Esteban Patricio Matus Castro

Esteban Matus came through Audax Italiano's youth system and made his senior debut on 7 February 2022, against Ñublense, starting the game before being taken off at half-time in a 2-1 defeat. He stayed with the club through the 2023 season before a loan move to Unión La Calera in February 2024, where he made 13 league appearances and five in the cup; the loan was cut short in June that year and he returned to Audax Italiano.

Back at his parent club, Matus scored his first senior goal on 27 January 2025, in a Copa Chile tie against Palestino. His form brought international recognition: he had already featured for Chile's under-23 side in 2024, coming on as a substitute in a 5-0 defeat to Argentina at the Sudamericano Sub-23 in Venezuela, and in February 2025 he received his first call-up to the senior national team for a friendly against Panama.

A left-back who plays on his favoured foot, Matus left Chile in July 2026 for Paraguayan side Club Olimpia, reuniting with Pablo "Vitamina" Sánchez, who had managed him at Audax Italiano.
