Close again! Matt Taylor screws his shot across goal but there are no Bolton players on hand to roll it into the empty net.

Chance for Chelsea to finish it as Joe Cole races through but he is denied by Jussi Jaaskelainen.

Another chance comes and goes for Bolton as Ivan Klasnic swivels in the box but screws his shot wide of the post.

Big moment! Good work from Robinson and Taylor on the left to set up Elmander just six yards out but he fluffs the header and Chelsea escape.

Suddenly Chelsea have come alive again with Malouda's corner headed narrowly wide by John Terry.

Joe Cole, where have you been?! Wonderful flick with his first touch to set up Lampard who hits the post and with his second he tees up a cross for Ballack who heads straight at the keeper.

Bolton can sense the equaliser here as Chelsea withdraw into their shell even further and although still dangerous on the break with Drogba they are under the cosh.

Jack Wilshere has shown why he is being so talked about at Arsenal with two brilliant touches here to hold off Terry and set free Muamba but the big midfielder blazes over.

Chelsea need a second goal here because they are beginning to look a little nervy now and Bolton have harmed them late on in games before.

Chung-Yong Lee has been getting rave reviews for his bright displays this season and he has been decent again tonight but he fails to beat the first man twice here when well placed to deliver a telling cross.

Not that I wish to doubt the man who could be leading his side four points clear at the top but Michael Ballack has been anonymous so far while Kalou has been awful so why has Anelka been withdrawn?

Bolton immediately now on the break with Taylor in behind but he does not have the pace to run away from the recovering Chelsea defenders who catch him before he can get his shot off.

Yuri Zhirkov plays a clever one-two with Lampard and fires a stinging drive towards goal but its well parried.

The Bolton players are still livid with the referee and with good reason but they almost pay for a lack of concentration as Drogba sneaks in but can't find the target,

Oh dear, oh dear, oh dear! Messrs Ferguson and Wenger will be as unhappy as Owen Coyle as John Terry clearly sticks out an arm to block Lee's goalbound shot in the area but somehow the referee misses it. Shocking decision! Lucky for Chelsea and Terry

Super tackle! Paolo Ferreira looks to be in on goal and is just pulling the trigger until Matt Taylor slides in in the nick of time to deny him. Perfectly timed!

Kalou is not having the best of games so far and with Malouda and Joe Cole he will probably be heading off soon - and as if to rub salt into the wounds he blazes over from 12 yards when well placed.

Should be game over! Salomon Kalou is found cleverly by Aa combination of Anelka and Drogba but his shot is straight at Jaaskelainen who spread himself well.

Chelsea were hardly free-flowing before the break and since the interval they have not really improved. Do they need another goal? Well Bolton have not scored for a month so maybe not?

Mikel gets himself into an advanced position but seems to almost panic at the vital moment at being so far forward as his shot is wild.

Good start to the second period from the visitors with Robinson advancing down the left but Alex is there to deny Davies before Wilshere fires wide.

Chelsea are going for the jugular now as Terry, Ferreira and finally Kalou all flash efforts goalwards. Bolton are holding on for dear life here.

He's on - and he's off again! Zhirkov trots back on, wins a header and promptly has to go back down the tunnel again for another new bandage.

Zhirkov has been sent back to the touchline to get patched up again as blood begins to trickle down the side of his face from that earlier cut.

Here comes the pressure as Chelsea suddenly begin to up the tempo and Bolton can't keep the ball or clear it out of their own half.

Yuri Zhirkov, despite his head wound, is having a really good game and seems to be enjoying the freedom that he has been given to attack from his left back berth tonight.

A lull in proceedings now as we pass the half hour mark and Chelsea may need to change tact if they are going to be break through before the break because Bolton are looking good.

Half chance for Chelsea but it falls to John Terry and the skipper scuffs his volley, when unmarked, from Lampard's corner.

Drogba whips in a free-kick that Jaaskelainen, for some reason, decides to punch straight into the face of Salomon Kalou who watches on as the ball rolls agonisingly of the post. Scare for Bolton.

Zhirkov is back, and he is complete with the trademark bandage wrapped all around his head. He gets a very warm applause though.

Superb defending and brave too! Ricketts looped cross looks sure to be headed in by Kevin Davies at the far post but Zhirkov stretches his neck to flick the ball away, only for Davies to head the Russian's head.

Bolton are growing in confidence now and they are getting better by the minute. Very frustrating for the title favourites so far.

Great chance now as Matt Taylor escapes Zhirkov and beats Cech only to see his shot cleared off the line by Paolo Ferreira. Big escape!

Still goallless as Chelsea struggle to open up a well organised, thus far, Trotters backline.

Good news for Terry, Chelsea and England as the Blues skipper jogs back into the action and seems to be moving freely now.

John Terry makes a good block to deny Matthew Taylor whose half volley was heading on target but the big centre half is injured now and requires treatment.

Chelsea are starting to take a bit of control now as they pass the ball around nicely in the midfield but no real goal threat yet.

Nicolas Anelka gets the first shot of the match in on goal but its very tamely struck and Jaaskelainen gathers easily.

Lively start at the Bridge with both sides looking to attack - it is by no means a defensive lineup from Owen Coyle so this could be an interesting game.
