The final day of the group stage in the 1982 World Cup in Spain saw the opportunity to advance out of Group 2 up for grabs. Algeria, playing in its first World Cup, had defeated Chile the day before to claim a 2-1-0 record. The Chileans were eliminated, but the West Germans (1-1-0) and Austrians (2-0-0) were still alive — and, crucially, playing each other. The facts were these: A draw or an Austrian win would send Austria and Algeria on, a German win by three or more goals would send West Germany and Algeria on, and a German win by one or two goals would send both teams playing on through. Unfortunately for the Algerians, that is exactly what happened. After a goal by West Germany’s Horst Hrubesch early in the first half, both teams seemed content to accept 1-0 as a mutually-beneficial final score. They lazily passed the ball around themselves for the remainder of the game, neither team making another serious attempt on goal.
