Does a coach have the right to change the goalkeeper during a penalty kick?

A coach does have the right to change the goalkeeper during a penalty kick. The Laws of the Game, specifically Law 14 regarding penalty kicks, do not prohibit a team from substituting players, including the goalkeeper, at this moment. It’s an accepted practice that if a coach wants to substitute the goalkeeper for a penalty kick, they can do so just before the kick is taken, provided the substitution is completed before the penalty is actually executed.

While there may be tactical considerations that influence a coach's decision, and the referee must be informed and approve any substitution, the fundamental rule allows for this action. As such, the assertion that a coach is allowed to change the goalkeeper when facing a penalty kick aligns perfectly with the established rules of play.
