Juan Padrós was elected to the Constituent Assembly as the first official president of the club and took charge of the probate proceedings of the society, whose first office was installed in the back room of his own trade of Alcalá.
The first meeting of the new formed club took place just three days later face among themselves members of the entity, divided into two groups: blue and red. Juan Padrós, sided with the former, while his brother was the referee of the match.
After creating the new club, the efforts of the brothers parents focus on the implementation of a national inter-club championship. The Championship of Spain was organized by the club, always with the help of his brother Carlos, then chairman of the regional federation.

After a long period away from the football matters, the name of Juan Padrós returned to the present in July 1911, when the assembly of the Spanish Federation of Foot-ball Clubs asked him, as president. The pressures did, finally, Padrós to accept the position on an interim basis that had rejected a year earlier. His term lasted only one year, long enough to achieve the reunification of Spanish football around the Royal Spanish Football Federation, founded in September 1913.
