Gonzalo Castellani

Gonzalo Pablo Castellani (born 10 August 1987 in Buenos Aires) is an Argentine footballer who plays for Chilean club Colo-Colo as a midfielder.

Club career
Castellani started his professional career with local Ferro Carril Oeste, competing in Primera B Nacional with the Buenos Aires outfit. On 2 January 2010 he moved to Spain and signed for Villarreal CF, being assigned to its B team in Segunda División; he failed to make any appearances for the club during the season, due to the team's excessive number of foreign players.

Castellani made his official debut for Villarreal B on 16 January 2011, starting in a 0–2 away loss against Recreativo de Huelva. On 18 December he first appeared in La Liga with the main squad, replacing Cani in the 64th minute of a 1–2 defeat at CA Osasuna.

On 6 July 2012, after both squads' relegation, Castellani joined Godoy Cruz in his native country. Two years later he moved to Boca Juniors, also in the top division.

In March 2024, he returned to Chile after his stint with Unión La Calera in 2022 and joined Colo-Colo.
