Two major incidents have basically been responsible for the sudden surge in demand for implementation of technology in the football field. The first was Englands Frank Lampard, whose goal could not be seen by the referee when it bounced off from the crossbar and crossed over the goal line. The second incident, happening hours later was a goal by Argentinas Carlos Tevez which was allowed because of the inability of the referee or his assistants to see that the goal was a shot from the offside. The second was the clear blunders by the referees on the field, which resulted in the demands of induction of technology in the playing field.
While in these two incidents the entire media and the rest of the spectators saw, with the help of numerous cameras across the stadium, that the decisions doled out at the moment was incorrect, the referees had to depend on their own eyesight to give their decisions. But these have not been the only two incidents in football history that have been seen as signs of referee shortcomings. For example during the Africa Cup, July 2010, victor ikpeba of Nigeria, whose penalty goal was denied even though television showed that the ball did croos the goal line, cost the Nigeria the trophy. This resulted in a national outrage against the match officials. There are many, from the fans to the players themselves who believe that such decisions have changed the course of the matches themselves. It is although impossible to say if the matches would have ended differently for the teams, but these stray incidents do cause doubts to rise. Thus, there has been a major demand from various sections of the football world to introduce technological aids in matches to help the referee and his assistants make sound and confident decisions.
But FIFA refused to relent and believed that the game had to remain unchanged to maintain the fascination for the game. One of its many pointless arguments was that this technology was expensive, and thus it would become unfeasible to many poorer teams and associations. Many advocates for the new technology believe that international football has grown too much and become too valuable to let such discrepancies happen. Thus implementation is only sought for international matches. After reeling under a lot criticism, FIFA is presently ready to review new goal line technologies and has declared 2010 to be the last world cup under the present rules. It has already begun reviewing popular technologies.
One is the hawk eye technology already used in many sports such as snooker, cricket and tennis. This technology uses a number of cameras placed around the stadium to calculate the 3-D position of the ball in the stadium. Another is the Cairos GLT system jointly developed by Adidas and Cairos technologies AG. This consists of implanting sensors in the ball and using magnetic fields in the goal post, detecting whether the ball has crossed the goal line or not. It seems that FIFA has finally realized its folly and learned to move with the times.
