The striker has long been linked with a return to Brazil in the January transfer window.
“There is nothing to decide. I have always said he would be staying, but people never believed me,” the agent told Globoesporte.com.
“He will carry on playing for Roma as he has a contract there and he will respect it until the end.
“There is no possibility of him returning to Brazil. I have always denied there being an agreement with Corinthians.”
