The Brazilian forwards are set for a January exit, with both likely to return to their homeland.
Robinho is subject to offers reportedly from Fluminense and Flamengo, with Corinthians keen on Pato.
“My trip to Brazil has been planned for months. It will be all work and no vacation, as there are two negotiations in progress,” said Galliani.
“Pato and Robinho asked to leave Milan. I already know what could happen in case they do go.”
