He played a crucial role in helping the club win the 1914–15 Centro Championship.

[4] In his first season at Atlético, he contributed decisively in helping them win the 1924–25 Centro Championship four points clear of Madrid FC, thus proving he was not too old after all, and unlike what Real might have thought, de Miguel played a further five seasons with Athletic before retiring in 1929,[5] being also pivotal in helping the club reach the 1926 Copa del Rey Final which they lost 2–3.

[6] Like many other FC Madrid players of that time, he played several matches for the Madrid national team during the 1910s and 1920s, however, due to the little statistical rigor that the newspapers had at that time, the exact amount of caps he earned is unknown.

He was part of the Madrid side that participated in the second edition of the Prince of Asturias Cup in 1916, an inter-regional competition organized by the RFEF.

[9] De Miguel also represented Centro in both the 1922–23 and 1923–24 tournaments,[10] and on the latter he scored the only goal in the quarter-finals against Galicia, and he started in the infamous final against Catalonia which ended in a 4–4 draw, but did not play in the replay two days later, and without him the Centro team was beaten 2–3.
