Frank Lampard scored twice as Chelsea returned to winning ways with a hard-fought victory over Blackburn.
The Blues were 2-0 up early on as Didier Drogba's deft header and Lampard's penalty put them in control.
But Rovers hit back as Craig Bellamy netted a penalty - then the same player headed the visitors level after keeper Petr Cech made a mess of a clearance.
But Lampard's wicked curling free-kick put Chelsea in front, before Joe Cole's deflected shot secured the win.
Yet the scoreline belied the fact that Chelsea were looking distinctly shaky at half-time after Rovers fought back from two goals down.
Amazingly, it was only the third time that the Blues had conceded more than a single goal in a Premiership game since Jose Mourinho took over as coach.
And the comeback goals were all the more unlikely as Chelsea took early control of the match.
Drogba's delicate 10th-minute header from Lampard's cross left Brad Friedel with no chance.
Then referee Mike Riley judged that Andy Todd had impeded John Terry as he went for a cross and Lampard slotted home comfortably from the penalty spot.
But Rovers were handed a lifeline four minutes later as Ricardo Carvalho clipped the heels of Zurab Khizanishvili inside the box.
Bellamy made no mistake, sending Cech the wrong way after his stop-start run up to the ball.
The goal halted Chelsea's momentum, although Asier Del Horno could have done better when he headed over from a pinpoint Lampard free-kick.
Blackburn then began to believe in themselves and Brett Emerton fired a warning as his low shot was pushed around the post by Cech.
Yet the Czech Republic international had to take the blame for Rovers' equaliser following an uncharacteristic blunder.
Cech horribly sliced Del Horno's bouncing back pass and Shefki Kuqi reacted first, heading across to Bellamy who nodded the ball into the corner.
There was tension between the teams and that was compounded after the break when Rovers boss Mark Hughes was sent from the touchline by Mike Riley, seemingly for something he said.
But the home fans notably relaxed as Lampard netted his 100th goal in club football in the 62nd minute.
The England midfielder curled in a wicked free-kick from the left and the ball crept in at Friedel's far post without touching anyone on the way through.
Lampard seemed eager to complete a hat-trick and fired a shot just wide before seeing another free-kick parried by Friedel.
But it was Cole who got in on the scoring act, his 20-yard shot taking a wicked deflection off Khizanishvili and flying past the helpless Friedel.
Chelsea were now rampant and Friedel saved from Lampard again and substitute Arjen Robben, while Eidur Gudjohnsen blazed narrowly over from a tight angle.
Chelsea boss Jose Mourinho on Frank Lampard:
"I don't know what those who organise these world awards do at the weekends because only English people recognise what this player is.
"He was the best player in the Premiership last season.
"You have some great players in the world but they play one game a month. This player is top in every game."
Blackburn boss Mark Hughes:
"I'm a little bit confused as to why the referee felt it was necessary to send me to the stand.
"I wasn't happy with some decisions. I jumped up to get the ref's attention but he ignored me so I kicked a bag.
"The fourth official, who I felt was a bit pedantic all afternoon, decided it was time for me to sit in the stand."
