Marques was a known anti-communist and it is said he helped Chile in this match against the Soviet Union and help they needed.
Chile had just suffered a military coup by which right wing (to say the least) dictator Pinochet had ousted the left wing socialist elected leader Allende. (notice the typical 70s terminology). The Soviet Union had been a friend of Allende and needless to say Pinochet was a darling of the United States. In this cold war situation the Chilean National team arrived in a freezing Moscow for the first leg of the Play offs for the 1974 World Cup.
The Chileans were afraid. Afraid of the Soviets, who held two of them at the airport for hours (something with a passport photo), and afraid of the leaders back home who told them to win or else. This was a prestigious match.
Luckily for the Chilean team the Brazilian referee helped them to a draw. The return match would be much easier.
The return match was never played. The Soviets refused to play when it became known the match was going to be held in the National stadium. The very place where thousands of people had been held prisoner and had been tortured. In fact there were still prisoners in the stadium when FIFA officials came to take a look. There were also still visible traces of torture in the dressing rooms. And why doesn't this surprise us: the FIFA people ignored all that.
The Chilean team did show up for the second leg, if only to claim victory by default, but to please the audience the Brazilian team Santos was asked to stand in for a friendly. Santos beat Chile 5-0. The referee was Rafael Hormazabal.
