During that period, the greatest disappointment was at continental level with the team only reaching the group stage in the [[1988 Copa Libertadores]]. On 30 September 1989, the Estadio Monumental was re-inaugurated with an exhibition match against [[CA Peñarol|Peñarol]], which Colo-Colo won 2–1<ref name="ianu"/> with goals by [[Marcelo Barticciotto]] and [[Leonel Herrera Silva|Leonel Herrera]], the son of a legendary 1970s former defender of the same name.
