Chelsea 0-0 West Ham United
Chelsea's bid to make it eight wins on the bounce was surprising thwarted by West Ham's stubborn resistance.
It was just one of those nights when no matter how much the Blues threw at the Hammers, it all came to nothing.
On another night, they might have matched the five Man City were hammering in at White Hart Lane, such was their dominance and the number of efforts on goal.
Even in injury time there might have been a late winner. Demba Ba hit a post, Eden Hazard flashed narrowly wide and the superb Adrian in West Ham's goal got in the way of a Frank Lampard strike.
There was also a controversial moment when Eto'o tried to cheekily poke the ball into the net after it had been left unattended by Adrian in anticipation of a free-kick.
Ref Neil Swarbrick decided Eto'o had jumped the gun but no-one was quite clear whether a free-kick had been awarded.
Chelsea, full of confidence at the outset, were soon in their stride, suggesting the evening would be a formality.
Oscar's curling shot from the left edge of the penalty area clipping the bar after getting a touch from Hammers keeper Adrian.
Willian whistled another effort just over the bar and the Hammers defence was panicked when a long ball launched from deep by Branislav Ivanovic caught them off guard.
Hazard, of all people, was on the end of it, heading back for the onrushing Eto'o, who blazed uncontrollably high and wide.
Even holding midfielders John Obi Mikel and Ramires got forward to take pot-shots as the Chelsea probing continued.
John Terry almost got on the scoresheet too at the end of the first half, when he rose highest to meet a Willian corner – only for Adrian to stop the downward header with his legs.
Eto'o also drew a fine near post save in first half injury time with a venomous low shot on the turn inside the area as Chelsea's sense of entitlement grew.
West Ham's fortitude also grew, however, and the longer the game wore on, the more they flung bodies in the way of an increasingly frustrated home side.
Joey O'Brien's sliding tackle from behind on Willian incensed Jose Mourinho and it was as much a symptom of the feverish tension building inside the stadium as anything else.
As was his reaction when the fourth official only awarded four minutes of injury time. Mourinho held up six fingers showing what he thought of it.
Mourinho sent on Nemanja Matic and Lampard just past the hour to try and force the issue and later Demba Ba.
But Chelsea's shooting became more erratic and from greater distances. Almost everyone bar Cech had a go at breaking the deadlock.
West Ham gave the Blues a bit of a scare after 12 minutes, but it was one of few genuine moments of danger from the east enders.
Centre half James Tomkins met Stewart Downing's free-kick from the left with a firm downward header and Petr Cech sprang to his right to turn the ball aside, but Kevin Nolan, lurking at the far post, was inches away from touching home the rebound.
Andy Carroll miscued in front of goal from a Downing cross in the second half, but the Hammers were mostly about heroic defending - and to be fair they did it well.
