Barreto: two consecutive World Cup finals as assistant referee

Uruguayan Ramon Barreto was the only referee in the history of FIFA to have been appointed to two consecutive World Cup finals: Germany – Netherlands, in Munich 1974, and Argentina – Netherlands, in Argentina 1978, both as assistant referee.
Barreto was selected for three World Cups, starting with Mexico 1970. Four years later, in Germany, he refereed the highly publicized match between East Germany and West Germany (1-0) in Hamburg and Poland – Sweden (1-0) in Stuttgart. He also assisted English referee Jack Taylor during the final between West Germany and the Netherlands (2-1). Barreto’s third World Cup was Argentina 1978, where he was appointed referee for Italy – Hungary (3-1) and the repeat of the 1974 final between West Germany and the Netherlands (2-2). He was then selected as assistant referee for the final game between Argentina and the Netherlands (3-1), with Sergio Gonella, the first Italian ever to referee the final. Ramon Barreto was also the referee of the 1976 Olympic Games final in Montreal between East Germany and Poland (3-1).
After his retirement, he became the chairman of Rampla Juniors, president of the Uruguayan Federation of Cycling and chairman of the Uruguayan Referees Committee.
Ramon Barreto recently suffered from an infection of a knee injury that, added to his diabetes, led to his death aged 76. "Ramon, what can I say? Just thank you! Deservedly, we talk about your remarkable career. You're the greatest!" wrote Jorge Larrionda, the last Uruguayan World Cup referee, on his Twitter account.
