Penalty in football has a strange history. You might think this was the way it was in penalty shootout from the beginning, but in the 90s, there was a certain type of penalty in the football world that used to throw the ball through the middle and move towards the goal. And the goalkeeper was also allowed to come forward. The rule in this model of penalty was that the ball should not move in the width and always had to move in the longitudinal direction.
