Football's lawmakers have been urged to broadcast referee conversations during games to stop incidents like Jurgen Klopp screaming at the fourth official.
Martin Cassidy, CEO of referee charity Ref Support UK, believes allowing fans to hear what is said on the field would 'change football overnight' and end abuse of officials.
Liverpool manager Klopp pulled his hamstring as he ran towards fourth official John Brooks to celebrate the late winner against Tottenham last week and was charged by the FA for accusing referee Paul Tierney of having something against his team.
