Chelsea still cannot win under Rafa Benitez as they were humiliated 3-1 by a resurgent West Ham United at Upton Park this afternoon.
That's now no wins from three games and just two points from a possible nine.
The Blues took the lead through Juan Mata and on possession a lonely should have blown away their opponents.
But a sensational second 45 minutes from the home side, destroyed the champions of Europe as goals from Carlton Cole and a goal apiece from substitutes Mohamed Diame and Modibo Maiga which turned the match on its head.
West Ham certainly looked the team most likely to break he deadlock in the opening exchanges, in particular from set pieces.
Chelsea, by contrast looked bet in possession, and so it proved on 12 minutes when Juan Mata started a quick move from a throw in.
He passed wide on the right to Victor Moses. The winger curled a low right-footer behind the Hammers rearguard to an on-running Fernando Torres.
The Spain striker cut back a byline cross where Mata, following up in the penalty area, struck a low left-footer past goalkeeper Jussi Jaaskelainen to put the visitors 1-0 up.
On 16 minutes, the expected chants from the Chelsea fans for fallen manager Roberto Di Matteo roared out from the Sir Trevor Brooking stand.
Present incumbent Rafael Benitez, the subject of the fans ire stood by the touch line, seemingly oblivious to the dissent, and concentrating on the game.
The Blues should have doubled their lead on 20 minutes, when Ramires stole the ball off Guy Demel and passed to Mikel. However the midfielder tried a first-time shot on goal, from 12 yards out, which he got hopelessly wrong and the ball drifted wide of goal.
Fernando Torres had a great chance on 25 minutes, when, following Mark Noble giving the ball away cheaply, the Blues raced clear upfield through Mikel. He passed the ball square tonTorres on the edge of then West Ham penalty area, but preceded to sky the ball over Jaaskelainen's crossbar.
The Blues continued to dominate pressure without duly putting pressure on the home side's goal. Mata, on 32 minutes, tried to do it by himself but curled the ball over the net from close range.
The Hammers had the ball in the back of the Chelsea net a minute later when Kevin Nolan's overhead kick, six yards out beat Cech. However referee Martin Atkinson disallowed the fine effort, adjudging that James Collins had committed a foul in the area just before.
Jaaskelainen was called into action with four minutes of the half remaining. Moses tormented Demel on the left, twisting the blood out of e right-back, before cutting the ball back. It fell invitingly to Mata who arrowed a left footer on goal, but the Finnish goal stopper was equal to the task punching he ball to safety.
Cech was handed a yellow card, by Atkinson, for punching the ball from outside his penalty area on 44 minutes.
From the resultant free-kick Cech produced a fine save when. Nolan header appeared destined for the top left hand corner of the Chelsea goal. Sam Allardyce made two halftime changes bringing on Matt Taylor and Mohamed Diame for Gary 'ONeil and James Tomkins.
The effect was instant with West Ham piling on the pressure from the restart and unlucky on two occasions when Carlton Cole headed just over from a Matt Jarvis cross, and Cole unluckily got in the way of a Nolan pile-driver when the ball seemed detained for the ball of the Chelsea net.
A desperate goal-line clearance from Gary Cahill denied Mark Nolan on 57 mInuted as the home side forced the Blues further back.
They got their just reward on the 63rd minute when ex-Blue Carlton Cole simply wanted the ball more against Cahill and out jumped the centre-back from six yards out to head the ball past Cech to level the scores.
Chelsea, stung by the goal, responded brilliantly and Jaaskelainen did well to beat out two efforts in quick succession firstly from Mata and then from Torres.
Mata then thundered a 20-yard free-kick against the goalkeeper's left upright as the game exploded with end-to-end action.
With cries of "You don't know what you're doing", from the Chelsea faithful, Benitez replaced Hazard for Oscar with 18 minutes remaining.
This was quickly followed by Marko Marin entering the fray for Moses on 78 minutes. West Ham's Javis should have put the home side ahead when he was sent clear with nine minutes remaining but Cech parried the drive away for a corner.
From the resultant kick, Ashley Cole headed the ball off the line from Collin's powerful header.
Chelsea retaliated with an Oscar blaster from just outside the Hammers penalty area, but the fine effort went just over the crossbar.
West Ham's turnaround was complete with four minutes to go as substitute Mohamed Diame latched onto a simple pass from Carlton Cole to drill the ball home past Cech from 10 yards out.
The Blues, by now completely demoralised conceded a third deep into injury time as Diame had the is pleat of chances to tuck home from close range after Cech could only parry out into his path a byline cross.
