The now Barcelona striker said: "When I came to Juve I had a problem with my back but I wanted to play at once.
"When (Carlo) Ancelotti became manager I began to play all the games.
"Then something happened with Moggi which I didn't like - I don't want to go into detail. My character came out because I am an honest lad and, for me, it was a case of disrespect.
"If that hadn't happened, I would probably have continued to play for Juventus. But after this lack of respect I told them I didn't want to play there anymore and so I left."
