Colo-Colo defeated Unión Española 3-0 on the first date of the Chilean First Division. Arturo Vidal and Pulpo González had a clash in the middle of the game.
The referee had to stop the game and intercede. Vidal returned to Colo Colo (the team in which he debuted in 2005) in the last transfer market and was reunited, 17 years later, with the club where he was born. Jorge Almirón debuted with a victory against Huachipato in the Super Cup.
