Former Juventus chief Luciano Moggi believes a row with Max Allegri sparked Leonardo Bonucci's move to AC Milan.
Milan have signed Bonucci for €42m.
"It's a great buy for Milan, as he is the best defender in Italy at this moment," Moggi told TMW.
“Evidently something happened between him and the Coach. Even then, I never would've given him to Milan, because they are a direct opponent.
“I'd have told him: 'I will sell you abroad, otherwise you can stay here and not be a pain in the…'
“I don't believe in club symbols, as they are all professionals. In any case, Bonucci is a big reinforcement for Milan."
