The first games of the Cup brought a lot of doubts to the orange team due to having three points in three games, as a result of three ties as visitors against Universidad de Chile and the Peruvian teams of Atletico Torino and Sporting Cristal.

But Cobreloa did not loose control: with astonishing victories to the Peruvians (scorig 12 goals in two games) and a very complicated victory over Universidad de Chile, Cobreloa got the tickets to the semifinals. Cobreloa was unveiling as the Cup's revelation team.

In semifinals, Cobreloa had to face two of the best teams of the continent at the time: The Uruguayans Penarol and Nacional. Penarol had reached the phase by defeating Portuguesa and Estudiantes from Venezuela. Nacional, on its part, was just entering the tournament as the Cup's holding champion.

Many thought that Cobreloa would say goodbye to the Cup at this point, but Vicente Cantatore's men began to write one of the most succesful pages of Chilean football abroad: In less than a week, Cobreloa defeated both teams in the mythical Centenario Stadium of Montevideo, thus becoming the first chilean team to accomplish that. Paradoxically, the performance of the Uruguayan Washington "Trapo" Olivera were a key aspect to the visctories. Cobreloa thus, reached the final.

The final was against Flamengo (Brazil), which had eliminated Jorge Wilsterman (Bolivia) and Deportivo Cali (Colombia) in semifinals. Both teams had not lost a single game, so the final was promising. However, all the bets went to Flamengo, which had in its team players like Careca, Zico, and other players from the Brazilian National Team.

Cobreloa had to play the final in Santiago, because the CSF ruled that the Calama Municipal Stadium could not hold the final for not having a capacity of 30,000 people. Overcoming this, Cobreloa forced a third game: A tight loss in Brazil and a tight victory in Santiago were the results. The third game was held in Uruguay, where --for obvious reasons--, were almost as the home team. Eventually, Cobreloa lost to Flamengo 2 to 0, but maybe the history would be different if Cobreloa had played in Calama.
