The table lists the position after each week of matches. In order to preserve chronological evolvements, any postponed matches are not included to the round at which they were originally scheduled, but added to the full round they were played immediately afterwards.

Champions League
Following the abandonment of the 2019–20 Primera División due to the COVID-19 pandemic, Barcelona and Atlético Madrid were selected by the RFEF to take the two Spain slots in the next year's Champions League. Due to Spain's high ranking, both teams entered in the knockout phase (round of 32), rather than go through qualifying.
