Athletic Club, affectionately known as Los Leones, is not just a football team; it is a symbol of identity for many in Bilbao. The passion of its supporters manifests in every corner of the city, where traditions have been forged over decades, creating a special connection between the club and its people.

One of the most emblematic rituals occurs in the lead-up to matches at San Mamés. The streets fill with fans wearing the iconic red and white jersey, carrying flags and scarves. Euphoria begins to build, as nearby bars and restaurants become meeting points where chants resonate in the air. The famous phrase "¡Euskal Herria, Euskal Herria!" is often heard, a reminder of the regional pride that accompanies each match.

As fans arrive at the stadium, the atmosphere transforms. Supporters gather in the stands, creating a sea of red and white. San Mamés, known as La Catedral, comes alive when the first chords of the chants rise. One of the most moving moments is when the Athletic anthem is sung, with each supporter singing with palpable emotion, uniting everyone in a single chorus that echoes in the heart of the city.

The derby against Real Sociedad is undoubtedly the highlight of the season. The rivalry goes beyond football; it is a clash that symbolizes Basque identity and pride. The week leading up to the match, the city comes to a standstill. The tension is palpable, and fans begin exchanging comments and predictions. On derby day, the atmosphere is electrifying: the chants intensify, and every play is lived with an intensity only derbies can generate.

One of the most cherished traditions is the ritual of the "txistorrada," where fans enjoy delicious grilled sausages before the match, accompanied by good wine or cider. This moment becomes a celebration where supporters share laughter and anecdotes from past matches, strengthening their connection to the club and to each other. The unity is palpable, and the sense of community grows, regardless of the outcomes on the pitch.

During the match, support for Los Leones is unwavering. Each time the team scores, the cheers are deafening, and the celebration turns into a sea of hugs and joyous leaps. In contrast, when things are not going well, fans maintain their support, urging the team to keep fighting. This unquestionable loyalty is what defines Athletic Club supporters.
