Saved efforts from Willian and Eto'o well, doing his push for a World Cup place no great harm but helpless for the Chelsea goal.
An awful day at the office for the defender. Bypassed countless times by Willian and not one of his passes reached a home shirt.
Sometimes out of the game when Chelsea ran rings around him but got forward well and linked up with Berahino excellently.
Kept up well with play and sometimes made marking Hazard look easy. Could not be held responsible for the goal.
Tested many times by the visitors and responded well apart from a momentary lapse which led to the Chelsea goal. Had a few headed opportunities from corners, too, but they were well wide.
A disappointing outing for the usually trustworthy midfielder, outclassed in midfield by Matic and Ramires. Taken off for Mulumbu.
Provided plenty of energy in the midfield and played a few through-balls to the attack. Weak in defence but not a bad performance from the fans' favourite.
A captain's performance in attack and defence. Put in a few good crosses from corners and from open play but they went unconverted. Solid against Chelsea's attacks.
A very poor game for the experienced Frenchman. Not one of his dribbles down the line was productive and he neglected all defensive duties. Subbed for Anichebe.
A good home debut for the January signing. His pace and strength was a nightmare at times for David Luiz but his best chance was only lashed across goal when it seemed easier to score.
Brilliant for the Baggies all game long. The youngster had the Chelsea defence worried at times and provided an inch-perfect cross for Anichebe's goal.
Rarely threatened in the Chelsea goal and could do nothing about the West Brom equaliser. Solid when directly tested.
Rarely challenged and largely solid but ballooned a free kick over the crossbar.
Strong for most of the game and carried on despite playing with what seemed like an injury for the last 20 minutes. Beaten in height and strength for Anichebe's goal, however.
Solid throughout, though the goal was his most obvious contribution, and the only thing to ruin his game was an argument with referee Howard Webb, for which he was booked.
Another Chelsea player who was rarely tested but occasionally looked vulnerable to Vydra's pace.
Very much the pantomime villain at this ground after the reverse fixture but struggled to get into the game and was substituted for Mohammed Salah.
A very good display from the young Brazilian. Ran Ridgewell ragged, put in the corner leading to Ivanovic’s goal and had a few attempts himself. Harshly booked for a clash with the left-back.
Rarely called upon in his role as a holding midfielder but swept up nicely and looked solid.
An unspectacular performance from the Brazilian midfielder. Offered little to threaten the goal but ably supported Willian and Hazard in midfield. Taken off for Mikel.
The Belgian forward's stellar recent form stuttered at the Hawthorns as he looked lost as many times as he did dangerous.
A constant thorn in the side of the West Brom defence. Used his pace effectively against the sluggish home back line and created a few half-chances but nothing more, with a lack of service at times preventing him from doing as much damage as possible.
Replaced Yacob when he was getting tired and looked a lot more lively in the midfield department. Got forward well and put in a few crucial challenges.
Provided plenty of energy and running up front. Despite not being the strongest he was very agile against Azpilicueta and looked dangerous at times.
Very lively up front when he came on for Thievy. His strength was a huge problem for the away side and he got just enough contact on the ball to guide it past Cech to equalise.
J. Obi Mikel
Brought on for Oscar and did not have much to do in the late stages of the game but defend, which he did well.
Brought on late as an attacking option just as Chelsea were put onto the back foot and saw little of the ball.
On the occasions when the ball came to him, the Spaniard looked alive, but those times were few and far between.
