A Jamie Vardy hat-trick coupled with goals from James Maddison and Youri Tielemans steered Leicester City to a stunning 5-2 win at Manchester City and kept them top of the Premier League with a maximum nine points from three games.
City had not conceded five goals in a home game since February 2003 against Arsenal and it was the first time their boss Pep Guardiola had seen a side he is managing concede five in what was his 686th game in the dugout.
"They didn't want to play, they defended so deep and just wanted to counter-attack," Guardiola told the BBC.
"They scored the first time they arrived and had three penalties in total, so it was very difficult for us. The lack of creating chances made us nervous and anxious."
With injured strikers Gabriel Jesus and Sergio Aguero unavailable, City lacked bite as Raheem Sterling looked uncomfortable on his own up front while a porous defence was unable to contain Leicester's lethal fast breaks.
The defeat snapped City's 11-match unbeaten home run in the league dating back to last season, while it was also their first defeat in an opening top-flight home game since a 2-1 loss to Southampton in 1989.
Meanwhile, Newcastle United manager Steve Bruce described the new interpretation of the handball law in the Premier League as "nonsense" despite benefiting from the latest controversial decision.
Newcastle were given a stoppage-time penalty after the referee, using the VAR monitor, ruled that Eric Dier had handled the ball as he jumped up for an aerial challenge with Newcastle's Andy Carroll.
Dier had his back to the ball and the header hit his outstretched arm at close-range but referee Peter Bankes awarded the penalty which was converted to give Bruce's team a 1-1 draw.
In practice, the new interpretation of the law, which allows less leeway for cases where the ball strikes an arm or hand, is resulting in more offences being given for what would once have been viewed as accidental handball.
On Sunday, Crystal Palace lost to Everton after a penalty was awarded for a handball against Joel Ward and Manchester United won their game at Brighton 3-2 thanks to a handball penalty awarded by VAR after the final whistle.
Palace's former England manager Roy Hodgson was scathing in his comments after the Ward incident, describing the rule as a nonsense and saying it was ruining the game.
Bruce agreed with Hodgson's assessment.
"I can understand why Spurs will go berserk and Roy Hodgson reacted like he did. It is a total nonsense, we should be jumping through hoops but I would be devastated if that was us.
"Maybe Roy is right, maybe we all need to get together. The decisions are ruining the spectacle.
"I thought VAR was coming in for clear and obvious decisions. It ruins, for me, the spectacle of the Premier League.
"I should be delighted but I know it will bite me eventually. All we seem to be talking about is VAR."
Other results saw Leeds United beat Yorkshire rivals 1-0, while West Ham United secured their first points of the Premier League season with a 4-0 home win over Wolverhampton Wanderers, a result that will have boosted the spirits of manager David Moyes who missed the game after contracting COVID-19.
