What is goal line technology?

Answer 1

Goal line technology is a technology that is being ivestigated to be used in football. It has come into the spotlight because of recent incidents where in games, the ball has crossed the line, but has not been noticed by the referee, and so the goal was not given. Sometimes when the ball crosses the line by a couple of inches before being hoofed out by a defender, it is difficult for the ref to see. Examples of this include:

• Roy Carrol famously carried the ball over the line after a 50 yard shot by Pedro Mendes in 2005, with the score at 0-0 between Manchester United and Tottenham - the goal would have given Tottenham the win
• Manchester United's Ryan Giggs slid the ball in in extra time of the 2007 FA Cup Final, where Chelsea's Petr Cech 'saved' the ball about a foot inside the goal line. The goal was not given and Chelsea went on to win the game. The goal would have seen Manchester United leading 1-0 with not much time left in the final
• perhaps the most famous of all is Geoff Hurst's goal in the 1966 World Cup Final, which clearly did not cross the line and led to England winning the World Cup

The technology involves embedding the football with a microchip, and having sensors on the goal line, so the when the ball passes the goal line, the microchip will send a signal to the referee and he knows its a goal
