Robinho, whose full name is Robson de Souza, is now in his native Brazil, where he plays for Atletico Mineiro, which are based in Belo Horizonte.
Agent and lawyer Marisa Alija Ramos posted on Instagram to state Robinho denies the charges after pleading not guilty on behalf of her client, who did not attend the court hearings in northern Italy.
It said: "On the news involving striker Robinho, in fact that happened a few years ago, we clarified that he already defended himself against the charges, saying he had no participation in the episode".
Robinho was also accused of sexual assault in London in 2009 while at Manchester City but was cleared of any wrongdoing. Brazil does not extradite its own citizens when they are sentenced in other countries.
Under the Italian law, the forward will not be sent to prison until the appeals process is finalised, which could take years.
"Every legal measure is being taken about this first ruling".
He now plies his trade back in his homeland with Atletico Mineiro.
Robinho has won 100 caps for Brazil, scoring 28 goals.
Robinho began his career with Santos before leaving Brazil in 2005 for a three-year spell with Madrid.
