1. A Wimbledon-Style 'Hawk Eye'
There have been various moments of contention in football down the years, many of which have become the topic of pub conversation, such as "did Geoff Hurst's shot cross the line at the 1966 World Cup?" Fortunately, we now have goal-line technology to help us clear similar grey areas up in the future - though this new video technology isn't as complete as the form used at Wimbledon and in tennis. With current goal line technology used in association football, only the referee is able to know if the ball has crossed the line or not, while some have called for contentious moments
to be depicted on a giant screen at football grounds, like in tennis matches. Arsenal manager Arsene Wenger even suggested managers
should have access to tennis-style 'challenges' to assess moments of controversy, both of which surely cross a line, if you'll pardon the pun. Football is about intensity, the heat of the moment and split-second decisions - that's what makes the beautiful game so unpredictable, and enjoyable. If you were to stop play for a few minutes to assess a moment of contention, football
would lose its ebb and flow.
