If you imagined some kind of masked caped superhero chap leaping over tall buildings in a single bound - you're on the wrong track.This is about refs getting it right about whether a ball has crossed the goal line or not.The Premier League have asked Reading to test the Hawk-Eye goal-line technology during their youth team matches next season.A microchip in the ball will send an encrypted radio signal when it crosses the line.
Cameras positioned near the goal then relay the signal to a computer which sends a vibrating message to the referee's watch in a split second.So if it works okay refs will have more than one reason to look at their watches now..!
