Cassano: Del Neri will improve Juventus
Samp qualified for this season's Champions League with Del Neri in charge last term.
"Del Neri is a great tactician and the team they are building for him is perfect for his ideas," said Cassano.
"You'll see that in May if they are not on top of the table, they'll be right up there with Inter. Behind them I see Roma and Milan on level terms."
