Kelechi Iheanacho benefitted from a huge VAR assist as Leicester City continued to hang on to the coattails of Liverpool on a day when Arsenal started the post-Unai Emery era with a draw.
With Manchester City and Chelsea suffering unlikely setbacks on Saturday, Liverpool took the opportunity to extend their lead to 11 points and it appeared the Foxes were not well placed to cut that gap after falling behind at home to Everton.
However, a last-gasp technological intervention sparked wild celebrations at the King Power Stadium as Leicester completed a come-from-behind 2-1 triumph.
Also on Sunday, there was more frustration for Manchester United and interim boss Freddie Ljungberg saw Arsenal twice come from behind at Carrow Road.
FOXES GRATEFUL TO VAR
Leicester were in danger at the break after Richarlison headed home to put Everton into a half-time lead, while Ben Chilwell saw a penalty for a trip from Mason Holgate overturned by VAR.
Jamie Vardy's neat strike – his 13th in the league this season – brought Leicester level, though, before drama ensued deep into second-half stoppage time.
Iheanacho latched on to Ricardo Pereira's excellent throughball and rifled his shot past Jordan Pickford, only for the linesman to curtail his knee-sliding celebration.
But a check with the video assistant showed Yerry Mina had played the striker onside to leave Leicester in outright second and pile more pressure on under-fire Toffees boss Marco Silva.
SAME OLD ARSENAL
Emery may have departed Arsenal but it was a familiar story for the Gunners defensively under Ljungberg.
Norwich stole ahead when Kenny McLean was afforded too much space to pick out Teemu Pukki, whose deflected effort beat Bernd Leno after David Luiz had backed off the striker.
Pierre-Emerick Aubameyang levelled from the penalty spot at the second attempt having been handed a reprieve when his first attempt was saved by Tim Krul, only for VAR to spot an encroachment.
Aubameyang levelled again in the second half but only after more poor defending had seen Todd Cantwell put Norwich in a 2-1 half-time lead.
RED DEVILS STRUGGLE AT HOME
Manchester United were again off the pace in a 2-2 draw against Aston Villa, who led through Jack Grealish's stunning curling opener.
Marcus Rashford saw a header from Andreas Pereira's whipped cross cannon off the post and hit Tom Heaton on the back before nestling in the goal to bring United level and they led when Victor Lindelof nodded home in the 64th minute.
Just two minutes later, United were caught napping when Matt Targett clipped a second ball in from a cleared corner and Tyrone Mings volleyed past David de Gea.
DOHERTY PAYS TRIBUTE TO AFOBE
Two teams impressing in the top half of the table played out a 1-1 draw at Molineux as Wolves came back against Sheffield United – the visitors leading through Lys Mousset's second-minute goal.
Matt Doherty levelled in the second half and celebrated by kissing and raising his black armband, which was being worn in honour of former Wolves striker Benik Afobe, who announced the tragic loss of his two-year-old daughter Amora on Sunday.
