From next season on we're going to see an interesting change to the way free kicks are taken. The IFAB has approved a rule change which prohibits attacking players - ie those from the team on attacking from the free kick - from being in the wall. Specifically, when there is a wall of three or more players attackers are not allowed within one metre of it. Any attacking player found to be less than one metre from the wall when a free kick is taken will be penalised and the other team will be rewarded with an indirect free kick.
