Parma coach Roberto Donadoni was pleased with Antonio Cassano after his brace in victory over AC Milan.
Parma thumped the Rossoneri 4-2.
Donadoni said: "It takes common sense. Of course if everyone thinks they are right and won't even listen to other options, then they will end up clashing. It just requires a little common sense and an open mind.
"Antonio knows that he has to play that role wherever I place him on the field. If he accepts those conditions, then it goes well. If he doesn't, then he's in trouble."
