Video Assistant Referee causes controversy every week in the Premier League, but how are decisions made, and are they correct?
After each weekend we take a look at the major incidents to examine and explain the process both in terms of VAR protocol and the Laws of the Game.
In this week's VAR Review: Why Liverpool's penalty at AFC Bournemouth was allowed to stand, why Aston Villa's "equalizer" at Wolves was ruled out for offside, and comparing a possible penalty for Brighton to another conceded by Arsenal's William Saliba.
Bournemouth 0-2 Liverpool
Possible penalty overturn: Foul by Cook on Gakpo
What happened: Andrew Robertson played a ball through the center for Cody Gakpo to run on to in the 27th minute. As the Liverpool forward got into the area, he went down and appealed for a penalty after contact by Lewis Cook. Referee Darren England pointed to the spot and it was checked by the VAR, John Brooks.
VAR decision: Penalty stands, scored by Mohamed Salah.
