They are not the only ones, with the Uruguay international among the most sought-after talents in European football.
City are, however, one of the few clubs who could afford to put a transfer package in place which may tempt Napoli.
They have stubbornly refused to contemplate selling up until this point, but may be forced to reconsider that stance if big money is offered or the player expresses a desire to move on.
Should such an event occur, City can be expected to be among those leading the hunt for Cavani's signature.
"I don't know if the club will lay siege to Napoli for Cavani, but every club with a player of the highest level will be courted by bigger clubs," said Gregucci.
"(Roberto) Mancini decides the transfer targets with the new directors.
"If Cavani should want a new adventure, I expect they'd let him go."
