Inter Milan president Massimo Moratti feels Juventus counterpart Andrea Agnelli feels he needs to fire out insults to win approval from fans.
The pair were involved in a slanging match over Calciopoli last month, but the Derby d'Italia was remarkable for its sense of fair-play.
"When certain insults arrive, I classify them as authentic shots. But I have known Andrea since he was a boy and there is also affection.
"I believe that some of his attitude is imposed by the role that he occupies and the relationship he has to keep with the fans," said Moratti.
