Algeria caused one of the great World Cup upsets on the first day of the tournament with a 2–1 victory over the reigning European champions, West Germany. In the final match in the group between West Germany, Austria and Chile, with Algeria having already played their final group game the day before, the European teams knew that a West German win by 1 or 2 goals would qualify them both, while a larger West German victory would qualify Algeria over Austria, and a draw or an Austrian win would eliminate the West Germans. After 10 minutes of all-out attack, West Germany scored through a goal by Horst Hrubesch. After the goal was scored, the two teams kicked the ball around aimlessly for the rest of the match. Chants of "Fuera, fuera" ("Out, out") were screamed by the Spanish crowd, while angry Algerian supporters waved banknotes at the players. This performance was widely deplored, even by the West German and Austrian fans. Algeria protested to FIFA, who ruled that the result be allowed to stand; FIFA introduced a revised qualification system at subsequent World Cups in which the final two games in each group were played simultaneously.
