Robinho is expected to follow in the footsteps of Ricky Kaka, who signed for Orlando City last week.
"There has been a formal offer from Orlando City, as confirmed by Adriano Galliani," representative Marisa Ramos told Globoesporte.
"The two parties are negotiating. If this move does go through, moving to Brazil for six months first is certainly an option. He couldn't stay for six months without playing.
"His contract with Milan expires in 2016 and discussions are at an embryonic stage. He could be loaned to Orlando City or even sold. We'll listen to the proposals and see what is to be done."
