Football is the author's favorite sport. It is a team sport played between two teams who compete to score goals against each other. The game is played on a rectangular grass field with goals at each end, and teams aim to score more goals than their opponent. Players use their feet, legs, chest and head to pass and shoot the ball, but cannot use their hands besides the goalkeeper. A game is won by the team that scores the most goals by the end of play, and ties may be settled with overtime periods or penalty kicks. The World Cup is the most important international football competition.
