1930 FIFA World Cup [SEP] Introduction
Only a few European teams chose to participate because of the difficulty of travelling to South America. The teams were divided into four groups, with the winner of each group progressing to the semi-finals. The first two World Cup matches took place simultaneously and were won by France and the United States, who defeated Mexico 4–1 and Belgium 3–0, respectively. Lucien Laurent of France scored the first goal in World Cup history, while that day United States goalkeeper Jimmy Douglas posted the first "clean sheet" in the tournament. Argentina, Uruguay, the United States and Yugoslavia each won their respective groups to qualify for the semi-finals.
