Goal line technology has been officially introduced in the 2014 World Cup and 2013 Confederations Cup, both taking place in Brazil.
The two different methods, named GoalRef and HawkEye are the result of many questionable decisions made by match officials and pressure coming from fans, managers and football governing bodies. GoalRef works by detecting the ball passing in between the two goal posts with magnetic induction. We can be assured that the ball has crossed the line when we are informed of a change in the magnetic field. The second method, known as HawkEye, is known to be used in other sports such as tennis.
It works by visually tracking the trajectory of the ball with several high-speed cameras found at different locations and angles around the pitch and then proceeds to produce a record of the most statistically likely path of the ball. Both of these methods are considered very reliable and it is indeed very likely that one will be selected to permanently determine whether or not controversial goals will be given or denied.
The advantage of both of these methods is their reliability. With the use of these technologies, important decisions can be made in an unbiased manner, with no possible contradiction coming from either side. Everyone will remember the goal denied to Frank Lampard in the 2010 World Cup, which could have affected the final outcome of the game.
In my opinion, there is one inconsistency with the use of goal line technology. I do not believe this technology to be as useful in football as a simple instant replay, which would be useful in many more scenarios. This instant replay method would be used to determine penalties or fouls in the final thirds of the pitch, as well as providing the same help as goal line technology.
If certain people do believe that involving technology too much in football will slow the pace of the game, then why not give a limited number of replays for each team. If the manager of a team wrongfully demands an instant replay on two occasions in one half, then let that team lose the privilege to demand another for the rest of that half.
In conclusion, the introduction of goal line technology in football could be considered a step forward towards modernising the game, however, I believe that it is insufficient as it will only be used on two or three occasions in a season.
A cheaper and more useful method could be found in the instant replay. On the bright side, there will no longer be anymore controversially given or denied goals in the future of football. Perhaps in a few years, a more advanced, sophisticated and equally reliable technology will be used, without replacing the referee.
