Both players have been linked with a return to Brazil.
"Santos may be interested in Robinho, but it is not our intention to sell," said Galliani.
"There are no offers for any of our players at this point in time. I think that Pato is on the mend and everything has been cleared up with his agent.
"There are 32 players in the squad and if nobody leaves then nobody will come in. We'll have to sell first and then buy, otherwise we'll stay as we are."
