Various technologies have already been approved for use in football matches around the world, with some being limited to elite leagues or international football competitions, because of the cost implications. However, many federations and competition organisers have attested to the need and importance of investing in technology in sports, especially football, for better game management and for reducing instances of perceived favouritism during matches. Betting has also undoubtedly incorporated the use of technology. It is now possible for people to place bets through online casino platforms, and use advanced software to check, for example, team statistics, before placing bets, among other information.
Goal-line technology is a goal decision system which uses electronic devices. It determines if a goal has gone in or not. In other words, if the ball has crossed the crossbar or goal-line during a football match. The main aim of goal-line technology is not to replace the role of the centre referees, but to help them make an informed decision when awarding or rejecting a goal appeal from the players. Previously, it was possible for the referee to either award or deny a goal, but after viewing the replays, it’s seen that a wrong decision was made.
Goal-line technology received the full backing of the International Football Association Board back in July 2012. Since then, leagues have been allowed to make use of the technology, although it’s not a requirement during football matches. However, the technology has been used in major European domestic competitions, and international competitions, such as the World Cup in 2014 and 2018. With the cost implications associated with goal-line technology, only a few clubs in the world have been able to install the system. Currently, only 174 stadiums appear on the FIFA website as having goal-line technology as of March 2019.
