[1] Together with Arthur Johnson, Pedro Parages, Federico Revuelto, Antonio Neyra and his two brothers, Mario and José, he was part of the historic Madrid team that played in the first-ever Copa del Rey in 1903, netting two goals in the opening match against Espanyol (4–1) on 6 April 1903, with the first of which being the very first competitive goal in Real Madrid's history.

[5] Those two goals against Club Español were enough to earn him the tournament's top scorer accolade tied with Juan Astorquia and Alejandro de la Sota.

[6] Español de Madrid won the 1903–04 Campeonato Regional Centro, hence qualifying to the 1904 Copa del Rey, which ended in controversy as they were unable to participate in the final, meaning Athletic were declared winners again.

He played an important role in the club's triumphant campaigns at the 1906 and 1907 Copa del Reys, featuring alongside his brother in both finals.

[9] In 1910, the two Giralt brothers and Antonio Neyra joined RCD Espanyol, and Armando once again proved his quality by reaching his third cup final in a row, which also ended in a loss to Athletic Club.
