Cassano also states he should be replaced by Fiorentina coach Vincenzo Italiano.
He said on Bobo TV: "Most likely Allegri will leave, they have to blow him up, Juve can't play like that s****.
"Italiano, I would consider him for that bench. Juve have the strongest team of all together at Inter and he can't make these figures here.
"He wants to stay and he's saying it, but can Juve keep him? I would leave him at home, to restart with him you need an impressive team, where the players do everything by themselves. Allegri is spreading the usual rumours through his friends, his servants, as (Daniele) Adani calls them.
"(Cristiano) Giuntoli I'm sure that if he arrives, the first thing he does is change coach. Otherwise he doesn't go to Juve. The club just has to send him away."
