GLT buzz at half-time

The goal-line technology (Hawk-Eye) system recently worked better than expected in Netherland's First Division. Referee Danny Makkelie went crazy because of this new technology, which was used for the first time during a match in the Dutch top league last weekend. 
The reason: nobody had thought about the youth players from the home team, Utrecht, who were playing and trying to score during the half-time interval. According to AD Sportwereld, every time the ball crossed the goal line, Makkelie’s watch buzzed and the text “goal” was shown. The goal-line technology system is being turned on two hours before the match to test it. Since this was the first time the system was used in Netherlands, the technicians did not dare to turn it off because they were not sure if they could turn it back on.
