On 12 January 2020, Valverde tackled Álvaro Morata during the Supercopa de España Final against Atlético Madrid, committing a professional foul and stopping play with Morata clean through on goal. Valverde was sent off, but his actions stopped what was an inevitable goal, forced a penalty shootout which Real Madrid won, and earned him the Man of The Match award and widespread praise. Atlético Madrid manager Diego Simeone later referred to the tackle as "the most important play of the game". He made 33 appearances during the league season, as Real Madrid won the 2019–20 La Liga.
