However, Brazil does not extradite its citizens, and Italy said Robinho should serve his sentence in his home country.
The footballer, who protests his innocence, told Brazilian network TV Record in an interview broadcast on Sunday that the sex was “consensual”.
“I never denied it (the encounter),” he said. I could have denied it because my DNA wasn't there, but I'm not a liar.”
He also accused the Italian justice system of “racism”.
According to the complaint, Robinho and his co-accused made the young woman drink alcohol “to the extent that she became unconscious and unable to resist” and then had sexual intercourse with her “multiple consecutive times”.
In March 2021, the Milan court published its reasoning for upholding the original conviction, stating that Robinho “showed particular contempt for the victim, who was brutally humiliated.”
Robinho's case and that of former Barcelona and Paris Saint-Germain defender Dani Alves have sparked criticism over the failure of football authorities to condemn violence against women in Brazil.
In February, former Brazil international full-back Alves, 40, was sentenced to four and a half years in prison for raping a woman in a Barcelona nightclub.
