The Premier League is to introduce a multi-ball system for the forthcoming season with 10 match balls in use at each top-flight game in an attempt to speed up play and cut down on time-wasting.
One ball will be in play, one with the fourth official and eight will be placed at various points around the pitch on cones. Two will be behind each goal and two along each touchline. Those behind the goal must be positioned such that they do not interfere with the Hawk-Eye goal decision system.
Clubs have been told to use a minimum of eight ball assistants who must make eye contact with the player restarting play before throwing them the ball, and must give the ball at the same speed to both clubs.
