West Brom's lack of attacking threat in the first half meant he was a glorified spectator. Did himself no credit in the second though, parrying McAuley's header straight into the air to allow Long to attack the rebound. Also let Sessegnon's tame effort creep under his body.
Given freedom to bomb forward down the right, his crossing was again very poor. That West Brom often left him in space on the flank was no coincidence. Beaten to the ball by McAuley in the build-up to Long's equaliser.
Solid again at left-back in the absence of Ashley Cole, though his attacking threat was blunted by being on the wrong flank.
Organised his backline well in the main, but appeared to freeze when Cech parried McAuley's header up into the air, allowing Long to attack the ball and head in.
Assured in possession and generally looked after Long well, although West Brom's lack of attacking numbers gave him an easy ride for much of the afternoon. Allowed Long to steal in front of him to unleash a header which struck the post.
Once again ineffective against a massed defence. Much better when he has space to run into, and this match was never going to highlight his talents.
Buzzed in between the lines and harried well when possession was lost, but this was nowhere near his most influential day. Still doesn't seem as effective against deep-lying defences as Mata.
Kept things ticking over reasonably well without creating too much danger. Unleashed one trademark shot from 25 yards which flew a couple of yards over the bar. Replaced by Ba just after the hour mark.
Stifled well by Reid and Amalfitano when he stuck to the left flank, but cut inside well to unleash the shot which led to Chelsea's opener. Scored the last-minute penalty which saved his team's blushes.
Sessegnon's brief to mark him meant the Brazilian could not be at his rampaging best. Used the ball sensibly without making a decisive impact. Definitely 'won' the last-minute penalty which secured the draw - Reid did very little wrong.
Took his goal well, but still doesn't seem to be in sync with the creative trio behind him. Starved of service for most of the afternoon.
Parried Hazard's effort back into danger for Eto'o's opener, but otherwise did well and had surprisingly little to deal with. Made a superb stop to deny Ivanovic in the second half.
Shackled Hazard well in tandem with Amalfitano on the left, ensuring the Belgian only caused problems when he drifted inside.
Stood up well to the barrage of crosses Chelsea put in and marshalled his defence superbly.
Defended his area well and provided a big threat from attacking set-pieces, beating Ivanovic in the build-up to Long's equaliser.
Made a bad gaffe to allow Eto'o to steal in and give Chelsea the lead, but redeemed himself brilliantly by jinking past Cahill to feed Sessegnon for the Benin international's goal.
Tactically disciplined, committed Chelsea players whenever he got the ball and left Terry for dead to score the winner. A performance to rival his Old Trafford heroics.
Showed great energy to get from box to box and helped ensure his side got the possession they needed to hurt Chelsea and then weather the ensuing storm.
Put in an excellent cross for Long to hit the post and doubled up well on Hazard.
Defended diligently and his set-piece deliveries were a constant source of worry for the Chelsea defence.
An excellent shield in front of his defence, not attracting much attention but preventing Oscar from ever sparking into life in between the lines.
Led the line intelligently, worked the channels and took his chance when it came, leaping salmon-like to bring his side level.
