I have never heard it like this here before. Not only have the players been up for it, the fans have been excellent.
It's a celebration here at Stamford Bridge tonight.
Chelsea 3-0 Middlesbrough
The Chelsea fans are all out of their seats to give their appreciation to manager Antonio Conte. He reciprocates with vigor.
On the pitch, Patrick Bamford has been booked for a tackle near the byeline.
The resulting free-kick comes to nothing.
Chelsea 3-0 Middlesbrough
Middlesbrough make some headway up the left flank before being stopped in their tracks.
They try down the right now but it's blocked off there, too.
Chelsea regain possession. Boro are trying but are getting nowhere fast.

Chelsea make their final substitution and the crowd love it.
David Luiz comes off for soon-to-be-ex-Chelsea club captain John Terry.
This guy is going to be buzzing...

Nathaniel Chalobah is coming on for Pedro, which is a blow for me as it takes longer to type.
Middlesbrough make their final change, too. Alvaro Negredo makes way for Rudy Gestede.

Fantastic save. A really good strike from Moses but that was a wonderful save from Guzan.
Chelsea 3-0 Middlesbrough
Brad Guzan's gappy legs have been up for discussion tonight but they've just done a wonderful job of saving from Victor Moses.

Richard Mark Bradley: 3-0 down. Going down. Second best all over the park. Still all you can hear are the Boro fans singing. We deserve better.

Middlesbrough are having a nice passage of play here.
Bamford links up with Negredo but then he gives the ball away and Chelsea march forward again.
Willian feeds Fabregas, who is given a free run to pass to Pedro, who shoots over the bar.

G?T: When does the pub shut?
What The Guzan's Legs?
That's the one.
Open all night.
Poor Brad...
Chelsea 3-0 Middlesbrough
Diego Costa and Brad Guzan have clashed knees and both look in quite a lot of pain.
But they're staying on for now. Instead, Chelsea take off Eden Hazard and bring on Willian.

Wake up, Thibaut Courtois! You've got a job to do!
The Chelsea keeper finally gets to see some action with a Grant Leadbitter drive.
It's an easy save, mind.

Really patient. It's a lovely 1-2. A really good finish, a well worked goal and no less than this performance deserves tonight.
It's been a difficult night for Middlesbrough but Chelsea have been too good.
Chelsea 3-0 Middlesbrough
Cesc Fabregas (again) with a sensational flick-on to Nemanja Matic who, from close range, chests the ball down and slots home through Guzan's legs (again).
Majestic.
Nemanja Matic (64 mins)
Game over.

Hazard is so brave when he is flying through players like that. He almost encourages the opposition to put in those big aggressive challenges and is willing to put himself in that danger.
Fabio had no choice but to put in that challenge and it's because of Hazard's bravery.
