www.bbc.co.uk/sport/football/62208661 I'm interested to now not only how this will change the game for u12 football (and remember there's a chance it may do further up ages levels and into open-age/Adult football in the future) AND how to referee this. If a player heads the ball, does a ref have to decide if deliberate and if not play on what if a goal is scored and if it is deliberate then what? Indirect FK to opponents? Corners wont be the same and you could presumably coach these are less of a big deal etc, would change the game significantly.
