Corner to Chelsea. Terry almost gets to it at the near post to head goalwards, but it's deflected over for another corner.

Chelsea substitution: Anelka is replaced by Sturridge for stoppage time.

Free-kick again for Chelsea in a dangerous position 25 yards out. This time it's for a foul on Anelka by Salgado.
Chelsea have really struggled to get any rhythm back in their game since the Blackburn goal. This could be an important last 10 minutes in this season's title race.
Free-kick to Blackburn 35 yards out on the left. Pedersen takes left footed and it deflects up into the six yard box. Turnbull punches clear but N'Zonzi and Drogba are caught in the firing line and go down requiring treatment.
Almost an opening for Chelsea. Deco plays it down the left side of the area for Zhirkov. He digs out a dangerous looking cross, but it just beats everyone in the centre and flies away to the far post.
Chelsea substitution: Kalou comes off to be replaced by Deco.
Drogba takes right-footed. He sides-foots it with pace, but it goes straight into the Blackburn wall.
Drogba is challenged from behind by Pedersen, 25 yards out. It looks like the Blackburn man gets the ball, but it's a free-kick in a really dangerous position.
Blackburn 1 Chelsea 1: It's game on at Ewood Park now. Salgado's right-wing cross is headed powerfully home at the far post by Diouf from six yards.
Great cross-field ball by N'Zonzi finds Pedersen on the left side of the area. He chests it beyond Ferreira with his first touch, but instead of blasting goalwards from the tight angle he opts to loop a cross in which goes well over everyone.
Roberts goes down inside the Chelsea penalty area, but there's no foul and the game goes on.
It's turning into a more scrappy affair in this second half. Blackburn have showed much more endeavour than they did in the first half. Chelsea, whilst not at their best are looking to dig out an important win.
Diouf gives the ball away on the edge of his own area. The ball ends up with Anelka, but his left foot shot is tame and bobbles straight through to Brown.

Ferreira plays the ball off of Diouf on the right and it goes behind for a Chelsea corner.

N'Zonzi launches a lobbed pass forward for Pedersen inside the Chelsea penatly area, but he's gone too early with his run and the flag goes up.
It's been a much better start to this second half from the home side. They haven't created any real opportunities, but they've actually looked interested in pushing Chelsea back and trying to make something happen in the game.
Another long throw from Pedersen on the left. He hurls it in towards Samba but Drogba gets a good clearance on it.
Lampard fires one at goal from 25 yards. It moves in the air and has Brown scrambling across, but it goes just wide.

Blackburn 0 Chelsea 1: Drogba's early strike gives Chelsea a deserved lead at the break. The visitors have dominated the half against a very flat Blackburn side.
There will be two minutes of added time at the end of the first half. Sam Allardyce will be happy to get his side in at 1-0 and have a chance to re-group. It's been all Chelsea in this opening 45 minutes.
Chelsea substitution: Ivanovic has not recovered from that knock and he's coming off to be replaced by Yury Zhirkov.
Ivanovic was injured in that tangle with Diouf and he's still off the pitch requiring treatment.
Diouf concedes a corner under pressure from Ivanovic. It looks like Ivanovic got the final touch but Diouf should have cleared it much earlier.

Drogba flicks the ball on towards Anelka. Olsson gets to the ball first, but makes a needless error in mis-kicking behind for a corner.

Drogba goes down under an aerial challenge from Samba and he looks to be winded after landing awkwardly.
Lampard crosses from the right. Kalou gets up to head home but he just can't get his head on it as the ball drifts away at the far post.
Diouf plays a ball forward down the left for Dunn and he earns a throw-in 10 yards from the corner flag off Mikel.
Dangerous looking cross from the right from Anelka looks for Drogba, but Blackburn just get it away.
Andrews plays a long free-kick forward from the half-way line. Samba challenges for it and the ball is only half cleared to Pedersen on the edge of the area, but he can't keep his volley down and it flies over the bar.
Chelsea are pressing forward with alarmingly regularity for Sam Allardyce's men. He'll be keen to see his men start getting on the ball more and pushing Chelsea back the other way.
The corner drops to Alex 15 yards out. He volleys goalwards, but it's charged down bravely and Blackburn clear.
Decent opening for Chelsea again. Anelka get away on the right. He crosses low for Drogba, but the Blackburn defence just crowd him out at the expense of a corner.
Kalou does well to beat Diouf on the right. He crosses low for Anelka who can't guide his first-time effort on target from eight yards. He'll probably feel as though he should have hit the target at least.
Decent passage of play from Blackburn. They work it inside then out to the right for Salgado who earns a corner off Ferreira.
Kalou plays it down the left channel for Drogba. He crosses early towards Anelka, who gets to the ball first, but his touch just gets away from him and Brown comes out to claim as Anelka goes down.
Pederson takes left-footed. Turnbull should save it comfortably, but he mis-handles it behind for a corner.
Dunn gets brought down by Alex 25 yards from goal and central. It's a free-kick in a dangerous position. Dunn tries to play it quickly for Kalinic inside the area, but the referee pulls them back as Kalinic fires wide.
Blackburn enjoy their first spell of the match. They get Kalinic down the left in space, but he can't wrap his foot around the ball and his cross ends up on the roof of the net.
Olsson gives the ball away cheaply to Drogba just inside his own half. Drogba tries to find Anelka with a forward pass, but he too wastes possession and the ball runs through to Brown.

Diouf loops the ball behind the Chelsea defence looking for Kalinic, but Turnbull races out to claim right on the very edge of the area.
Kalou attacks into the area and wins a corner. The first attempt is put behind again for another corner to the visitors. It's been a really fast start for Chelsea.

Anelka tricks his way beyond Diouf 35 yards out. He plays it inside for Drogba, who tries to curl one for the far post, but he doesn't really get the contact he'd like and the ball goes wide.
Dunn strides forward towards the Chelsea area. He tries a little ball behind the Chelsea defence for Kalinic, but the flag goes up as the ball runs on through to Turnbull in the Chelsea goal.
Early ball forward looks for Drogba, but Brown is out fast to gather the ball.
Rovers get this first half underway looking to extend their impressive home run.
Ancelottis men have won only twice in the last seven away games in the league. However, they only failed to hit the net once all season a 0-0 draw at Birmingham on Boxing Day.
The hosts are coming into the game on the back of back-to-back defeats and a loss today would be their worst run of defeats since Allardyce took charge in December 2008.
Blackburn have shown some fantastic home form of late. Theyve won the last four successive games and kept clean sheets in three of those.
A goal for Rovers against Chelsea could prove encouraging as they have not scored against todays visitors since Steven Reid netted an Ewood Park winner in May 2006.
Chelsea have won all of the last five league encounters against Blackburn since they drew 0-0 at home in September 2007.
Sam Allardyces men have lost only twice at home in the league all season and face all three of the title contenders in the run-in.
After heading out of the Champions League in midweek, Chelsea will be looking to bounce-back against a Blackburn side who knocked them out of the Carling Cup. Chelsea, however, did win the reverse fixture 5-0 against Rovers back in October.
Paul Robinson picked up a torn calf muscle last time out against Tottenham and so Jason Brown will deputise in the Blackburn goal. Blackburn are also without Ryan Nelsen, Gael Givet, Lars Jacobsen, Vince Grella and Franco Di Santo.
Chelsea team line-up: Turnbull, Ivanovic, Alex, Terry, Paulo Ferreira, Mikel, Kalou, Malouda, Lampard, Anelka, Drogba
Blackburn Rovers team line-up: Brown, Salgado, Samba, Jones, Olsson, Andrews, Nzonzi, Dunn, Pedersen, Diouf, Kalinic
