The 26-year-old's contract runs out in the summer, meaning he will be available on a free transfer.
"I met with Lazio yesterday," Antonio Caliendo told La Lazio Siamo Noi. "We took some forward steps, but nothing has been decided yet.
"Things are going well and there is a desire from both parties to reach a happy ending. There could be something agreed by the end of April."
Caliendo also revealed that AC Milan are interested in the Brazil international.
