Municipal. Toledo had retired and Comunicaciones had dethroned them at the top of the league, winning it three years in a row. Municipal struggled through an eight-year title drought. They managed to break that drought with three championships in the 1960s (1963–64, 1965–66, and 1969–70), but Comunicaciones remained Guatemala's dominant team, winning seven titles in fourteen years from 1956-72. The Comunicaciones-Municipal match emerged as a high-profile local derby, the biggest in the country. Another rivalry developed with a third Guatemala City club, Aurora, which also won three titles during this time. 1970s: First international success In 1973, Uruguayan coach Rubén Amorín arrived at Municipal. He managed a group of players that included defender Alberto López Oliva, midfielders Benjamín Monterroso and José Emilio "Pepe" Mitrovich, and forward Julio César Anderson. Anderson would become the club's highest ever goalscorer, and help lead the team to its era of greatest glory. Municipal won league championships in both 1973 and 1974 (their first-ever repeat titles). In 1974, the same year that they were marching to a dominant repeat championship, they also became the first Guatemalan club to win the CONCACAF Champions' Cup. The Rojos then went on to play the Copa Interamericana against Argentina's "red team", Independiente. The first leg was played in Guatemala on November 24, 1974, and Independiente won, 1-0. However, Municipal surprised the continent by winning 1-0 in Argentina two days later. The hero was Argentine-born José Emilio "Pepe" Mitrovich in the second half. With both teams equal in points and goal difference, the match went to extra time. No further goals were scored, and the match went into penalty kicks. Misses by Julio César "Morocho" Anderson and Benjamín "Mincho" Monterroso allowed Independiente to prevail, 4-2, but Municipal had earned continental respect. 1980s: Almost relegated Municipal's glory years continued with another league title in 1976, but their results began to fade. They finished 8th in 1979-80, and in 1981 they fell even further to 11th, forcing them into a relegation mini-league. Ironically, their safety was secured when old rivals Tipografía Nacional were relegated instead. In 1982, the club came even closer to oblivion, finishing 9th in the regular season. That result put them back in the relegation mini-league, and this time they escaped only on goal differential. Over the next several years, Municipal put some distance between themselves and the bottom of the table, but they would not seriously challenge for
