Why is Atletico Madrid called the Sheets Team?

Before explaining the answer, we need to look back at an old story about Atletico Madrid: In 1903, the club was originally a branch club of Athletic Bilbao, wearing blue and white jerseys at that time. In 1911, the team changed to the current red and white vertical striped jerseys and dark blue pants (so the club is sometimes called Los Colchoneros (Spanish for "mattress makers"), because most of the bed sheets in Spain at that time were red and white) vertical stripes).

The "Sheet Army" has gradually become the nickname of the La Liga club Atletico Madrid. Nicknames: ① "Sons of Poseidon" ② "Colchoneros" ("Colchoneros" means "people wearing sheets") One of Spain's traditional top three, its stadium is located in the slums of Madrid, and the fan celebration venue is located in Poseidon Square, so it is called "Son of Poseidon", fans regard Real Madrid as their enemy. And because they were separated from Bilbao, they inherited the red and white sword-striped uniforms. This was the color of the bed sheets in Spanish hotels a hundred years ago, so they were named "The People in Bed Sheets".
