Association football, more commonly known as  football or soccer , ^[a]  is a  team sport played between two teams of 11  players each, who primarily use their feet to propel a  ball around a rectangular field called a  pitch. The objective of the game is to  score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed  goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world’s most popular sport.
