In the 2017 season, El Rojo achieved international glory by capturing their second Copa Sudamericana title, defeating Flamengo 3-2 on aggregate after a memorable 1-1 draw at the Maracana Stadium. A major highlight was 18-year-old talent Ezequiel Barco ice-cold penalty to equalize in Rio. Domestically, the squad maintained a strong competitive form in the Primera División, securing a 6th-place finish with an impressive defensive record, conceding under a goal per game.
