However, Caliendo says the Napoli president will welcome the battle.
The former agent told TeleClubItalia: "I do not want to intrude on Raiola's thoughts and ways of doing, but I can only say that I think it is quite dangerous what was stated about Sarri.
"We all know the Napoli coach is of the highest order and inevitably that there is Mino who uses these systems to break relationships and put clubs in trouble.
"Weaker ones or people with tiny wrists fall as often as they do, but this is not the method they can use with De Laurentiis. The president is strong and when he is challenged he enjoys it even more. Raiola did not understand that this is not a winning strategy, that is, it is only for the economic interests of his and his assistants."
