Every 4 years, billions of spectators watch how their national teams take part in the football world cup. This is the moment that all football teams are looking forward to. In fact, the FIFA World Cup is probably the most important sporting event in the world.
The World Cup was created in the 1930s, when Jules Roumet, a French football official, came up with the idea of putting the best football teams in the world together in a game against each other for the title of world champions. Huge enthusiasm arose over his idea, and the first FIFA World Cup was organized in Uruguay in 1930. The home team won the first world cup when it defeated Argentina 4-2. Since then, nearly 20 world tournaments have been played, and competitions have often surprised fans around the world. Everyone was surprised when the USA beat England with a 1-0 score in the 1950m. The 1966 World Cup struck many fans when Italy lost 1–0 to North Korea, and Northern Ireland caught everyone by surprise when they beat the Spanish home team 1-0 in 1982.Many legends and many football records were made during the World Cups. Irishman, 17-year-old Norman Whiteside was the youngest player ever to fight for the World Cup, and Pele was the youngest who scored a goal and won the World Cup. Ronaldo scored the largest number of goals in the history of the fight for the World Cup, 15 goals.
Football history is built every 4 years during the FIFA World Cup. Whatever the result, the championship brings together people from all over the world in the spirit of fun and sport.
