The La Liga team have confirmed the loan signing of Gaston Castillo - brother of the Manchester City striker - from Independiente
Sergio Aguero's younger brother has signed a loan deal from Independiente, the teenager linking up with Segunda side Cadiz.
Gaston Castillo has joined newly-promoted Cadiz on a season-long loan and the Spanish second tier outfit also has an option to purchase the 19-year-old.
Castillo made his debut for Independiente in April but has yet to score in two substitute appearances.
The youngster is expected in Spain on Wednesday, when he will undergo his medical before completing the deal.
