Goal-line technology

The Football Association will install a system at Wembley Stadium in time for August's Community Shield. Top-flight clubs voted to adopt the system during a meeting of the 20 Premier League chairmen on Thursday. Hawk-Eye is known for providing tennis and cricket with ball-tracking technology. Its football system notifies the referee if the ball has crossed the goal line via a vibration and optical signal sent to the officials' watches within one second.
