Chelsea again try to respond in what has become an incredibly open game, with Hazard posing problems but West Brom looking menacing on the break.

Eto'o is cautioned for his celebrations and Long follows him into the book moments later after a barge on Terry in the Chelsea box.
GOAL! Eto'o makes it 1-0 to Chelsea as he takes advantage of some terrible defending by Ridgewell. Hazard creates the goal with a neat run and shot from the left-hand corner of the area, but Myhill pulls off a great save down low to his left and the ball should be cleared. Ridgewell inexplicably lets the ball run across his body and Eto'o nips in with another poacher's finish.
The Stamford Bridge faithful have had nothing to shout about yet but there is a slight buzz of anticipation as Hazard attempts a dribble down the left wing before being tackled by Reid.
Chelsea's build-up play continues to be too slow to trouble West Brom and passes are going astray far too regularly, with Eto'o the latest player to just stroke the ball straight out of play.

Yacob has already been booked and now midfield partner Mulumbu receives a final warning after being fooled into fouling Eto'o by a quick piece of footwork from the Cameroonian.

Brunt wastes the opportunity to deliver an effective cross from the left as it is cut out low down by a diving Cech.

Bilal in Dubai says: "Mou needs to fire the team up. Lamps has been a bit too quiet, with Willian slowly blossoming. 3-0 to Chelsea - Hazard brace, Ramires one late."
Toby writes: "Hi, Chelsea to win 2-0 with Eto'o and Lampard to score! Chelsea will do well being at home and all. COME ON BLUES!!!"

The team news for Chelsea is that Samuel Eto'o again leads the attack in the absence of the injured Fernando Torres, while Hazard does start in a supporting role along with Oscar and Willian. West Brom are without former Blues forward Nicolas Anelka because of injury, so Shane Long will operate in the lone striker role with fit-again Victor Anichebe on the bench.
Chelsea: Cech, Ivanovic, Cahill, Terry, Azpilicueta, Ramires, Lampard, Willian, Oscar, Hazard, Eto'o. Subs: Cole, Luiz, Mata, Mikel, De Bruyne, Ba, Schwarzer.

SKY BET: Chelsea start hot favourites courtesy of a 100 per cent League record at Stamford Bridge with West Brom 9/1 shots to produce one of the upsets of the day. The Blues have averaged nearly three goals a game in their last 26 Premier League 3pm kick-offs and punters have latched on to this stat seeing the price on Mourinho's men scoring 3+ goals 6/5. Samuel Eto'o, who scored twice against Schalke in midweek, is 100/30 to net the first goal.
West Brom will be determined to capitalise on any suggestion of fatigue and follow up their 2-0 triumph over struggling Crystal Palace. The Baggies have already won at Old Trafford this season and drawn with leaders Arsenal so they will be relishing the challenge, and manager Steve Clarke would no doubt love to get one over his old mentor after working as the Portuguese's assistant during his first stint at Chelsea.
Neil is the first to get in touch, saying: "Get Lamps to play attacking midfield - creative and a goalscorer."
Chelsea's 3-0 victory over Schalke was the perfect response to a surprise 2-0 defeat at the hands of Newcastle United last weekend, but Mourinho has criticised the scheduling of their game against West Brom as he feels it is unfair they are the only team asked to play on Saturday after being involved in the Champions League.
One player who will be involved again for Chelsea today is Eden Hazard after a midweek European adventure which saw him make the trip across the channel to watch former club Lille without permission, before losing his passport on the way back and missing his train. He apologised for his late arrival but was left out of the Champions League game against Schalke, with Jose Mourinho now ready to welcome the Belgian back into the fold.
