Anon: Fair play to the Middleborough fans, not many would still be singing! As I said that they just scored! What a goal!
James: You'd think Middlesbrough were winning and at home from the noise their fans are making!

Morgan Rogers is nearly in again but Alfie Gilchrist does well to get across, use his strength and force the Boro forward away from goal.

They have been good, they have been clinical and professional.
I think the club probably needs this after what they have been through for the last 18 months. It's not what they wanted, but it is the start of a new era for this football club.

Three minutes of added time to be played.
Chelsea are heading to Wembley but they're being drowned out by the Middlesbrough fans at the moment.

They have not given up. The fans deserve that after coming down from Middlesbrough and I think that is probably the goal of the evening.
That might be the only one of the evening for Middlesbrough but that is definitely the goal of the night.

James: Aren't Boro fans amazing? Biggest game they have this season, losing 6-1 and singing their hearts out while smiling. Really cool to see.
Morgan Rogers
A consolation but that is a brilliant goal!
Morgan Rogers has plenty of time and space to advance to the edge of the Chelsea box and then uses the defender as a shield to bend the ball into the bottom corner.
Super finish and the Middlesbrough fans, who haven't stopped signing all night, have something to celebrate.

This is a record-breaking performance from Chelsea.
They have currently got the largest winning margin in the second leg of a League Cup semi-final, beating Liverpool's 5-0 thrashing of Crystal Palace in 2001.

Great to get into the final but can we maintain this energy against PL opposition, most likely recent-ish PL and CL champions?

Chelsea make another sub and it is a debut for 19-year-old Leo Castledine.
He replaces Raheem Sterling.

It's actually a fantastic header.
Unfortunately, it wasn't to be.
I love that they aren't letting anything get them down and the fans are still making loads of noise in that away end.

Middlesbrough do have the ball in the back of the net thanks to a lovely flicked header from Matt Crooks.
Unfortunately for them, he was just offside.

The Middlesbrough supporters are still making a lot of noise and backing their team even though they're 6-0 down.
Noni Madueke
Forget five-star, Chelsea have got six of the best...
Noni Madueke gets into the box down the right channel, cuts back inside onto his left foot and beats Tom Glover.
The shot was heading into the far corner of the net but Rav van den Berg gets a big boot on it to send it into the other corner.
Still the Chelsea man's goal.

That isn't an easy finish at all.
If that was on my right foot, it definitely wouldn't have ended up in the bottom corner.

It's a tap in. A right-footed one.
This time it is fed across by Conor Gallagher and he used the pace that is already on the ball.
Palmer keeps his cool to make it 5-0 to Chelsea.

Get ready for a few 'five-star Chelsea' headlines...
Conor Gallagher gets to the byeline down the left and cuts the ball back.
Cole Palmer is waiting and finishes clinically, first time into the far corner.

Middlesbrough are enticing that press and when their passing hasn't been great and their confidence has been knocked, I'm not so sure why they are doing it.
Chelsea keep winning the ball back and continue to create chances.
The disappointing thing for me with Middlesbrough is that they have made it a bit of a training game and let Thiago Silva and Levi Colwill do what they want with it.

Into the last 15 minutes of the 90 and Chelsea come forward again.
Noni Madueke gets to the byeline and cuts the ball back but Matt Clarke slides across to avert the danger at the expense of a corner.
Chelsea 4-0 Middlesbrough (Agg: 4-1)
Nearly another horror show for Middlesbrough as they try to play out from the back.
Goalkeeper Tom Glover is put under pressure, he plays the ball across his goal to Dael Fry just inside the six yard box and Raheem Sterling is waiting to pounce.
The Chelsea winger pinches it but Fry is able to block the goal-bound shot to avoid another calamity for the visitors.
