Twenty-four teams competed in the league, twenty-two returning from the 2018–19 season and two promoted from the 2018–19 Primera B Nacional (Arsenal and Central Córdoba (SdE)).
On 7 March 2020, Boca Juniors won their 34th national league championship in the last round after they defeated Gimnasia y Esgrima (LP) 1–0 and, simultaneously, Atlético Tucumán and River Plate drew 1–1.
[2] On 28 April 2020 AFA announced the abandonment of the Copa de la Superliga and the culmination of the 2019–20 season in all of its league competitions due to the COVID-19 pandemic.
Unlike the previous season, in which only the league matches were considered for international tournaments qualification and relegation, in this season Copa de la Superliga first stage matches would also be taken into account, for a total of 34 games.
The total tally is then divided by the number of games played in the top flight over those three seasons and an average is calculated.
