For the second time in a row, Leicester City overcame a terrible Tottenham team to triumph after falling behind.
Rodrigo Bentancur's deflection of Victor Kristiansen's sliced finish gave Spurs, with manager Antonio Conte back in charge after having his gallbladder removed, the perfect start.
The game, however, was turned around when the resurgent Foxes scored twice in less than two and a half minutes.
First, Nampalys Mendy scored just his second goal of his entire career, a first-time screamer from the edge of the box into the top corner.
Following that, Kelechi Iheanacho squared for James Maddison to score after Wout Faes' tackle on Harry Kane at halftime ricocheted into his path.
Eric Dier of Tottenham defended Iheanacho as he fired a shot into the bottom corner to give Leicester a third goal before halftime.
Although Harvey Barnes had a goal disallowed for offside by the video assistant referee, Spurs did not take the lesson to heart and the winger sunk a fourth goal from James Maddison's pass 10 minutes later.
Spurs lost their goal scorer Bentancur to a knee injury after an hour due to a tackle on Mendy, capping off a truly awful afternoon.
Foxes are currently in 13th place, six points above the relegation zone, while Tottenham is still in fifth place, one point off the top four.
Once more flying, the foxes.
With four wins out of five prior victories and four straight losses following, the World Cup killed Leicester's momentum.
But when combined with a draw against Brighton and a 4-2 victory at Aston Villa, this victory over Spurs demonstrates that they have now fully recovered.
Brendan Rodgers will be happy that Maddison is fully recovered from his injury, along with several new players and Iheanacho's third straight game-winning goal.
When Kristensen steered a corner into Bentancur's path for the opening goal, the afternoon had all the makings of being disastrous.
Aside from that one incident, the Danish Under-21 defender played well, clearing a ball off the line just before the goal and suddenly appearing in both boxes to pass and tackle.
When Mendy ran onto Bentancur's clearance to shoot past Forster, it was an unbelievable goal—his first in English football.
Faes may have taken a chance by tackling Kane in the center circle after receiving a warning for his earlier foul on the player. However, the stray ball traveled about 30 yards to Iheanacho, who assisted Maddison in scoring his second goal in as many games.
Iheanacho gave them the lead before halftime thanks to Harry Souttar's pass, and they had opportunities in the second half before two deft Barnes goals—one that was disallowed and then one that was allowed—put them in control.
Right now, this Premier League game must rank as the most entertaining. The most goals have been scored in a divisional matchup since Leicester was promoted in 2014 (76 in games against Spurs).
After suffering an Achilles injury earlier in the season, Rodgers was able to insert right-back Ricardo Pereira, who helped the party atmosphere even more.
There will be more.
