"Cassano has good and bad points, like everyone, including me," the Coach told the Gazzetta dello Sport.
"Someone can have a different personality, but tolerance must always be present. In my career I have always given respect to others before expecting it back.
"There are rules in football and one can break through them, but it depends on the degree. It's quite simple. If someone goes over the top, I'll kick him out. But I doubt anyone will do that here."
Cassano famously clashed with Del Neri when both were at Roma and the player apologised in his autobiography for his terrible behaviour.
"We get along famously now," smiled the tactician. "I certainly don't want to limit his creativity on the field.
"It's up to me to understand the qualities and attitudes of every player. Antonio has moments of great personal expression that we need to use for the team. He'll be a crucial figure, but without having to shake off two or three markers each time."
