How does a player signal for a substitution?

A player signals for a substitution by raising their arm and waiting for the referee's approval. This method is clearly defined in the rules of soccer to maintain order and ensure that the referee is aware of the intended change. The raised arm serves as a visual indication to the referee that the player is ready to be substituted, and this action helps prevent confusion during a game, particularly in a fast-paced environment where numerous actions are happening simultaneously.

By waiting for the referee’s approval, the player demonstrates respect for the game's regulations. The referee will then confirm that the substitution is allowed at an appropriate stoppage in play. This procedure emphasizes the structured nature of soccer, where communication and signals are crucial for smooth operation during matches.
