VAR has been under intense scrutiny since its introduction to the English top-flight this season, with some fans and pundits calling for it to be reviewed or scrapped until it can be improved.
According to a review, Premier League VAR officials incorrectly overturned four big decisions in recent weeks, with referees chief Mike Riley describing the outcome as "the worst".
One of the incidents involved Liverpool's Trent Alexander-Arnold, who was not awarded a penalty for a handball against Manchester City before the international break, despite Reds midfielder Fabinho scoring at the other end seconds later.
"The worst outcome is when the referee on the field makes the right decision and the VAR intervenes to make a wrong decision," said Riley, the former Premier League official who now heads up the Professional Game Match Officials Board.
Additionally, the VAR was wrong to disallow Sokratis Papastathopoulos' late goal for Arsenal against Crystal Palace last month, with the match finishing in a 2-2 draw amid controversy surrounding Granit Xhaka.
Other incidents included Brighton being awarded a penalty against Everton last month when Michael Keane stepped on Aaron Connolly's foot, and Manchester United's Daniel James being awarded a penalty at Norwich despite the on-field official's initial decision not to point to the spot.
Despite the problems, Riley is pleading with fans to give the system more of a chance, saying "Let's take all these learnings and go how do we improve the system going forward because we've all got a stake in making sure that happens."
