A very simple and much-needed win for Chelsea, who never got out of second gear. Villa were woeful. They are in trouble.
- Chelsea: Begovic, Azpilicueta, Terry, Zouma, Baba, Loftus-Cheek, Fabregas, Ramires, Willian, Pedro, Costa.
- Aston Villa: Guzan, Hutton, Richards, Lescott, Richardson, Gana, Westwood, Grealish, Ayew, Gil, Gestede.
Chelsea change. Loic Remy on for Willian.
Diego Costa nearly has the final word but Brad Guzan just nips in ahead of him to palm away Ramires' cross.
Before that, Costa ran into the back of Ashley Westwood, sparking another little tussle. He just can't stay away from bother can he?
Four minutes added.
This game was done and dusted a long time ago. Villa are resigned to their fate, Chelsea are seemingly happy with 2-0. Let's just get these last few minutes rattled off and get on home.
Eden Hazard gets a little cameo, coming on for Pedro, who has been quiet this half.
Diego Costa does a superb job for his team, holding the ball up and winning a free-kick off Micah Richards, who gets in a tangle with the striker and chests him down.
It looks like there was a flailing arm from Costa that caught the Villa man. I wouldn't be confident to say it was intentional, though. But this is Costa and his reputation follows him.
Finally, some singing from the home fans. It is only a brief rendition of a song but it shows there is still life out there.
The home team greet the rise in noise by creating a great chance as Willian's pass finds Cesc Fabregas is space in the box for a shot that flashes a yard past the post.
Chelsea are heading for victory here but you wouldn't know it. The stadium is very quiet.
Willian is booked for tripping a Villa player just inside the Chelsea half.
Good work from Chelsea denies Joleon Lescott as a number of bodies throw themselves in front of the ball as it drops at the defenders feet following a free-kick into the box. The Blues have not had to defend much this half but they did that superbly.
It could have been three. Villa gift the ball to Willian again but this time, unlike the opening goal, Diego Costa cannot finish a low cross with Brad Guzan diving out to claim.
Watching this, you fear for Villa this season.
This definitely won't do for Villa, who make another change. Jordan Ayew departs and Adama Traore is introduced.
This won't do for Villa, though. They make their first change as Jordan Amavi comes on for Kieran Richardson.
There was a time when Chelsea would have gone for the jugular in these circumstances. The Blues are not in that place right now, though. 2-0 will do just fine for Jose Mourinho's men.
Villa look done. Pedro is found on the right corner of the box in acres of space, but his shot flies past the far post.
Soon after, Cesc Fabregas' cross is met by the head of Diego Costa in the box but not with the power to test Brad Guzan.

"Aston Villa have been very clumsy and careless, and Guzan has done them no favours. Frankly, from a good first half hour it has all fallen apart."
That could well be that. Cesc Fabregas picks up the ball and floats a pass into the box for Diego Costa, who brings the ball down with his chest turns well and then fires a low shot that wasn't destined for the goal until the heel of Alan Hutton deflects the ball past Brad Guzan.
Long way back for Villa now.
The first card goes to the Villa man as he slides in to the back of Ramires near the touchline.
Jack Grealish with an effort for Villa - the first of the half - which flies past the far post.
Chelsea make a change at the break as Nemanja Matic comes on for Ruben Loftus-Cheek. Apparently this is tactical. It's a shame as the youngster did quite well.
Hopefully, Matic will last longer than 15 minutes this time.
Joleon Lescott is number 16 on this goal map. His marker is black and yellow but it should probably be bright red from the embarrassment of allowing Willian to nick the ball and Costa to score.
That is your lot for this half. Hardly a classic but Chelsea have the lead and in their current predicament that is all they will care about. Villa are seemingly on a suicide mission with the amount of times they have given the ball away.
Stamford Bridge is eerily quiet. Maybe a hot brew at the break will liven them up?
Guess what? Villa give the ball away again in their own half but Ruben Loftus-Cheek can't latch on to Diego Costa's pass into the box.
One minute of time is added to the half.
What are Villa doing? Again, their defence gift the ball to Diego Costa, who drives in to the box but is muscled out by a combination of Joleon Lescott and Kieran Richardson. The striker drops to the floor looking for a penalty but the referee isn't fooled.
Villa can't just sit back now. They have to create something. Ashley Westwood almost does with a deflected shot from the edge of the box that Asmir Begovic saves.
Jack Grealish then gets top the byeline but can only drive his low cross into the hands of the Chelsea keeper.

"I don't know what Brad Guzan was doing. You have to clear your lines. Any mistake and Chelsea will pounce on it, even with the poor run of form they're on at the moment.
"Villa had a chance five minutes before where Rudy Gestede should have scored. They didn't and now they've been punished."

"This is a great test of Tim Sherwood's managerial ability. At half-time will he rant and rave? Before conceding, his team was doing very well and was unlucky not to be in front. What does conceding that goal do to morale?"
Villa are losing their discipline. Micah Richards knocks down Pedro for a free-kick on the left of the box. Willian curls it in to the box but also straight into the hands of Brad Guzan.

"Jose Mourinho couldn't afford to take Terry and Ivanovic out of the team at the same time. Those two players, who may both be lacking pace, contribute in other areas. Mourinho is having the manage a team that's getting old."
A goal, gift-wrapped by Villa and gratefully received by the majority in Stamford Bridge. For the third time, Villa give the ball away in a dangerous area as Brad Guzan's pass is not controlled by Joleon Lescott and stolen by Willian, who drives in to the box before setting up Costa for an easy finish.
It is a huge lift for Chelsea, who have been average and a massive blow for Villa, who have looked pretty comfortable.
Oh, great chance for Villa's Rudy Gestede. Probably the best of the first half. Jordan Ayew gets past his man on the left and crosses low into the box, where Gestede gets ahead of the hesitant John Terry but flicks his effort just over the bar.
Terry responds at the other end with a header from a free-kick which loops over the bar. Just a flicker of life in this match.
Willian does take it, but only to set up Kurt Zouma for a low shot that hammers into the wall before being cleared.
Plenty to ponder for Jose Mourinho. He sits forward on his seat as Cesar Azpilicueta wins a corner. Once again, though, it comes to nothing.
However, Chelsea then win a free-kick about 25 yards from goal. Willian. Calling Willian...
The ball is pinging around in the a congested middle third with little sign of control from either side. It's messy stuff. Messy and directionless. It suits Villa.
Nice play from Villa allows Kieran Richardson to charge away down the left but his cross is unable to be brought down by Rudy Gestede before Chelsea hammer it away.
Soon after, Jack Grealish wins a free-kick on the edge of the box after being blocked by Cesar Aspilicueta. Jordan Ayew has a pop and gets it over the wall but also the bar.
It is quite flat at the moment. Villa are happy to contain and Chelsea are struggling to move the ball at the required speed to hurt the visitors.
