Diego Sinagra Maradona - the son of soccer great Diego Maradona -- is set to join Argentine third division club El Porvenir.

Signing Diego Junior "would not cost the club a cent, but could generate interest and income," said El Porvenir coach Luis Ventura.

The 25-year-old, whose career has been limited to lower-level clubs in Italy, is the offspring of a relationship Maradona had with an Italian woman, Cristina Sinagra, while he was playing with Italian club Napoli.
