2017 Chilean Primera División
The 2017 Campeonato Nacional season, known as Campeonato Nacional de Transición Scotiabank 2017 for sponsorship purposes, was the 87th season of top-flight football in Chile. Colo-Colo won their thirty-second title following a 3–0 away win at Huachipato on 9 December. Universidad de Chile were the defending champions.
Format changes
Starting in 2017, the ANFP approved a change from the European calendar season that had been used since 2013 to a calendar year season. The year calendar would have been implemented for the 2017 season, however, it was postponed for one year. In order to manage this transition, the 2017 Clausura tournament, part of the 2016–17 season, was followed up by a single championship in the second semester of the year. The 2018 season will be played as a single tournament, without the Apertura-Clausura system.Teams
