The 30-year-old, who scored four goals last season for Milan, is widely expected to leave the San Siro this summer and has been linked with a number of European and South American clubs.
Galliani has rubbished reports linking Robinho with a switch to Turkish side Besiktas, but has confirmed that Olympiakos have bid for the former Santos man, while a host of clubs in his homeland remain interested.
"There are some offers for Robinho from Olympiakos and several Brazilian clubs. He is evaluating them. We will meet again tomorrow afternoon," Galliani told Sky Sport Italia.
"We have not received an offer from Besiktas."
With Robinho's future still in the balance, the Milan chief insists his side will replace Robinho if he does depart the Italian club.
"We are looking for a wide striker if Robinho leaves. (Manager) Pippo Inzaghi wants left-footed players on the right side."
