Goal or no goal? Maximum clarity concerning the most important issue in football has prevailed in the Bundesliga since the 2015/16 season. This was ensured by the introduction of goal-line technology from UK provider Hawk-Eye – technical progress on which the 18 Bundesliga clubs voted (15 for and three against) at the general meeting of the League Association on 4 December 2014.
The Hawk-Eye software uses the camera images generated to capture the exact position of the ball, even in situations where the game situation is confusing for the referee or because of adverse weather conditions. If for example, a second ball enters the pitch, operators inform the system which of the two is the correct one.
The system sends a signal to the referee in less than one second, if it recognises that a goal has been scored. A special watch is the key; it vibrates and displays the impartial message: Goal! In such a case, spectators and TV viewers are also informed – through TV recordings and video wall displays in the stadium that show the ball has completely crossed the goal line.
The Hawk-Eye system has been used already in the game of tennis since 2006, as well as in the Olympics and in the English Premier League since the 2013/14 season. Since the 2015/16 season, all 18 Bundesliga stadiums have been fitted with 14 cameras each, including two high-speed cameras at goal-line level. Hawk-Eye celebrated its debut in German football at the DFB Cup final between Borussia Dortmund and VfL Wolfsburg at the Berlin Olympic Stadium on 30 May 2015. The system was called upon to deliver judgement for the first time in the Bundesliga straight after the first match of the 2015/16 season, between SV Darmstadt 98 and Hannover 96. However, no goal was scored that time round. Goal-line technology is also used for all Bundesliga club home games in the DFB Cup, in the DFB Cup final, in the Supercup and in the relegation/promotion games of the 16th placed Bundesliga club with the third-placed Bundesliga 2 club, as well as in the match played between the 16th placed Bundesliga 2 club and the third-placed Liga 3 club.
