Mario Cáceres

Born in the capital Santiago, Cáceres made his debut for Colo-Colo in 1998, but spent the following years on loan in the country, to Ñublense and Corporación Deportiva Everton de Viña del Mar respectively. Caceres was signed by Sporting Clube de Portugal in January 2001, at the same time as compatriot Rodrigo Tello. Grossly unsettled he returned to Colo-Colo after just a few months, as the Lisbon club refused to activate the buying option it had on the player. At the start of the 2004 season, Cáceres switched for C.D. Universidad de Concepción, but left the following year to Liga MX side Lobos de la BUAP. Before the start of 2005's Apertura, Cáceres moved to another country, transferring to Greek team Aris FC, in the country's second level. In 2006, he rejoined Colo-Colo for a third stint, but returned to Greece and its division two the next year, with Pas Giannina FC. Cáceres found some stability in the 2008 summer, going on to play two seasons at Switzerland's FC St. Gallen. Subsequently, he returned to his country, first joining San Luis de Quillota and going on to represent Audax Italiano, former team Everton and Deportes Temuco.

Cáceres capped for Chile at under-20 level, appearing at both the 2001 South American U-20 Championship and the 2001 FIFA World Youth Championship. He also played for the nation at the 2004 CONMEBOL Pre-Olympic tournament.

He began his managerial career as an assistant coach in the Colo-Colo youth ranks and coach of Cobreloa at under-13 level. From 2018 to 2022, he worked as the assistant coach of Rodolfo Madrid in Rodelindo Román at minor categories of the Chilean football.

His nickname, El Petrolero (The Oilman), was given by the Chilean play-by-play commentator Claudio Palma, due to the fact that he had a hard time picking up speed during the matches, like the diesel cars. His brother, Carlos Cáceres Gómez, is a former footballer who played in Indonesia for PS Palembang and current football coach who has worked for clubs such as Cobresal (women). In 2015, he worked as a football commentator for the Chilean TV sports channel Canal del Fútbol.
