Chelsea have had to keep their heads on throughout the game despite their lead as WBA have provided a threat in attack but the Blues have looked solid.

Deco whips a dangerous ball into the far post and Malouda is flying in but he can't keep a simple header down and it remains 3-0.

Close from the hosts as Donk chips the ball to the back post and Kim is there but although his volley is well struck it is wide.

All of a sudden Chelsea have become a little petty and started to kick out and go in hard for meaningless tackles and referee Bennett goes to John Terry to have a quick word.

The changes and the injuries have taken the rhythm and tempo out of the game a little in the last ten minutes or so.

Carson is back in action but he flaps at Deco's corner and Anelka has a great chance to score his hat-trick but he miskicks and the chance goes begging.

We have a bit of a stoppage here as Olsson, Lampard and Carson have all collided and all need some sort of treatment.

Bosingwa is running a very tight tope here as he now hauls down Greening on the left flank and with a yellow card he wants to avoid doing anything stupid.

Chelsea look so comfortable in possession today but West Brom boss Mowbray will be delighted that his side have not collapsed since the break.

So close to an immediate impact from Teixeira as he flashes a long range effort towards goal that skims the top of the crossbar.

Superb football from the visitors with Lampard and Malouda creating an opening for Anelka whose shot is blocked by a combination of Robinson and Olsson.

Another chance for Chelsea as Anelka unselfishly plays the ball across the box for Deco but Carson is across to smother the ball.

West Brom can't get the ball out of their own half and it is just wave after wave of attack from the Blues.

Chelsea are immediately on top once more and Malouda is fed by Anelka and he tests Carson once more from the edge of the box.

Those two quick goals have really given Chelsea control and they are strolling towards the break now.

Just five minutes to go in the half now and Chelsea now look to already have the game sealed up despite being dominated for long periods so far.

The visitors still look a little unsure of themselves at the moment as they fail to really find any attacking momentum.

And here come the Baggies! Koren into the channel for Miller who flashes it across goal but Bednar is the only man in the box and the ball is behind him.

Chelsea are yet to really find their rhythm this evening but WBA need to take advantage if they can before the Blues find their form.

Trademark from Frank Lampard as he collects the ball outside the box and smashes goalwards but Carson does well to turn it away from his near post.

A good, competitive start from both sides at the Hawthorns - the highest football ground in the country.

Terry and Ivanovic are struggling to contain the pace and power of Miller and Bednar at the moment and WBA are on top.

Salomon Kalou with Chelsea's first real chance as the tempo quickens a little but he can't keep his shot down.

Chance for the hosts! Morrison advances superbly forward again to feed Miller who tries to cut it across for an unmarked Bednar but the ball is just too hard and the danger passes.

Ishmael Miller is looking to test Ivanovic in the channels with his pace and at the moment the big defender is struggling to match him.

For the first time Chelsea are starting to get a foothold in the game and Olsson panics at the back and boots the ball away with Carson waiting to collect a harmless lobbed ball.

Lampard tries a delicate through ball towards Deco who has escaped round the back but the ball skips off the wet surface and out of play.

Nine of this Chelsea side today started the defeat by Burnley in midweek as they look today to return to the top of the table.

The hosts have made a really good start here and Chelsea are being forced onto the back foot for now.

James Morrison with a superb early effort for WBA from all of 30 yards that flashes a fraction wide of the far post.
