Robinho will be a free agent in July after Milan agreed to release the Brazilian forward early from his contract at San Siro.
Brazil international Robinho has been released from his contract at Milan one year early.
The 31-year-old forward joined Santos on loan in August 2014 after falling out of favor under Milan head coach Filippo Inzaghi, and he is expected to sign permanently with his boyhood club now that he is a free agent.
Robinho's return to Brazil produced 12 goals in all competitions, form that has earned him a place in Brazil's provisional squad for the forthcoming Copa America.
