The 28-year-old Brazil international claimed former club Santos are not the only club keen to capture his signature during the next transfer window.
"Milan do not intend to sell me and are certainly a club that have opened the doors and given me an opportunity," Robinho told Gazzetta.it on Monday.
"I have a history with Santos and with me it will be easy to agree, but there are other Brazilian clubs who are talking with AC Milan and with me.
"My love with Santos is eternal but they are a professional side and see what is best for me."
Milan face Reggina on Thursday at the San Siro following their 4-2 win over Torino in Serie A.
The Rossoneri suffered a blow during that match as midfielder Nigel de Jong ruptured the Achilles tendon in his left ankle and will be out for the rest of the season.
