Got lucky to avoid embarrassment when attempting to clear sloppy back passes from his defenders, with Caulker getting back to bail him out on one occasion. Not tested enough by a wasteful Chelsea attack and was powerless to stop either of the visitors' goals.
Put his goalkeeper under pressure with a poor back pass in the first half but redeemed himself on another occasion by getting back behind his keeper to prevent Torres giving Chelsea an early lead. Could not marshall his defence to withstand the Blues' second-half onslaught.
Fortunate not to give away a penalty when he hauled Oscar down in the third minute and looked troubled by Chelsea's attacking movement all afternoon.
Stood up reasonably well to the threat of Hazard and got forward to expose the Belgian's defensive weaknesses.
Never looked comfortable when Hazard and Salah took turns to run at him but prevented either from doing serious damage down his flank and got forward reasonably well.
Got no real opportunity to show his crossing ability in an attacking sense and proved a bit of a passenger when Chelsea had the ball.
Always tactically disciplined, hard working and impressive on the ball. Cardiff may be heading back to the Championship but if a smart club recognises his talent, he may not be.
Could not prevent Chelsea dominating the midfield battle or creating chance after chance, with only their wastefulness in front of goal getting him off the hook.
Showcased some neat touches and tidy technique without seriously influencing the game.
Blazed one shot wide of the near post after slaloming through several Chelsea defenders in the first half. Otherwise lively without ever seriously testing Schwarzer.
A typically lively display and marked what could be the final appearance of his career with the goal which put his team ahead, albeit with the help of a huge deflection off Azpilicueta.
Could do nothing about Bellamy's deflected strike and was otherwise almost entirely untested.
Much more of an attacking threat from right-back and an incisive run to meet Oscar's cross led to Chelsea's equaliser.
As impressive here as he was at Anfield, shackling Campbell with ease. Has a good future on this evidence.
There is not much he will want to remember about what looks like his final Chelsea appearance, even if he produced a typically reliable individual display.
Campbell only got past him once and could not make him pay. Always looks far more assured in the heart of defence.
Still the most consistently incisive passer in this Chelsea midfield and his physicality provided the platform for his side's dominance of the ball.
There were isolated classy touches but this was not the Belgian's most influential day. He also let Fabio fun beyond him on one occasion which left Mourinho shaking his head.
Missed an outrageous number of chances to bring his side back level and seems to have no confidence in his game.
J. Obi Mikel
Did nothing particularly remarkable or terrible before he was replaced by Schurrle on 66 minutes - the substitution which changed the game.
More creative than he has been in recent weeks but his finishing was frustratingly wayward.
Too hesitant in front of goal but finally managed to score when Schurrle presented a chance on a plate for him. Did not celebrate, suggesting he has either played his last game for Chelsea or is lining up a summer move to Cardiff. Perhaps both.
