FIFA confirmed that the Under-20 World Cup that begins this Saturday with three games, will also be a great test of another step forward in the technology applied to football. It is about communicating the decisions that the main referee makes after a VAR review through a microphone linked to the stadium speakers.
What will not be heard publicly are the conversations that happen between the head judge and the VAR and AVAR judges. This same innovation had already been tested for the first time at the last Club World Cup in Morocco.
