Chris Sutton
Ex-Chelsea striker on BBC Radio 5 live

This is so big in Chelsea's season. So important to get over the line with all the pressure on Chelsea and Antonio Conte. He may be going but he must want a trophy.

Credit to Leicester for getting back into the game, but interesting to see how Chelsea the play in the next 30 mins.

Not sure why Chelsea didn't do that at the break.

Anyway Pedro has trotted on in place of Willian.

Maybe the Brazilian was trying to run off a tweak and it is not happening for him.

A quick sip of isotonic and we are back under way.

On Kasper Schmeichel's double save from Alvaro Morata: "Schmeichel took the space out very quickly from Morata and was quick enough to cover. As a keeper, you fear for the penalty but he didn't fully commit to not make contact. He did very well."

Former Newcastle striker on BBC One

An absolutely fair result after 90 minutes. Leicester were much much better in the second half, played further up the pitch and with more energy.

They didn't let Chelsea control the pace of the game - they deserve another bite at it.

Dad's Army/Ski Sunday/Antiques Roadshow will be delayed.

We have an extra 30 minutes of football - and possibly penalties - to decide this one.

Kasper Schmeichel comes haring out of his area to clear Cesc Fabregas' long ball forward with a first-time hip-high volley.

Casually done.

Three minutes extra.

Extra-time and penalties await remember. No replays nowadays.

It can go either way at the moment. Both teams have been on top in either half.

Victor Moses - who has not been overcareful with his elbows this afternoon - plants a joint into the mush of Marc Albrighton.

That is yellow.

And Marc Albrighton dabs some claret out of his airways before getting back involved.

Lee: Very good double save by Schmeichel!! Really good last ten minutes of this game.

Chance!

Alvaro Morata is played on the edge of the six-yard box, but with Kasper Schmeichel already in face and star-fishing, he has to take it first time.

His poked chance rebounds to safety off the goalkeeper's shins.

Alvaro Morata is sent sprawling as Harry Maguire slips and the Spaniard stumbles over the prone Leicester defender.

Chelsea remind the ref that Maguire has already been booked.

Craig Pawson thanks them for keeping him up to date and gives just a free-kick.

Paul: Game on now!!! For the neutral we want extra-time.

Scott: How many chances did that take to go in?! Caballero unlucky there but this tie is finally alive again.

Leicester have pushed and pushed in this second half and have their reward - now can they make their fresher legs count?

The home fans are sensing the complete comeback and there is a real buzz of anticipation inside The King Power Stadium.

It is great pace again from Jamie Vardy. It was good defending too. Cesar Azpilicueta narrowed the angle down.

Harry Maguire motors out of the Leicester defence like a 1998-era Sol Campbell.

The centre-back gets his head up and slips a lovely reverse ball into the path of Jamie Vardy.

The angle is against the striker, but he is buzzing with confidence and belts it anyway.

Willy Caballero has to be alert to keep it out.

Vince: Leicester are so much better when Okazaki plays

Tom: Jaime Vardy having a party

Lee: Great from Vardy and Mahrez!! Leicester fully deserve that!!

Phil Brown
Swindon Town manager on BBC Radio 5 live

I said this game was not over by any strech of the imagination.

Riyad Mahrez does well getting to the byeline and getting the ball. And Leicester manage to keep the box, keep trying and Vardy gets his goal.

I don't think this won't go to extra time, I think both teams will go for it.

Alvaro Morata rattles the post with a powerful tow-poke but the Chelsea striker is flagged offside as he pounces on a low cross.

This game is swinging now.
