The Premier League in England will enter a new era in the 2013/14 season, when goal line technology will be used for the first time.

The Hawk-Eye system makes use of multiple cameras placed at each end of the pitch to ensure referees can be sure if the ball has crossed the line for a goal.

The BBC's Natalie Pirks went to the Emirates Stadium to find out more from referee Anthony Taylor.
