The 2019 Liga 1 de Fútbol Profesional (known as the 2019 Liga 1 Movistar for sponsorship reasons) was the 103rd season of the highest division of Peruvian football. A total of 18 teams competed in the season, with Sporting Cristal coming in as defending champions. Binacional were the champions, winning their first league title by defeating Alianza Lima in the finals by a 4–3 aggregate score. Competition format The season will be divided into three stages: Torneo Apertura, Torneo Clausura, and the Playoffs. The first and second stages will be two smaller Apertura and Clausura tournaments of 17 games each. Each team will play the other teams once during the Apertura tournament and once during the Clausura tournament in reversed order for a total of 34 matches. Points earned during the Apertura will not carry over during the Clausura. The winners of the Apertura and Clausura stages will qualify to the playoffs along with the top two teams of the aggregate table, as long as they end in the top nine of this table at the end of the season. The playoffs to decide the national champion will be contested by four teams, which will play two semifinals with the winners playing the final. In every stage of the playoffs, the teams with the most points on the aggregate table will choose which leg they play as the home team. If the teams are tied in points after the two legs of the final, a third match on neutral ground will be played to decide the national champion. If a team wins both the Apertura and Clausura, the playoffs will not be played and that team will be declared as champion. Qualification to international competitions will be as follows: the top four teams of the aggregate table will qualify for the 2020 Copa Libertadores, while the next three best teams in that table will qualify for the 2020 Copa Sudamericana, with a fourth berth being allocated to the 2019 Copa Bicentenario winners. In case the Copa Bicentenario winners have already qualified for an international competition, the eighth best team in the aggregate table will also qualify for the Copa Sudamericana. The two teams with the fewest points in the aggregate table at the end of the season will be relegated. Teams A total of 18 teams have been confirmed to play in the 2019 Liga 1, an increase of two
