Other noted fans include tennis player Juan Mónaco, actors Jorge and Federico D'Elía, philosopher Darío Sztajnszrajber, journalist Mauro Szeta, human rights activist Estela de Carlotto, filmmaker and politician Fernando Solanas, and sports journalist Osvaldo Príncipi. In the 1983 presidential election, Estudiantes fans were, together with their peers from Vélez Sársfield, the first to voice their support for eventual winner Raúl Alfonsín in his bid against the Peronistas. The friendship with Vélez supporters has since vanished, especially after an Estudiantes win denied Vélez the 2003 championship.

For several years, many chants incorporated the word Tricampeón (three-time champion) because of the Libertadores three-peat. After the 2009 Libertadores final, some of the newer lyrics
