The VAR was once again a source of controversy after an unusual decision that after a penalty was annulled by Chelsea.
The Blues received a penalty during the first half of their clash in Brighton when Facundo Buonanotte was convicted for having committed a foul against Marc Cucurella.
However, replays showed Buonanotte won the ball in what was a timely challenge, and VAR called referee Michael Salisbury to review it.
Salisbury went to the monitor and disallowed the penalty, but for some reason called for a drop ball instead of a Chelsea corner.
And on a day when it was revealed that Premier League clubs will vote potentially ruling out VARArbitration became controversial again.
Many fans on social media were confused by the result, with one from X saying: “Good decision, not a penalty but it should have been a corner for Chelsea.”
“So if it's not a penalty, how the fuck is it not a corner? Even when VAR works 'properly', they still manage to make a mistake, throw it away,” added a second.
A third said: “I don't understand how referees work sometimes in this Premier League. If it's not a penalty for Chelsea then it's a corner for them. It's clear as day.”
“Sorry. No pen. No corner. No ball for Chelsea. Wow,” added a fourth.
Fortunately for Chelsea, they took the lead just after the half-hour mark when Cole Palmer cleverly headed in Cucurella's cross from the left.
The Blues had to substitute with a concussion in the 42nd minute after Mykhailo Mudryk collided with Tariq Lamptey.
Christopher Nkunku replaced him moments before Nicolas Jackson thought he had headed the second, but he was ruled offside.
Nkunku doubled Chelsea's lead after the hour mark with a fine finish from a Malo Gusto cross.
However, the Blues were reduced to ten men in the dying minutes of the game after Reece James kicked Joao Pedro.
Brighton set up a tense final few minutes of added time when substitute Danny Welbeck scored from close range, but it only turned out to be a consolation goal in a 2-1 win for Chelsea.
