Arsenal and Tottenham fans are usually the best of enemies but joined forces to vent their frustrations at the decision.
Arsenal fan @antenehaf posted on X: "They don't know what they are doing. You can't pull it back for that and re referee the game. It is a mutal tussle. We all hate spurs but deciding a game on that is an absolute joke."
And @TalkoftheSpurs·9h added: "He's not looking at the ball because Burn has Bentancur's head jammed in his armpit! Game has gone! Absolutely mental!"
Arsenal fan @marissacthomas4 seethed: "As an Arsenal fan, I'm always amused when Tottenham concede but that penalty decision was ridiculous. I would be fuming if that was given against my team. No matter who you support, the lack of consistency is infuriating.
And another Gooner @kimmoFC posted on X: "Another howler from VAR. You can't give this as a penalty. Even Burn is surprised."

Tottenham manager Thomas Frank was also furious with the decision to award Newcastle a penalty. He told BBC Sport after the game: "It was an absolute mistake from the VAR. The referee did good to do the ref call and they encourage the refereeing call on the pitch. For me, that is never a penalty. Even speaking to some from Newcastle [they] don't think it's a penalty and we need consistency. I think the referee's call on the pitch, he nailed it, and VAR can only be if it's clear and obvious."
Perhaps unsurprisingly, Newcastle boss Eddie Howe disagreed with Frank. He explained: "I hadn't seen it, I'm only seeing it now. The big thing is the defender isn't looking at the ball at all, he's looking at Dan [Burn]. I think it's probably the right call."
