The maximum number of substitutions allowed in soccer is generally three, though this has changed temporarily in various competitions due to circumstances such as the pandemic. The ability to make substitutions allows teams to manage player fatigue, tactical shifts, and injuries during a match. Coaches strategically decide when to bring in substitutes to alter gameplay dynamics or provide fresh legs. However, specific tournaments may have different rules regarding substitutions, particularly in knockout stages, where additional substitutions or extra time may be permitted.
