A sensational second half performance by the Blues, inspired by substitute Eden Hazard saw Chelsea claw back a two-goal deficit to earn a brilliant point at Stamford Bridge against Spurs tonight.
That point meant that Spurs could not overhaul Leicester City who are crowned Premier League Champions.
Hazard came on at half-time to turn the game around as the visitors raced into a seemingly unassailable two goal lad through Harry Kane and Heung-Min Son.
But back came the Blues, first from the boot of centre-back Gary Cahill, before Hazard curled the most exquisite right-footed curler from just inside the Spurs penalty area that Hugo Loris could do nothing about.
There was very little proper football played as Spurs were intent on hacking Chelsea into submission and had seven players booked, many for horrendous late tackling. Quite how referee Mark Clettenberg failed to send off at least two Spurs players beggars belief.
Moussa Dembele will almost certainly face a FA charge for gauging the face of Diego Costa as Clattenberg took no action, presumably he mist not have seen it.
Spurs lost all discipline as the Blues received form a stupor of an opening 45 minutes that looked as if they were going to gift the three points to their north London rivals.
But that was before Hazard entered the fray and single-handed tore the Spurs side apart.
His goal, the vial equaliser was justice over thuggery.
Even as the players left the pitch there was yet another brawl to contend with as scores were being settled off the pitch for those committed on it.
Chelsea had the first chance of the game, on four minutes, but his header from Willian corner inched wide of Hugo Lloris's left upright.
Must Dembele and Mikel squared up to each other three minutes later after a series of nips and tugs between them.
A Danny Rose blaster inched over Asmir Begovic's crossbar, as Spurs threatened the Chelsea goal rather than the Chelsea players.
That ended on 11 minutes when Kyle Walker kicked out at Pedro on the corner.
referee Mark Clattenberg opted for a telling off once again.
Cesc Fabregas had a wonderful chance to open the scoring on 27 minutes but his low, right food, zipped pas Lloris's right post. It. followed an excellent move which shared with clean berg giving Chelsea he drainage after walker hacked down Pedro. A challenge he right back was subsequently booked for.
Costa, quiet up. To this point, got in on the act with a fierce drive, but Lloris was quick to respond and tip the goal-bound effort over the bar for a corner.
But it was the away side who broke the deadlock on 36 minutes, when Harry Kane beat the terrible Chelsea offside trap to round Begovic and slide the ball home from close range.
Jan Vertonghen received a yellow card for pulling Costa's shirt. The striker raced to Clattenberg demanding action and was lucky to escape a yellow for dissent.
Spurs should have doubled the score with five minutes on the clock, but Gary Cahill blocked Heung-Min Son's, close-range shot.
Disaster struck two minutes a later as Branislav Ivanovic ga e the ball as in midfield and it was quickly fed to Son who raced into the penalty area and cooly side-dotted the ball gome.
Willian and Rose then got yellows for a senseless clash which saw Spurs boss Maurico Pochettino enter the pitch to separate them.
Also TV replays showed that Dembele gouged Costa in the eye.
Eden Hazard entered the fray at halftime at the expense of Pedro.
Erik Lamela was straight into the ref's book with a lunging late tackle on Fabregas on 50 minutes.
The Blues got themselves back into the game on 58 minutes when Cahill, had two bites on the cherry from a corner and slammed home a sweet left-footer through a melee of defenders.
The equaliser came with seven minutes on the clock and it was started and dis shed in sensational fashion by Hazard who lashed home a curler from the edge of the box.
The whole of Leicester must have jumped up and down at that point, equal only to the 10s of thousands of Chelsea fans who realised their dream of denying their bitter struggle rivals the win they needed to keep their title dreams alive.

Asmir Begovic, 5
Not as commanding as he needed to be in the second match replacing suspended Thibaut Coutois. A tad late for Son's goal, going to ground early but redeemed himself by thwarting Ryan Mason
Branislav Ivanovic, 4
Poor in possession, poor in positional play. Unsure whether to attack or defend, he did neither with any conviction.
Cesc Fabregas, 5
He wore different coloured boots and to be honest I reckon they were both left ones as he certainly played as if he had two left feet.
He was outmuscled in midfield and could not dicta tithe pace of the game, something a successful Chelsea side needs him to do
A Guus Hiddink favourite and why not? Notthing inspirational ever comes form the boots of Mikel and he delivered what was expected
Off at half-time for Eden Hazard. Could have come off after a minute such was the paucity of effort or contribution
Diego Costa, 6
The first half was all about him sulking and feeling a sense of injustice - awww, shame.
He clearly was given a talking too at the break by Hisdink as he came out prepared to work
Nemanja Matic, 5
All the ugly closing down stuff that allows Hazard and Cesc to flourish was there in spades. Shame he doesn't have the attacking prowess in his locker to be the complete modern midfielder
He and Danny Rose exchanged so many nips and tugs and sly kicks, it stopped the wide man from being an effective attacker, which no doubt was Rose's intention.
Gary Cahill, 5
He scored the opener for the Blues and generally was much happier now that John Terry was back to ease the pressure off his shoulders.
John Terry, 6
The youngster has some future in the game if he continues to play like this. Fully deserves a new contract on this commanding dos play alone.
Cesar Azpilicueta 6
I'm happy to report 'Dave' was back to his best. Solid and reliable - a bit like a Volvo.
Sub: Marco Amelia,
On for Matic but nothing really changed .
Subs are supposed to affect the game for the better. Perhaps he wasn't told.
Eden Hazard, 9
Easily the best of the bunch and that was after only playing the second half, coming on for Pedro.
An immense performance, dragging ragtag Chelsea back into the game on his own. And let not forget that sensational equaliser. Just a shame the season does not start now
