Unpacking nine VAR checks in chaotic half of football
Jamie Carragher called it "box office", commentator Peter Drury said it was "carnage and chaos".
After a weekend of more managerial ranting about video assistant referees (VAR), referee Michael Oliver and his PGMOL boss Howard Webb were probably hoping for a quiet London derby.
No chance…
In 45 minutes - with an extra 12 minutes added on - there were countless VAR interventions in Tottenham's match with Chelsea, including four disallowed goals, three red card checks and a penalty.
The second half had more goals, albeit slightly less mayhem as Nicolas Jackson ended up scoring a hat-trick in Chelsea's 4-1 win.
Mercifully, defeated Spurs manager Ange Postecoglou was measured with his post-match verdict, saying: "That utopia where there are no wrong decisions in the game will never exist. It's our own fault as we complain about decisions every week."
Here BBC Sport recaps all the major incidents, on yet another busy night for Premier League's scrutinised officials…
14 mins - Spurs goal disallowedTottenham's Brennan Johnson uses his pace to get away down the left and he plays a perfect ball for Son Heung-min to tap in, but the flag is up for offside, with VAR confirming the tight offside decision.
Ex-Chelsea goalkeeper Mark Schwarzer on BBC Radio 5 Live said: "Very, very close. Another really good move from Tottenham down this left-hand side. I said it before, but Chelsea look really shaky at the back."
'One of the most mind-boggling Premier League games ever'Son Heung-min thought he had doubled Tottenham's lead, but it was ruled offside, following a VAR review18 mins - potential red card for UdogieDestiny Udogie makes a really risky challenge as he dives in two-footed, off the floor on Raheem Sterling. He is booked but VAR has a look and the yellow card remains, controversially.
Schwarzer said: "If it is 10 or 15 centimetres to the left, I think that's a red card."
But ex-England defender Gary Neville on Sky Sports said: "Destiny Udogie should have been sent off. You don't have to break a player's leg to get a red card."
22 mins - Chelsea goal disallowed for handballReece James plays a brilliant ball out wide to Sterling, who goes into the box, a first shot deflects onto his arm off Pedro Porro but he keeps going and then manages to force the ball into the net. But Chelsea's celebrations are cut short with VAR ruling the goal out for handball.
Schwarzer said: "Great persistence there, Sterling just keeps going. He picks it up wide on the left side and goes through one challenge and scores. But that is handball."
22 mins - Romero kicks out at ColwillIn the build-up to that disallowed goal, Cristian Romero kicked the leg of Levi Colwill off the ball. A VAR check comes and goes and Romero stays on the pitch...for now.
Ex-Chelsea striker Chris Sutton on BBC Radio 5 Live said: "I'm glad I saw it again because when I first saw it I thought Romero definitely lashed out but then it was just a meek kick."
Neville said in commentary on Sky that he was "50-50" having watched the incident again on a replay.
28 mins - Chelsea have another goal disallowedMoises Caicedo drives a shot in from outside the box but the effort goes through the legs of Nicolas Jackson and the flag is up. After a VAR check, Jackson is narrowly ruled offside and the decision stands.
Schwarzer says: "Jackson in the line of the goalkeeper is the only thing it can be because no-one else is offside."
Nicolas Jackson was adjudged to be offside, ruling out a Chelsea goal for the second time in the match.28 mins - Chelsea get a penalty, Romero sent offBut... earlier in the same move, Enzo Fernandez was left on the floor in the penalty area and now we see why. Romero, lucky to have stayed on the pitch earlier on, challenges Fernandez, but then catches the Chelsea man on his follow-through on his ankle.
The on-pitch referee is urged by the VAR official to check the incident on the pitch-side monitor. The referee then awards a penalty and shows Romero a straight red card for dangerous play. The incident is then replayed on the big screens at the stadium with the Spurs fans booing the decision as they think Romero got the ball first.
Cristian Romero became the first Tottenham player to be sent off in the Premier League this seasonEx-Liverpool defender Jamie Carragher on Sky said: "Absolutely ridiculous to put in a challenge like that in the box. Those days are long gone when you say 'I got the ball first'. He was out of control, excessive force, definite red card."
Neville added: "I have no sympathy for him. It's the wildest of challenges."
Cole Palmer converts the penalty, with his spot-kick going in off the post after Guglielmo Vicario got two hands to it.
37 mins - Chelsea have another goal disallowedJackson has the ball in the net, converting from Sterling's cross but this is an easy decision with the England man clearly offside when receiving the ball.
43 mins - Postecoglou bookedChelsea's victory brought Ange Postecoglou's unbeaten start at Tottenham to an endFeisty on the pitch and in the technical areas. Spurs boss Ange Postecoglou talks himself into a booking.
Schwarzer said: "You don't see Ange lose his cool too often. He wasn't over the top. He probably just gave the fourth official a bit of an earful."
45+7 mins - Sterling goes down, no penaltySterling is challenged by Pedro . No penalty awarded and Sterling went to ground easily and is lucky to have not been booked for diving.
Sutton said: "We saw at the weekend [Sheffield United's] George Baldock diving. While there is rage at the referees and their level of performance, every week we see players cheating and diving. Yet we don't hear managers calling out players for that. They will congratulate players for winning penalties."
45+8 mins - Colwill and Matar Sarr booked for pushing and shovingChelsea's Levi Colwill was substituted at half-time, after picking up a booking for his spat with Tottenham's Pape Matar SarrChelsea's Levi Colwill and Tottenham's Pape Matar Sarr are involved in some pushing and shoving. Both get a booking with no need for further punishment.
Schwarzer, accurately predicted: "I would be very surprised [if this stayed 11 v 10]. Chelsea having the man advantage and haven't made use of that yet.
"Colwill there should be thinking, 'we've got the man advantage' so just walk away. What is Colwill doing? Why is he even involved? Just walk away."
45+11 mins - No action taken against James for flailing armA clash between Reece James and Udogie. It is a check for a possible red card, with James catching Udogie with a flailing arm, but no action taken.
Second halfThere were fewer incidents in the second half but still some (not to mention Nicolas Jackson's hat-trick)
55 mins - Udogie becomes second Spurs man to be sent offDestiny Udogie, 20, has started 10 of Tottenham's 11 Premier League matches this season.Udogie, who could have been sent off in the first half when he started the chaos with his two-footed lunge, now does see red for his second booking.
It is a late, mistimed sliding challenge on Sterling and Spurs go down to nine.
Neville said: "I can't believe the madness. He knows he is on a booking and Sterling is going away from goal."
Schwartzer added: "As soon as he makes the challenge and he gets it wrong, he knows he is going to go.
"I think it is just a rush of blood and he must feel he is going to get to it but Sterling is very fast. As soon as he makes it, he knows he is going to go."
75 mins - Chelsea take the leadJackson steers in Sterling's cross. A VAR check to see if Sterling was onside, he was, goal stands.
"My first initial thought was that Sterling was offside. The linesman kept his flag down," said Schwartzer. "But he is onside. My vision is not as good as it used to be!"
79 mins - Tottenham's potential equaliser disallowed for offsideEric Dier's strike was the fifth disallowed goal in the match between Tottenham and ChelseaEric Dier thinks he has made it 2-2, volleying in at the back post. The flag is raised, but another lengthy VAR check follows - which keeps the decision as no goal. The fifth disallowed goal of the game.
Schwarzer said: "It depends who it has come off. But what a finish from Eric Dier. What a finish. I think [Rodrigo] Bentancur gets the first header but it looks like initially [it could] have come off a Chelsea player first. This is an easy [decision] compared to what we've had tonight."
And Chelsea took advantage with Jackson netting two more to seal a hat-trick.
