On 27 September, Suárez made his debut for the club, scoring two goals and providing Marcos Llorente with an assist in a 6–1 victory against Granada. On 25 November, Suárez's backheel goal against Mallorca, which he scored on 7 December 2019, was nominated for the 2020 FIFA Puskás Award, eventually finishing in second behind a goal scored by Tottenham Hotspur's Son Heung-min. On 3 January 2021, Suárez scored a 90th minute winner against Alavés, a feat which saw him overtake Radamel Falcao's record for a player's best start with Atlético this century; his eleven goals contributions (nine goals and two assists) in his first twelve La Liga matches surpassed Falcao's nine goals and one assist over the same period in 2011.
