After years of debate the first goal line technology is to be brought in to English football.
Football officials showed off the new kit at the Emirates Stadium in London today - home, of course, to Arsenal Football Club.
The technology uses special cameras placed at several points on the pitch.
Referees will wear a specially designed watch that will receive a text message triggered by the cameras that will say whether it was a goal or not.
The Hawk-Eye system will come into play for the 2013/14 season of the Premier League in England.
