The VAR can intervene in one of the following instances:
- A clear and obvious error by the on-field match officials relating to goalkeeper movement
- A double touch by the penalty-taker
- Feigning at the point of the kick by the taker
- Encroachment by players that has a direct impact on the outcome of the kick
The 2020/21 protocol does not allow for tolerance levels, so if the goalkeeper saves a penalty and his foot is over the goalline then VAR will advise it is retaken.
If the goalkeeper is off his line and the ball hits the post or goes over, it won’t be retaken unless the 'keeper has a material impact on the kick being missed.
For player encroachment in the box, it is now judged on any part of a player’s body that is on the ground when the kick is taken.
Therefore, if any part of the foot is on the penalty area or arc line it is encroachment. The player must still have a material impact on the outcome of the kick.
