It is a sad state of affairs that the fates of two teams are decided on a VAR decision that is inconclusive. The official purpose of VAR as stated by the Premier League on its website is…
In the Premier League, there will be a high bar for VAR intervention on subjective decisions.
The decision of the referee, known as the “Referee’s Call”, will stand unless, in the opinion of the VAR, based upon the evidence readily available, that call is a clear-and-obvious error.
If a clear-and-obvious error is identified by the VAR, for subjective decisions, after checking the up winnings attacking possession phase (APP) for any clear infringements by the attacking team, the VAR will advise the on-pitch referees to use the pitchside monitors (the Referee Review Area (RRA)) to review the incident and make a final decision.
This momentous VAR decision was not a clear and obvious error in my opinion.
