Rarely tested thanks to some wayward finishing from the visitors, and could do litttle about Holt's strike.
Composed as ever on the ball, but was occasionally guilty of granting Holt too much space.
Got forward well to provide width for his team in attack and his cross to set up Torres' goal was pinpoint, but he was caught out far too often defensively, allowing Norwich to cross almost at will. Took his goal superbly though.
His usual reliable self in terms of an attacking outlet, but fared little better than Ivanovic at protecting his centre-backs from the visitors' aerial bombardment.
His ability to block out any off-the-field controversies is now the stuff of legend. This was a semi-assured display, although Holt enjoyed a worrying amount of success against him in the duo's aerial duels.
The least influential of Chelsea's midfield trident, but there were still a few moments of brilliance without an end product.
Used the ball intelligently and efficiently, releasing Chelsea's creative wizards at the right time, and even popped up in the box to score a trademark goal before his withdrawal with just over 20 minutes left.
J. Obi Mikel
A disciplined and thankfully restrained display. His shielding of the back four was such that most of Norwich's success came down the flanks.
After a slight lull by his own extremely high standards, this was a return to the kind of form which had fans and neutrals alike purring. His movement and vision were constantly in evidence, and his sublime link-up play with Mata deserved to yield more than one excellent goal.
Once again the conductor of the Chelsea orchestra. His genius enabled three of his side's four goals and he was at the centre of everything the home side did well.
A performance which added to his goal tally and his enigma. Inexplicably fluffed a golden chance early on, but redeemed himself with a well-taken header. His wavering first touch still mystifies and, as long as he performs like this, the Falcao talk will not go away.
Helpless to prevent any of Chelsea's goals and was given precious little protection by a defence shorn of confidence.
Inexplicably found himself in a position to tee up Holt for Norwich's shock opener, but his defensive positioning was woeful and his attempts to repair the damage clumsy all afternoon.
Delivered a couple of dangerous crosses for Holt, but granted Ivanovic too much space to swing in a decisive cross for Torres.
Tried his best to marshall a faltering backline, but he must regard having Barnett as his partner as some sort of divine punishment.
Tormented by Hazard, Mata and Oscar throughout, he could be having nightmares about this game for some time.
Carried a threat on the break down the right flank, but left Martin hopelessly exposed to Hazard, Mata and Oscar.
One wayward shot from 25 yards aside, Chelsea's midfielders gave him a torrid afternoon.
Like Johnson helpless to stop the hosts getting at his team's fragile defence, he was at least industrious.
Put in a good cross which led to Norwich's opener but, in general, his influence was minimal.
Outclassed and out-passed by the Chelsea midfield, he deserves credit for remaining determined to bring his side up the pitch whenever he could.
Did not deserve to be on the losing side. Took his goal superbly, took the fight to the Chelsea defence whenever he could and acquitted himself superbly in the face of overwhelming odds.
Replaced Ivanovic with 12 minutes to go and delivered a solid cameo.
Played the final eight minutes in place of Mikel and was unlucky not to get on the scoresheet.
Replaced Lampard with just over 20 minutes left and provided some much-needed energy as his side saw the game out comfortably.
Replaced Bassong in defence with 12 minutes left when Chelsea seemed content to take their four goals to the bank.
Replaced Johnson in the middle of midfield with 20 minutes left and became another body in Norwich's massed ranks.
Replaced Holt with 13 minutes left but was nowhere near as effective as the man he replaced.
