Juventus resurrected his career after he embarrassed himself for a year last season with club and country. The management gave him a second chance, and at the 1st hint that he is on the chopping block, he goes on a media rampage against teammates and management. Imagine if Buffon had acted the same way, or Trezeguet, both of whom were on the brink of moves away more than once.
He is a good player and I would have preferred to keep him, but he is not above Juventus. No1 is to blame here but himself.
