Manuel Rodríguez Arzuaga

Manuel Rodríguez Arzuaga (1876 – 5 September 1952) was a Spanish versatile athlete and a football executive. He is widely regarded as one of the most important figures in the amateur beginnings of Atlético Madrid since he was one of its founders in 1903, a vice president between 1903 and 1905, and the club's first-ever patron. He invested most of his own capital in Atlético, saving the club from bankruptcy during its moments of financial difficulties.

His high economic position was fundamental in helping Atlético to build the Campo de O'Donnell in 1913. He was also credited with the payment for Atlético's first red-and-white shirts in 1911, and the club's first-ever match outside of Madrid in Alicante was promoted and financed by him. He was named an honorary president of the club in 1916.

In 1903, he founded a foot race competition in Madrid, which became the most important event in Madrid athletics, and in 1910, he founded a football competition in the same city. In both cases, he donated a trophy to the winner, the so-called Copa Rodríguez Arzuaga, hence the name of both competitions. He also held the position of director of the Spanish Football Federation.

He was an all-round and versatile athlete, playing both football and field hockey for Atlético when necessary, running foot races, and even coaching tennis. He also played rugby in France and football and rowing in England.
