Cagliari president Massimo Cellino insists he won't break up his squad.
Davide Astori and Radja Nainggolan have been linked with moves away this week.
"I refused 15m for Astori because as a player he is too important to us," said Cellino. "I want to keep him even if a big club wants him.
"I doubt Napoli will want him anymore. Roma? I don't know much about that.
"I don't want to lose Nainggolan either - that is the last thing I want to see."
