Reply to comment by YuriAddict7 in Polish referee Szymon Marciniak will take charge of the #FIFAWorldcup final by No_Arachnid6406

If I remember correctly the goal line technology sends a signal to the watch when a goal is scored. The mic is used for communication with the other officials including VAR. The goal line technology doesn’t need another official to tell the referee that goal line technology has detected a goal.
