They are not affiliated with FIFA or UEFA, because the Community of Madrid is represented internationally by the Spain national football team.

In the first half of the 20th century, the Regional Centro Football Federation (which encompassed Madrid and the wider Castile region, and organised the Campeonato Regional Centro for the local clubs) selected a representative team for friendly matches, and also participated in the inter-regional Prince of Asturias Cup, winning the competition on two occasions (1917 and 1918) when they were hosts.

As a result, this side included lesser known players such as Joaquín Pascual, Ezequiel Montero, Sócrates Quintana, José Agüero, Miguel Mieg and Saturno Villaverde and captain José María Castell, who was the only player of Madrid FC in the squad.

[4] In the 1918 edition, they were set up to face Cantabric in a two-legged final, and Centro won both games by an aggregate score of 6-3, with the Castilian goalscorers being Feliciano Rey, Gomar, José María Sansinenea (2) and Ramón Olalquiaga (2).

[5] They also had a memorable campaign in the 1923–24 Prince of Asturias Cup, where they beat Galicia 1-0 in the quarter-finals just as Galicia had done to them in the quarter-finals of the previous edition, and then defeated the South team 2-1 in the semi-finals thanks to a brace from Juan Monjardín, and in the final against Catalonia Monjardín appeared to have been the hero once more when he scored early at the beginning of extra time to put Madrid 4-3 up, but with two minutes remaining Sagi-Barba leveled the scores at 4-4, forcing a replay in which Monjardín scored twice, but his efforts were in vain as Catalonia ran 3-2 winners.
