Spilled a low Lampard free kick but did well to keep out the follow-up. Could not do much about Lampard's efforts in the second half, mind.
Solid at the back in the first half, particularly against Mata's early teasing crosses. Struggled a bit as Chelsea came forward late in the piece.
Some timely interceptions as the home side tried to play the ball inside him.
Booked early on for coming through the back of Mata. Good in the air against Ba in opening exchanges, looked accomplished alongside Vlaar.
Nearly forced Villa's second when his cross deflected off Cole, and that was following a bustling run down the right, but those occasions were all too rare on the day. Lucky to not be booked for tripping Hazard, but then did well to deny him at the death.
Tidy performance at the back of the midfield, covering a lot of ground and using the ball well, as he often does. Scrambled well to block Ba's shot on the line (or perhaps not) as Chelsea forced the issue.
Played in Benteke for the first, and was economical with his passing. Just about blocked Cahill's header on the line to force an incredible scramble.
Battling performance in the middle and flashed an effort agonisingly close to the top corner just after Villa went a goal up.
Worried the visiting defence with his pace, as he so often does. Offered very little else, though, especially on his left foot.
Has a tendency to drift in and out of games, and the first half was more of an 'out' performance.
Scored a brilliant goal, skinning Cahill and giving Cech the eyes to roll home at the near post. Very lucky not to have been sent off for an elbow on Azpilicueta, but did see red after the break for a high foot on Terry. Had the beating of Chelsea's central defenders all afternoon before that.
Beaten far too easily for Benteke's opening goal, but had little else to do after that despite the hosts' dominance.
A pretty subdued display from the left-back, who almost turned Lichaj's cross into his own net in the second half.
Got an elbow in the face in what was his biggest contribution to the first half. Did not do too much after the break, either.
Was at pains to get in position when faced with Benteke in full flight, only to be skinned all ends up as the Belgian opened the scoring. Looked worried by Agbonlahor's pace, but is not the first and will not be the last.
Could and possibly should have been sent off in the first half for two bookable offences, but the second went unpunished. Roundly booed for his role in getting Benteke sent off, which was getting kicked in the chest. Otherwise, looked slow and worried by the Belgian striker. Went off injured.
Tested Guzan with a low free kick in the first half, and put in more tackles than telling passes or shots until he drew the sides level with a left-footed strike to equal Bobby Tambling's Chelsea goalscoring record. He then beat the record from close range to all but wrap up Champions League football for the Blues.
Played several tantalising crosses into the Villa area in the first half an hour but the home defence managed to head them away each time. Did not perform to his usual high standards, which is unsurprising given the amount of games he has played.
Struggled to influence proceedings down the right, and his attempts to get in behind the defence proved fruitless in the first 45 minutes.
Booked for a cynical foul on Benteke, who had just scored the opener. Got away with a trip on Agbonlahor but was sent off on the stroke of half-time for a high foot. Was playing well other than that, and looked like he might be able to create something from deep.
Struggled to make an impact down the left before half-time, but proved the telling influence as he got to the byline to cut back for Lampard to score the winner. Hobbled off in injury time.
Missed a couple of good chances early on, though he was flagged offside for the first.
Came on for stricken Terry and did a solid job, especially in late, late onslaught.
Came on at half-time to sit in front of the defence in place of the departed Ramires. Did a superb job, cutting out numerous through balls and building attacks from deep.
Came on for the wasteful Ba, but did very little.
