A sensational second half where six goals flashed past distraught goalkeepers was only part of the drama as Chelsea and Everton battled out a 3-3 goal-fest at Stamford Bridge.
The home side looked to be heading for a thrashing as Everton raced into. 2-0 lead through an own goal by John Terry and a wonder strike by Kevin Mirallas.
But Diego Costa dragged the relegation-haunted Blues back into the game when a defensive mix-up gave him the simplest chance to tap home.
Then Cesc Fabregas sent the home crowd delirious with an equaliser, albeit a deflected one, before Everton looked to have won it late ion when substitute Ramiro Funes Mori hooked the ball home on 90 minutes.
Seven minutes of added time were ordered by referee Michael Jones, mostly for an treatment to a Bryan Oviedo injury.
But a minute after the allotted time, Terry, seemingly from an off-side position clipped a deft back heel home For an underserved qualifier.
The early stages of the game were tight, with no inch given by either side. The only notable action being Mikel too fast and getting clattered by ex-Spurs man Aaron Lennon.
One quick breakaway on 16 minutes saw Willian latch onto a Branislav Ivanovic pass and race into the Everton area. the Brazil midfielder unleashed a thumper of a shot which Tim Howard, coming off his line tipped the ball over his crossbar for a corner.
Bryan Oviedo scuffed an excellent chance to putt he Toffeemen ahead three minutes later but the ball inched just wide of Thibaut Courtois's goal.
A half-hearted effort by Ex-Blue Romelu Lukaku was easily held by the Chelsea goalkeeper, but the Belgium was fully extended with six minutes to go when he brilliantly got down low to his left to thwart a daisy-cut from Lennon.
There were no changes from either side at half-time.
But the home side made the worst possible start five minutes in. With the ball won by Ross Barkley, Everton pushed forward en masse.
Lukaku powered I to the final third before feeding the ball wide. It fell eventually to Leighton Baines who cut the perfect left, byline cross and unfortunate for Hohn Terry he mad a has of any attempt to clear and let the ball twice hit his legs before it inched over the goal line.
Barkely almost doubled the lead when a powerful left-footed drive, beat Courtois but rattled his right post.
Interim boss Guus Hiddink had to make a change and Oscar was introduced at the expense of ineffectual Nemanja Matic on 55 minutes.
It made no difference as the home side went further behind within a minute.
Once again a break saw the Blues defence crumble as Lennon passed the ball wide to Baines. Again he send in the cross and this time Kevin Mirallas picked up the ball, took one touch, unchallenged before sending in a rasping left footer past Courtois.
A fantastic reaction save from Howard to tip away a clipped, back-heel by Fabregas halted a quick Chelsea recovery goal on 60 minutes.
But the goal came and from a long ball too. Diego Costa outmuscled Phil Jagielka and when Howard failed to hack it clear, the striker found himself all alone in the six-yard box and slotted home.
The equaliser was but a minute away and sent the 41,633 into raptures. On the edge of the Everton penalty area, Costa back-flicked the ball to Fabregas, who found a extra bit of space before sliding the ball past a hapless Howard off the shin of Muhamed Besic
Oviedo was then carried off on a stretcher after a nasty, albeit innocent collision with substitute Kenedy on 78 minutes.
Costa limped off with what looks like a knee injury with 11 minutes on the clock. Loic Remy entered the fray in his place.
But with the fourth officIal about to put up the added time board for seven minutes, the visitors took the lead again.
The simplest of crosses from substitute Gerard Deulofeu saw Lukaku and substitute Ramirio Funes Mori completely free at the fat post and it was Funes Mori who clipped the ball, almost on the goalie past Courtois.
But the drama did not end there and in the eight minute of added time, up popped Terry to make amends for his own goal to tap the ball home from six-yards out with a deft poke.
He was clearly offside, but the crowd did not care, nor do the Chelsea players who clearly got out of jail and preserved interim manager Guus Hiddink's undefeated run, which read one win out of five. Not great but this point feels like three.
Next up is the little matter of a trip to Arsenal.
