Sampdoria President Riccardo Garrone believes Antonio Cassano's problems lie in his upbringing.
The Blucerchiati have asked that Cassano's contract be rescinded after he behaved disrespectfully towards Garrone last month.
"There was also a good relationship with him," Garrone said. "He only respected me at the club. He had questions about the general manager, questions with the Coach and so on.
"It's because he is bad-mannered. He has never been polite and until the age of 15 he was a little delinquent. He even says so in his books.
"It's difficult to understand. He is a fragile and complex character.
"Unfortunately given what has been done, I can't but maintain this line."
