Petr Cech 7 - Cech didn't have a great deal to do tonight and was beaten by a somewhat fortuitous strike from Fabian Delph, but made key saves from Christian Benteke and Delph again late on.
Branislav Ivanovic 7 - A feature of a few Chelsea attacks was Ivanovic overlapping down the right hand side, and that was important with the three attacking midfielders tucking in so much. The Serbian also had a solid game defensively but was caught out of position a couple of times.
Gary Cahill 6 - Cahill solid if unspectacular on his return to Villa Park tonight, as he struggled occasionally with the power and aerial ability of Villa striker Benteke.
John Terry 6 - Terry, much like his defensive partner, had some trouble with Benteke and looked slow on occasion, but Terry can't be blamed for Chelsea's capitulation in the second half.
Cesar Azpilicueta 8 - Azpilicueta continues to prove why Ashley Cole is on the fringes of the Chelsea team with yet another impressive display at full back, surging forward whenever possible but also coping with the threat of the overlapping Leandro Bacuna too.
Nemanja Matic 7 - Matic played his usual role in breaking up play, but after Chelsea went down to 10 men, Villa became relentless and the Serbian was guilty of giving away possession a number of times, as well as being beaten far too easily by Fabian Delph in the build-up to the winning goal.
Ramires 5 - Ramires was deservedly sent off late on for a shocking challenge on Karim El Ahmadi, but other than being able to run relentlessly, the Brazilian offered very little.
Willian 5 - Brazilian Willian has been a key player for Chelsea this season but failed to stamp his authority on the game tonight, and his game was ended early by a harsh red card for two bookings.
Oscar 6 - Unsurprisingly substituted after some poor decision making, which involved shooting rather than passing on a number of occasions, but how would the game have been different had Mourinho substituted Willian rather than Oscar, as he first intended.
Eden Hazard 7 - often Chelsea's only creative spark on an off-day for many Blues players, Hazard kept probing away at the Aston Villa defence despite little help around him, and was influential in most of Chelsea's attacks.
Fernando Torres 6 - Torres troubled the backline with his runs in behind on a number of occasions, particularly in the first half, but was either too ponderous in possession or made poor decisions, which stalled Chelsea attacks.
Andre Schurrle 6 - just second after the German was introduced, Willian was sent off and Chelsea instantly lost a grip on the game, meaning flair players like Schurrle didn't get much of a chance to make an impact, but a good run forward drew a dangerous free kick outside the box.
Demba Ba 5 - Chelsea went far more direct when Ba came on, but the Senegalese striker had little impact on the game, failing to latch on to many of the long balls aimed in his direction.
