The Hawk-Eye system sees where the ball goes (on a static basis)

VAR in football
- 1. Doubts assignment of a penalty;
- 2. Validation of a goal;
- 3. Attribution of direct red cards;
- 4. Exchange of identity between players during admonition or expulsion.
In this case, It is not technology that gives the indication that can confirm or deny the decision of the referee, but it supports the VAR and its assistant video assistant referee (AVAR) for their interpretation. They are in radio communication with the referee, watch the video images and explain to the match director what happened.
