Football, also known as soccer, is a sport played between two teams of eleven players, using a spherical ball. The objective of the game is to score goals by getting the ball into the opponent's goal.
The modern game of football was developed in England during the 19th century, but the origins of the sport can be traced back to ancient civilizations such as Greece, Rome, and China.
Football is played on a rectangular field with a goal at each end. The game starts with a kick-off, where one team kicks the ball to the other team. Players use their feet to control and pass the ball, and the team with the most goals at the end of the game wins.
The basic rules of football are: players cannot touch the ball with their hands or arms (except for the goalkeeper), players cannot foul or trip other players, and the ball cannot go out of bounds. There are also rules for offside, penalties, and substitutions.
Football is the most popular sport in the world, with an estimated 4 billion fans. It is also the most-watched and most-played sport, with professional leagues and tournaments in many countries. The FIFA World Cup, held every four years, is the largest and most prestigious international football tournament.
