This was Atletico's first defeat in the opening game of a new LaLiga season since 2009. Simeone acknowledged the loss, saying it hurt, but he chose to focus on the positive aspects of the game.

He praised the team's performance until the 60th minute, highlighting their character and determination. However, he also acknowledged that the team's performance declined after making some substitutions.

Simeone took responsibility for the decline, saying it would teach him a lesson. He also downplayed Alvarez's reaction to being substituted, saying it's normal for players to get angry when they're playing well.

Despite the disappointment, Simeone emphasized that the team would learn from the defeat and use it as an opportunity to grow. He stressed that winning is what matters, and he couldn't be satisfied with a defeat.
