According to "Rules of the International Football Association", the ball used in the match must conform to the rules of the association, and it must be inspected before the game to ensure that the standards such as size, weight, air pressure and material of the ball meet the requirements. Usually, before the start of the game, the referee will check the ball used for the game to determine whether it meets the requirements, and then draw lots to determine the ball rights, and check the players before the game officially begins.
In a football match, the match ball is provided by the organizer or the referee organization, and the referee decides which ball to use.
