Just 12 minutes to go. Are we going to penalties? Carl Winchester hammers a shot over for Sunderland.
Chelsea 1-1 Southampton
Two more changes for Southampton - five can be made in this competition - as Ibrahima Diallo and Stuart Armstrong make way for Oriol Romeu and Will Smallbone, who makes his return after nine months out with injury.
It is an almost immediate impact from Smallbone but his header is denied by Kepa!
What a story that would have been!

It already seems like Leeds are gonna struggle this season. Such a bold team always trying to push forward but it might drop them this year.
Pete, evon
Arsenal 2-0 Leeds
They've already lost one centre-back this evening and now Rob Holding is down.
It looks like cramp.

Huge chance for Saul and he will be kicking himself. It is a beautiful left foot but he pulls it wide of the post.
Chelsea 1-1 Southampton
Big chance for Saul Niguez to get his first goal for Chelsea as he is picked out by a cutback on the edge of the area. He strikes first time but sidefoots just wide of the post.
Arsenal 2-0 Leeds
Couple of changes made by Leeds and two for Arsenal too.
Alexandre Lacazette and Albert Lakonga are on for Emile Smith Rowe and Mohamed Elneny.
Chelsea 1-1 Southampton
A reminder there is no extra time in the League Cup so this will go to penalties if needed.
Southampton have a free kick but Shane Long puts his header wide.
Arsenal 2-0 Leeds

The Leeds fans are complaining about something, I'm not sure what it is.
It's a header back that's miss-headed.
Nketiah just gets there first, touches it over the goalkeeper. His shot is from right on the edge of his foot, he very nearly missed it.
QPR 0-0 Sunderland
Both sides make changes.
QPR sub Charlie Austin - who replaces Andre Gray - shoots over with one of his first touches.
Sunderland bring on Aiden McGeady and Aiden O'Brien for Corry Evans and Lynden Gooch.
Eddie Nketiah
Tie over?
Eddie Nketiah tries his best to miss but manages to get it into the net.
The Arsenal frontman is quick to react to Liam Cooper's poor header which lacks power and fails to get anywhere near IIlan Meslier.
Nketiah collects the ball, goes round the goalkeeper and with a whole goal to aim at from a yard out, he shins a finish which creeps into the net. Just.
Lead doubled and a mountain to climb now for Leeds.
Arsenal 1-0 Leeds
Leeds looking to get back into the game, Jack Harrison's drive from outside the area stings the palms of Bernd Leno.
Chelsea 1-1 Southampton
A couple of changes for both sides with just under 25 minutes to go.
Hakim Ziyech and Ross Barkley - both quiet tonight - make way for Mason Mount and Ben Chilwell for the hosts.
Che Adams and Nathan Tella are off for Southampton with Shane Long and Theo Walcott on.

Jan: Maitland-Niles has been absolutely quality so far today in the middle. I didn't know he had it in him and that is with him coming up against Phillips too.

Arsenal might not get a better chance at a trophy this season.
Quarter-final after this game, it gets my attention as a player, you want to be involved in games like this for me.

We've seen lots of attacks from both teams' flanks but neither group of midfield players have got their foot on the ball, they've not won that battle in the middle. It has been really, really scrappy.
Arsenal 1-0 Leeds
Nicolas Pepe looking for Arsenal's second, drifting in from the right but his shot deflects off Stuart Dallas and lobs into the hands of Illan Meslier.
Arsenal 1-0 Leeds
Lovely move from Arsenal.
Ainsley Maitland-Niles fizzes a pass into Gabriel Martinelli and the Brazilian flicks it back beautifully.
AMN then spots the run of Eddie Nketiah in the box but the Arsenal frontman scuffs a shot from a narrow angle straight at Illan Meslier.
