The boss' verdict
Klopp explains that Coutinho's withdrawal at half-time was a planned one.
Klopp: "We are still a good football team, I still see it, but unfortunately it doesn't feel it at the moment."
Jurgen Klopp: "We were the better side in the first half but as long as we concede goals like we did today it's quite difficult."
Stats all, folks

Klavan goes in a touch too heavy on Okazaki and earns himself a yellow.
Gini Wijnaldum's evening is over as he makes way for Danny Ings.
Woodburn receives the ball on the left-hand side of the box and cuts in on his right for a curler...
Close! The youngster's attempt just nestles on the roof of the net. Really unlucky.
Leicester City 1-0 Liverpool (Okazaki)
The Foxes keep the ball alive after a corner and after some head tennis in the Liverpool box Okazaki is on hand to divert it home.
Ward can count himself unfortunate there - a big deflection having taken the ball out of his reach.
Grujic loses the ball and puts in a late sliding challenge on Ndidi in trying to make up for his error.
The referee isn't impressed and brandishes a yellow card.

A change for Leicester as Okazaki replaces Ulloa.
A hectic start to the second period as Gray sends a dangerous free-kick just over the bar and Liverpool win three corners on the bounce.

Thankfully, the Dutchman is fine to continue.
We're back under way in Leicester.
Ben Woodburn is, indeed, coming on.

Take a statistical look at that first half with our Opta widget below.
Leicester City 0-0 Liverpool
The Reds have utterly dominated the first half at the King Power Stadium but they have nothing to show for it.
Klopp will want to see that pressure turned into goals after the break.
Solanke sidefoots one onto the roof of the net as the fourth official indicates one minute of added time.
Some dangerous crosses have come in from this man's wing so far tonight.

Another raid in behind wins a corner but, again, the Foxes get it away.

Coutinho comes within inches of doing so but falls just short.
Solanke stretches to meet a powerful Robertson cross but he can only divert the ball over the bar.
The young striker did well to get there.
Danny Ward rolls one out to his defence.
Liverpool break quickly through Wijnaldum and the ball eventually filters out to Oxlade-Chamberlain on the right-hand side of the box.
Unfortunately, the No.21's cross is high, wide and handsome and Leicester are let off the hook.
Albrighton goes in late on Coutinho... but it's just a talking-to from the referee.
Danny Ward races out of his area to pinch the ball ahead of a fast-advancing Leicester attacker.
The Travelling Kop voices its appreciation, singing the Welshman's name to the tune of 'Daddy Cool'.

The former with a side-footed effort after a pull-back that is well blocked, his teammate with a low attempt that skims across the face of goal.
An early corner to Leicester is lofted to the back post where Grujic just about does enough to clear the ball for another corner.
This time, Ward rises highest to claim.
Gini Wijnaldum gets the game under way!

Here are the 90-minute match prices from BetVictor - more details here.
Leicester - 29/10
Draw - 29/10
Liverpool - 10/11
Liverpool and Leicester have only ever met once before in the League Cup - that came back in October 1986 at Anfield.
And the Reds ran out 4-1 winners that evening courtesy of a Steve McMahon hat-trick and an effort from Kenny Dalglish.
Will tonight’s result impact Saturday’s league game?
Leicester boss Craig Shakespeare ponders that very question in his programme notes this evening.
“How often do we see cup draws that pit two teams against each other just days away from another scheduled meeting in the league? It’s pure chance of course, but it does seem to happen a lot! I’m not sure whether it will make much difference to either club, though. We’ll make changes tonight to give game time to some members of the squad that need it and I expect Liverpool will do the same, so I’m not sure tonight will have much bearing on Saturday.”
The stage is set...
...and the sun is shining at the King Power Stadium.
