FULL-TIME: Action-packed game ends with deserved victory for the visitors. Thanks for joining me and stay logged on for reports and reaction from the Stadium of Light.
GOAL CHELSEA: Game over now as Anelka makes the points safe. Good play by Malouda and fellow Frenchman Anelka taps in from close range.
Last change for Chelsea as Bosingwa strolls off to be replaced by Ferreira. Plenty of boos from the home fans
Chelsea are controlling the pace of this game now; they seem happy to settle for 3-2. Sunderland need to find a little more urgncy to get anything from this match.
A mass coming together of players from both sides and Mark Halsey has to caution Richardson and Ivanovic. The Sunderland player booked after kicking the ball at Bosingwa in frustration.
Can Sunderland find some energy from somewhere to force the issue? They need to try and step it up as Chelsea are looking comfortable in possession.
Elmahamady brings down Cole as the full-back breaks forward. Drogba takes the free-kick but Ferdinand gets up well to clear the danger.
Bosingwa finds space out wide and crosses for Kalou who is flagged offside. Chelsea have looked irresistible tonight. You have to ask where will Fernando Torres fit in?
How did that stay out? Anelka glides forward and opens the defence. He feeds Kalou whose shot hits both posts before being cleared. What an escape for the home side?
Another save from Gordon to deny Lampard. The Scot has been in great form to deny the England midfielder. Sunderland need to get a grip on things or the Blues could run away with this.
GOAL CHELSEA: Terry puts the visitors ahead with a great finish. Gordon makes an incredible save from Lampard but Terry's shot loops over him and in. Hard on the Sunderland keeper but the Blues deserve their lead.
Kalou looks to play a 1-2 with Drogba but Sunderland stand firm. Then Gordon gets down smartly to deny Lampard.
Lampard denied by Gordon. Chelsea really should be ahead now - that's three great chances in the opening moments of the second period. Sunderland are rocking.
Kalou's cross is deflected into the path of Lampard whose effort is scrambled away by Gordon. Another scramble from the resulting corner but Malbranque and the post somehow keep Chelsea out. What an amazing minute.
The teams are on there way out. It's a balmy night in the north-east (well relatively) so why Anelka thinks he needs gloves only he knows.
Thomas and Jack are both predicting a 4-3 scoreline in Chelsea's favour while Jonathan says: "I'm on the train gripped onto every update. Come on Sunderland. 3-2 Gyan with 5 mins to go."
Louis has been in touch to say: "That was a great first half, many goals in the second half and Sunderland to win 4 - 3" while Nicky adds: "c'mon chelsea you can do it!. 4-2 to the mighty Chelsea."
Must give a mention to my Sunderland-loving former colleague Lisa who's hanging on my every word tonight. I can't promise it'll be good news Lisa but it'll certainly be entertaining.
Email in from Craig asking: "Chris, watching your blog on internet, can you tell me how Stephane Sessegnon is playing, does he look out of place? Does he look worth £6m? Well Craig he's shown some nice touches but I bet he can't believe the pace of this game!
HALF-TIME: What a great 45 minutes that was. Full of action and goals. More of the same please. I've got 15 minutes to get my breath back. Send me your comments on that first half please - firstname.lastname@example.org
Richardson hammers in a powerful shot but it's parried by Cech who looks unusually uncertain this evening.
Lampard's corner finds the head of Drogba but his effort is straight at Gordon. Another great chance.
Off the bar. Ivanovic drives it against the woodwork from just six yards out. What a game this is. Thought it may be an anti-climax after the Torres saga but not a bit of it.
Essien's effort is deflected but Gordon recovers to make the save. Justice as there was a clear foul in the build-up.
GOAL SUNDERLAND: Elmahamady wins his side a free-kick as he's taken down by a combination of Mikel and Ivanovic. Richardson's free-kick evades the wall and Cech is helpless as it slides into the corner.
Sunderland look to get back on terms but Terry is alert to the danger. The home side have been the architects of their own downfall so far.
GOAL CHELSEA: Great finish from Kalou who is put through by Anelka. Gordon rushes out to meet him quickly but he clips the ball beyond the Sunderland keeper. What a sucker punch.
Lampard looks to thread a ball through to Anelka but Bramble sticks out a long leg to tidy up the danger.
Drogba clatters Bardsley and Sunderland win a free-kick. Good game this. Enjoyed the opening encounters.
GOAL CHELSEA: Lampard hammers it home from the spot with Gordon sent the wrong way. Sunderland pay a heavy price for that clumsy challenge.
Kalou and Lampard link up but the England midfielder fails to find his man with the return ball. Then Lampard gets an opening following a fortunate break but drags his effort narrowly wide.
Terry strides forward and links with Drogba but the return evades him. Terry appeals in vain for a penalty - Richardson certainly had a hand on the Chelsea skipper's back there.
The Blues are looking to get a quick reply and Kalou tries to work an opening but Sunderland snuff the danger and Richardson looks to counter.
Chelsea are stunned and seek a swift reply but Cole is denied at the expense of a corner. Drogba's set-piece goes all the way across the box and out of harm's way.
GOAL SUNDERLAND: Phil Bardsley fires one with his right foot from the edge of the box beyond an unsighted Cech who really should have done a lot better. Great start for the Black Cats.
We're underway now as Richardson chases a long ball pumped forward but it goes out of play for a goal kick to the Blues.
As we await kick-off here's an update from Sky Bet. They make Chelsea strong favourites at 8/11 while Sunderland are available at 4/1. It's 5/2 the draw.
The teams are on their way out of the tunnel. Stay with me for what should be a cracker if the earlier encounter at Stamford Bridge was anything to go by.
Frank has emailed in and says: "Look for both Drogba and Anelka to put forth huge efforts today - especially Nico who is most likely to give way to the newboy. They've got to feel just a little threatened with Torres coming and will know they need to start producing extra efforts if they are to remain at the heart of Ancellotti's plans. Would be great to see the rest of the team boosted by the support they are about to receive!"
Favourite pre-match tunes anyone? Welcome to the Jungle has to be up there or Ready to Go by Republica was an Elland Road favourite. Email me - email@example.com or sent me a Tweet - @skysportsed
As Welcome to the Jungle by Guns n Roses pumps out, Ali's in confident mood and says: "Chelsea to respond to the 3-goal home drubbing by going 1 better, Lampard (2),Drogba and Kalou. 4-0 to the Mighty Chelsea."
Blues fan Amarpreet adds: "Tough match but I think we should win 2-0 without Fernando Torres who without any doubt is a great player."
BJ Cook says: "Come on you red & white stripes!!! Who needs Torres when we have the mighty Richardson. 2-0 to the lads."
Tonight's subs - Sunderland: Mignolet, Mensah, Angeleri, Riveros, Colback, Cook, Reed. Chelsea: Turnbull, Ramires, Malouda, Ferreira, Bruma, McEachran, Sala.
@rayz_tweets has been in touch via Twitter to say: "Hopefully we can maintain more cleansheets and score goals through Torres...who no doubt is fantastic! 2-0 to Chelsea tonight!" No Nando but still plenty of firepower.
