What is the appropriate restart after a defender takes a throw-in that inadvertently deflects into the goal off the goalkeeper?

After a defender's throw-in inadvertently deflects off the goalkeeper and enters the goal, the appropriate restart is a kick-off. This is because the ball did not go directly into the goal from the throw-in; rather, it was played into the goal as a result of a deflection. According to the Laws of the Game, a goal only counts if the ball is deliberately played into the goal by an attacking player, so this situation leads to a kick-off to restart play from the center of the field after the goal has not been validly scored.

In contrast, a goal kick, penalty kick, or free kick would not be the correct restart method in this scenario, as those restarts apply to different game situations, like a ball that goes out of play, a foul, or an attacker's infringement. Hence, the kick-off effectively resumes the game after the situation described.
