UEFA's managing director of refereeing, Roberto Rosetti, has said: “Being a referee in the modern game is very difficult. The official in the middle takes between 200 to 250 decisions per match - that is one every 22 seconds - in difficult and sometimes controversial situations, under huge pressure, with each of them scrutinised and re-watched from multiple different angles by fans and pundits alike. They (referees) receive a lot of information from the Video Assistant Referee (VAR), and we are ready to speak and share more details with the players and coaches to help them understand how a decision was taken. Explaining a decision with up to 22 players mobbing you is impossible for a referee. It can lead to a breakdown in communication, with the beautiful game turning very ugly very quickly.
“We ask that all teams ensure their captain is the only player who speaks to the referee. We ask the captains to ensure their team mates do not encroach upon and surround the referee, allowing direct conversations to take place in order that the decision be relayed in a timely and respectful manner. Importantly, we want only the captain from the team who wishes to discuss a decision to be able to approach the referee.”
