The son of Ronaldinho, Joao de Assis Moreira, has been training with Barcelona's youth team.
Joao de Assis is a forward who can play both upfront and as a playmaker. He is a skilful right-footed player who can use both of his feet.
His father thrived at the Blaugrana, winning two LaLiga Santander titles and the Champions League trophy in 2006.
Mundo Deportivo says the 17-year-old has been in Catalonia for the last 10 days in his bid to join Barcelona, where he hopes to stay after leaving Cruzeiro.
Barcelona president Joan Laporta is personally involved in negotiations with Joao's uncle and agent Roberto de Assis, who has accompanied his nephew in the Catalan capital.
