Electronic eye to end goal disputes (4th March 2007) From Ref. Mal
The Premier League has agreed to the introduction of goal-line sensors after being given approval by football's rule-makers. The system, which is being developed by the UK company Hawk-Eye, would give a definitive decision on whether the ball had crossed the line.
The move comes after referees' chief Keith Hackett and Premier League general secretary Mike Foster made a presentation to the International Football Association Board (IFAB) in Manchester yesterday. 'Hawk-Eye has a great reputation within tennis and cricket especially, and I would hope we could start trialling it within weeks at [a training] academy,' said Hackett.
However, Paul Hawkins, head of Hawk-Eye, told The Observer that it was unlikely the system would be fully operational for another two seasons. 'Getting a system to work is easy, getting it to always work is much more difficult. We have to make sure this works every time or it will lose credibility,' he said.
The decision to develop goal-line technology follows several recent controversies in which goals have been disallowed. Two seasons ago, a shot from Tottenham Hotspur's Pedro Mendes clearly crossed the line by a yard before being scooped away by Manchester United goalkeeper Roy Carroll. The match ended goalless.
This season a header by United's Nemanja Vidic clearly crossed the Portsmouth goal-line. Again no goal was given, though the match still ended in victory for United, 2-1.
During its meeting yesterday, the IFAB laid down four criteria for goal-line systems:
· The technology should only apply to goal-line decisions.
·The system must be 100 per cent accurate.
·The signal sent to the referee must be instantaneous.
· The signal is only communicated to the match officials.
The Hawk-Eye system uses a camera taking 600 frames a second on the goal-line. The information is analysed by computer and sent to the referee's headset or a device on his wrist. The equipment has been tested at Fulham's Craven Cottage ground but not on match days.
Other suppliers were given the go-ahead to continue experiments, including Adidas and German company Cairos, which has been struggling for two years to refine a system that uses a microchip inside the ball
