In addition, the entity is valued at an estimated 1600 million euros. Despite this, and unlike what would happen with Athletic Bilbao, the blue color would continue to be linked to the Madrid club, wearing it permanently on their pants since 1921 to differentiate themselves from the Basque team. In 1912, the former player Julián Ruete (who would eventually also serve as coach) assumed the presidency, taking the last steps to disassociate himself with Basque Athletic, taking advantage of the fact that Spanish football was structured federatively in the first place with the creation of the Spanish Football Federation on September 29, 1913 and secondly, with the creation of the Central Regional Federation on October 20, 1913. Julián Ruete and Manuel Gómez, the club's secretary, made the decision to modify the company's bylaws, since it was an essential requirement, and they registered the club as an independent company in the federative body of the central region. Athletic Madrid would debut these new colors for the first time in competition on January 22, 1911, in the second edition of the Rodríguez Arzuaga Cup, against the Royal Spanish Gymnastics Society.

At first it was planned that the new stadium would bear the name of the club's founder, Joan Gamper, but faced with opposition from the authorities at the time, neymar barcelona jersey the board of directors at the time opted to inaugurate it with a more neutral name: Barcelona Football Club Stadium.. The dependency with the Basque club was not fully settled since in some article its origin from Bilbao was still cited, but those articles that made the club subject to the Biscayan entity were rectified. During the twinning dinner after the game between the two teams, the players from the Madrid team asked the players from the Basque team if they had more rojiblancas shirts. From that moment on, Athletic Madrid could participate in the Spanish Championship (for the first time in its ten-year history), as long as it was the champion of the regional championship, even if it coincided with Athletic Club de Bilbao. At the end of 1909, Juan Elorduy, one of the Madrid Athletic players, made a trip to England, among other things, to supply the two teams with blue and white shirts from the Blackburn Rovers Football Club.

Despite the immediate success of the section by winning two Spanish Championship titles in just two years of life and finishing in the top positions on numerous occasions, it was finally dissolved in 1959 coinciding with the disappearance of the Spanish Championships. of both modalities that gave way to the Division of Honor. The first of them, Juan, does not appear documented until the year 850, almost 150 years after Bishop Laúlfo. A few years later, the Spanish Championships won, in the female modality, by Pepa Chávarri, also from Rojiblanca, were added to this Athletic Club of Madrid tennis showcase. Athletic Madrid, thanks to the support of its equally powerful Biscayan counterpart in its early years, withstood these attacks, welcoming the "orphan" members and fans of those extinct clubs. "Madrid derby". This gradual incorporation into Athletic Madrid of elements foreign to its Biscayan counterpart motivated, first, that it decided to obtain the aforementioned legal personality of its own in 1907 and, later, that it gradually reduced its de facto relationship with Athletic Bilbao, counting since 1917 with a Madrid's own coat of arms, with the bear and the strawberry tree, different from the one worn by Athletic Bilbao.

As for clothing, as in Bilbao, it would be a harlequin shirt, half white and half blue, and blue pants; such as that of the Blackburn Rovers Football Club of England. Shortly after obtaining its own legal personality, in the 1908-09 season, Athletic Madrid finished runner-up for the first time in an official title, the Madrid Regional Championship, played in a league format that was won by the Spanish Foot-Ball Club. On February 20, 1907, Athletic Club de Madrid was registered in the Registry of Associations, obtaining its own legal personality, different from that of Athletic Club, for which reason it ceased to be a branch. Finally, on October 17, 1924, the Athletic Club of Madrid presented the reform of the statutes in the General Directorate of Security with the request signed by Enrique Álvarez de Lara, secretary of the club. At that time, the selection stood out, on the one hand, players like Enrique Mateos, Di Stéfano -who had already won the Ballon d'Or in 1957 and in this 1959 would win the second- and Gento, who had just won their fourth Cup of Europe.
