In 1987, Universidad de Chile disputed the last places in the honor series, while the official bar at that time, Imperio Azul, commanded by Eduardo Martínez, young fans, mostly of the thrash metal and punk style, who participated in it began to gather and they stood below it, glued to the fence, singing and encouraging the team with a couple of canvases with the text "Devotos del Bulla" and "Con la U Siempre", which broke the traditional scheme by incorporating phrases referring to the identification of the fans towards the team.
Before this, the classic was played with Colo-Colo, where Los de Abajo obtained as a trophy a large flag that belonged to the White Claw.
This type of action had no place in the fan fees of the official bar, so the return of the aforementioned flag to its legitimate owners was requested.
The stadium's capacity was of 20,000 but 25,000 supporters of Universidad de Chile (football club) travelled to witness the end of the title drought.
On the other hand, Pinochet was honorary president of the archrival Colo-Colo, and many universidad fans think that he helped on the building of the stadium with government funds, though they have no proof of this and actually that was only a presidential campaign promise.
Also, in 1999 they opened the "Escuela Libre Los de Abajo", a free school for teens of low-class and people that didn't finish their basic grades.
