This scene is still a big topic of conversation. Was the ball in the goal, or was it not? In the second Bundesliga, there is no technique that could prove this as in the first Bundesliga. Maybe the ball were milimeters on the goal line and this is no goal for darmstadt. They  make the 1-1 later, if they had lost, that wouldnt fair.
