With Atlético, he won three regional championships (in 1921, 1925 and 1928), the first in the club's history, and reached two finals of the Copa del Rey (in 1921 and 1926), both of which were lost against Athletic Bilbao and Barcelona, respectively.

It can be said that Triana along with teammate Luis Olaso in the 1920s, contributed to turning Atlético Madrid into an important team in the capital.

Monchín Triana's role in that historic title was modest, but nonetheless a great performance, since he only played three league games in which he scored three goals.

Triana scored two goals against Catalonia in the infamous final of the 1923-24 edition, which ended in a 4-4 draw, losing the replay 2-3 two days later.

During one of the "sacas" carried out by leftist militiamen of the Frente Popular, on 7 November 1936, Monchín was taken out and shot, as part of the Paracuellos massacres, and his two brothers were also killed.
