Who should organise the wall at a free kick?

Keep the responsibility split very simple. The goalkeeper sets the wall because they can see the goal and the angle. One defender helps move the wall to the correct position. Another player stays alert to the ball, the quick restart and any short option. The remaining defenders organise the most dangerous runners and spaces. The important detail is that the whole team cannot turn away from the ball while the wall is being built. Agree the language in training so the goalkeeper does not need a long conversation during the match. If the referee is managing the distance or disciplinary action, the team must wait for the signal. If the restart is available quickly, the alert defender helps the group react. At U12, three clear jobs are enough: goalkeeper sets, one player helps, one watches the restart. The alert player protects against exactly that. Until the referee clearly makes the free kick ceremonial, assume a quick restart is possible. One player watches the ball, while the goalkeeper and helper organise the wall. If the whistle is required, the referee will signal when play can restart.
