What crime did he do at that time? And how come he's only serving his prison sentence now?
Gangrape and it is only now because he fled Italy before getting arrested.
Robinho has never been a legendary player in Brazil or over the world. He used to be considered as a next Pele, and he was talented but his career has never reached to Pele level. There are other players from Brazil are better than Robinho from Juninho (Lyon), Kaka, Adriano, Ronaldinho, Ronaldo, Fabiano, Neymar, Vinicius and Rodrygo.
He was mediocre at best compared to the rest, he is nowhere near the top goalscorers for Brazil while he played and neither was he at Milan, even when Milan won the scudetto, there was Zlatan, Pato, Balotelli and even Nocerino who were scoring more than him.
