Known as the most popular sport in the world, football is played by two teams of eleven players on a circular field. The players kick the ball toward the opponent’s goal and try to score a goal by kicking the ball into the net. The game is governed internationally by the Federation Internationale de Football Association (FIFA), a global authority which regulates the activities of agents. All agents must be licensed and pass written examinations conducted by national associations.
Generally, a football game is played in two 45-minute periods. The teams are allowed to make three substitutions. During the season, most countries operate cup competitions. The winners are eliminated from the cup competitions, while the losers continue to play in the regular season.
Each team has its own playbook, consisting of dozens or hundreds of plays. These plays are strategic and must be played in the best manner. The players must understand their role in the game. They must also value their teammates’ efforts.
The players are required to wear protective gear. Their hands and feet must be covered with shin pads and boots. They must also avoid contact with the ball.
The ball must be circular. It must be 58 to 61 cm in diameter. The team’s goalkeeper will defend the goal. The players pass the ball between their legs and to teammates. They may also attempt to kick it into the goal.
In some countries, the lower divisions include amateur players. The top divisions usually feature highly paid star players.
