It may not be the €23 million transfer to Atlético Madrid that Sergio Agüero completed days before his 18th birthday in 2006 but Gastón del Castillo is following in the footsteps of his famous older brother and leaving Independiente for Spain.

Segunda División side Cádiz have taken the 19-year-old on a season-long loan deal with the option to make the move permanant for a fee of €2.25 million should Del Castillo impress at the Estadio Ramón de Carranza.

After a deal with Italian club Crotone fell through earlier in the transfer window, it wasn’t clear that Del Castillo would be leaving Avellaneda despite seeing his route to Gabriel Milito’s first team being blocked.

However, Cádiz have provided a path to continue his development outside the Estadio Libertadores de América and the youngster must now attempt to come out of his older brother’s shadow.

Despite scoring regularly for El Rojo’s youth sides and representing Argentina at under-20 level, the comparisons with Sergio Agüero were inevitably frequent but rarely helpful with the Del Castillo never likely to achieve the highs of one of Argentina’s most prodigious talents.

The physical similarity is startling as is their build and style of play but while Sergio burst into the first team as the youngest player to do so in the Argentine top flight at the time, Gastón del Castillo has had to make do with just a couple of fleeting substitute appearances last season.

Quick and tricky with a low centre of gravity that allows the 19-year-old to turn inside defenders, Del Castillo hasn’t shown the same ruthlessness in front of goal that his brother exhibited and still does for Manchester City.

However, that doesn’t mean that Cádiz’s latest signing cannot have an excellent career in Europe. There is still a great deal of development required and with a contract at Independiente that runs until June 2018, a return to Avellaneda is not to be ruled out.
