Leicester City 2-4 Chelsea: EFL Cup third round - as it happened

That is all for this live blog, but be sure to check in with IBTimes UK sports editor Nick Howson tomorrow night as he brings you live coverage of the remaining eight EFL Cup third-round fixtures including Northampton vs Manchester United, Tottenham vs Gillingham and Swansea vs Manchester City.

He will also bring you the draw for the fourth round as it happens.

Goodbye for now.

So five-time winners Chelsea seal their place in round four after a thoroughly entertaining encounter. Conte will be pleased with the character and resilience shown by his side, but some of their defensive lapses in that first half will give the Italian cause for real concern.

They have the small matter of a Premier League trip to Arsenal on Saturday, while Leicester visit Manchester United. The Foxes also resume their Champions League campaign next week as Portuguese giants FC Porto travel to the East Midlands.

Full-time

Leicester 2-4 Chelsea

Chalobah sends Fabregas clear with a well-weighted pass, but the Spaniard is rightly flagged for offside.

Ulloa goes down holding his calf after a robust aerial challenge from Cahill. Neither side has a substitution remaining and the striker will have to soldier on regardless.

Alonso's cross from the left is too pacey for Fabregas and his rogue touch sends the ball high and wide. Chelsea are cruising towards the finish line.

Luiz is the latest player to be carded for bringing down Vardy. Leicester are handed a free-kick in a dangerous position on the right-hand side but it is overhit and wasted by Drinkwater.

The second half of extra-time is upon us. Any comeback from Leicester now, considering their numerical disadvantage, would be truly miraculous.

It's at times like this that one really misses Golden or even Silver Goal. Fabregas' emphatic double has ended this as a contest but we still need to play the final 15 minutes.

Half-time in extra-time

Leicester 2-4 Chelsea

Evidently undeterred by fatigue, Moses races to the byline but his attempted cross lacks accuracy and is scooped up by a grateful Zieler.

Chilwell is then rightly cautioned for a reckless late sliding challenge on Azpilicueta.

Things probably should have gotten worse for The Foxes, but Costa fails to gamble in the six-yard box and Azpilicueta's perfect low cross is wasted.

Leicester look out on their feet now as Zieler has to get down low to tip a shot from Matic around the post. Hazard and Costa, as you might expect, have made all the difference for Chelsea.

An emphatic start to extra-time from Chelsea, who strike twice in quick succession to surely put this third-round tie beyond 10-man Leicester.

Fabregas has grabbed both goals, smashing in after a smart backheel from Hazard before firing home again after Leicester had failed to clear their lines.

Game over?

Goal: Leicester 2-4 Chelsea (Cesc Fabregas)

Goal: Leicester 2-3 Chelsea (Cesc Fabregas)

The first period of extra-time is underway. Will this tie be settled in 30 minutes, or is a penalty shootout on the horizon?

We are heading for extra-time in the East Midlands.

End of 90 minutes

Leicester 2-2 Chelsea

Chelsea are going hell for leather in search of a winning goal. First Moses fizzes an excellent effort wide and now Costa bursts through before hitting the side netting.

Breathless stuff at the King Power.

Having just seen Hazard come on for Pedro, the last thing Leicester needed was to go down to 10 men with the prospect of an extra 30 minutes looming.

Wasilewski, who has looked miles off the pace tonight, picks up a second yellow card for a foolish challenge on Costa.

Gray makes way for Amartey. Four minutes of added time signalled.

Red card: Marcin Wasilewski (Leicester)

Almost a late chance for Leicester as Gray tricks his way towards the byline but rolls a low pass just too far behind Schlupp.

We are heading for extra-time, unless one of these sides can find a late winner. They are certainly both going for it.

Costa is becoming a real thorn in Leicester's side as the clock ticks down towards the end of 90 minutes.

After getting in between the centre-backs to fire a pass from Azpilicueta at Zieler, the fiery striker collects another Luiz long ball special and proceeds to bamboozle both Wasilewski and Chilwell.

His first drive is saved by the legs of Zieler, who gets back up to deny the follow-up shot from a tight angle.

Typically determined play from Vardy has he pressures Begovic from the off and forces the goalkeeper into a nervous error.

Chelsea survive another corner before changing shape again by throwing on Nathaniel Chalobah for Batshuayi. Unbelievably, this is the 21-year-old's first senior appearance for the club.

Leicester's second change sees Vardy replace Musa. Just moments ago, the latter made a mockery of Chelsea's centre-back pairing by outmuscling Luiz and racing past the plodding Cahill onto a long ball from Zieler.

Fortunately for the visitors, Begovic was able to divert his shot wide.

Ranieri sends on Leonardo Ulloa in place of two-goal Okazaki. The Argentine's first contribution is to guide a corner towards King, who inexplicably heads over from point-blank range. Incredible miss.

How have Chelsea not taken the lead?! Luiz causes a static Wasilewski all sorts of problems with another sweeping long pass. Costa collects and looks certain to score but winds up putting his shot agonisingly wide.

What a save by Zieler to keep Leicester level. Batshuayi collects Costa's knockdown and takes a lovely touch before firing a vicious left-footed shot that is acrobatically tipped over the crossbar.

Pedro's shot is blocked by Wasilewski and Alonso hits the rebound well wide. Costa comes on for Loftus-Cheek.

He will look to form a potent partnership with Batshuayi in the final third.

A couple of long balls forward from Chelsea fail to reach their intended targets. Simpson then angrily tells Pedro exactly what he thinks of his somewhat laboured attempts to win a free-kick.

King stands up Cahill before knocking the ball inside for Gray, who falls after a tangle of legs with Azpilicueta. Again Leicester want a penalty but referee Madley is having none of it and penalises the winger for handball.

Right decision.

Schlupp goes close with another winding shot and Loftus-Cheek heads Fabregas' free-kick harmlessly over the crossbar.

Wasilewski also picks up a yellow card for a foul on the England U21 midfielder.

The away end erupts as Chelsea draw level with less than five minutes gone in the second half. And what a goal it is from an unlikely source.

After a sustained attack, Wasilewski's clearing header travels only as far as Azpilicueta. The Spanish full-back, known for versatility and a dependable nature rather than his goalscoring exploits, thunders an unstoppable right-footed volley past Zieler.

Stunning.

Goal: Leicester 2-2 Chelsea (Cesar Azpilicueta)

Leicester almost extend their lead as Schlupp picks up Chilwell's headed knockdown from a long Danny Drinkwater free-kick. He is given too much space by Cahill and Fabregas but can only shoot into the side netting.

That was a let-off for Chelsea.

The second half is off and running. Chelsea are straight on the front foot as Moses makes headway down the right and feeds Pedro, whose goal-bound shot is saved by Zieler.

So a lifeline for Chelsea at the break. Defensively they have been appalling without Terry so far this evening and that midfield system is simply not working at all.

Ranieri will be annoyed that his captain suffered a momentary lapse in concentration by allowing Cahill to get loose for that late goal. Okazaki is a constant menace and Leicester will hope that they can have some joy on the counter as the visitors push for an equaliser.

Half-time

Leicester 2-1 Chelsea

Chelsea hit back on the stroke of half-time. Cahill has not played well defensively tonight, but he makes his presence count in the opposition box by getting away from Morgan at the back post and heading Fabregas' corner beyond Zieler.

Luiz made sure it was over the line, but that's Cahill's goal.

Goal: Leicester 2-1 Chelsea (Gary Cahill)

Okazaki just fails to tee up Musa. At the other end, Wasilewski stays tight to Batshuayi and deflects his low strike over the crossbar.

Another warning shot for Chelsea. This time Gray receives possession from Schlupp and cuts inside before firing wide of Begovic's left-hand post.

Loftus-Cheek tries his luck from the edge of the box but Zieler is equal to the shot. Batshuayi then drills in an excellent strike from distance, but he had already long since been penalised for handball.

Begovic also comes off his line to thwart the run of Musa.

Okazaki hadn't scored for Leicester since March, but he has two inside the first half here.

It's more useless defending from Chelsea as the Japanese international is put through by King and, under pressure from Luiz, he drives a shot into the ground and over Begovic.

Azpilicueta attempts another last-ditch clearance but again he is far too late to stop the ball going over the line.

Goal: Leicester 2-0 Chelsea (Shinji Okazaki)

Loftus-Cheek shows good persistence to burrow into the penalty area and win a corner from Chilwell. Leicester clear their lines twice before a good ball towards Pedro is tamely volleyed into the hands of Zieler.

Batshuayi initially does well to exploit a sizable gap between Wes Morgan and Chilwell. Pedro provides the ammunition for a free header, but the Belgian striker can only head well wide.

He should have done much better with that.

Chelsea try to respond quickly but Pedro is unable to capitalise on a neat pass from Fabregas. They also had a corner before going behind, but the delivery sailed far over Luiz's head.

Despite being second best during the early stages of this contest, Leicester edge ahead with less than 20 minutes gone.

It's nothing short of calamitous defending from Chelsea as Alonso gives the ball away and Musa's subsequent searching cross evades everyone before being chested back across goal by Azpilicueta.

That risky touch allows an opportunistic Okazaki to steal in and lift a close-range header over Begovic. Azpilicueta tries to hook it away, but the linesman signals for a goal. That was comfortably over the line.

Conte will be furious with that comedy of errors.

Goal: Leicester 1-0 Chelsea (Shinji Okazaki)

Nervy moments for Cahill as he sloppily concedes possession to Okazaki in a dangerous area thanks to a woeful touch. Musa seizes on the loose ball, but he is held up by Luiz before seemingly being shoved to the ground by Cahill.

Leicester scream for a penalty, but Madley shakes his head. Controversial.

Chelsea have been much the better side in this opening 10 minutes. Zieler is forced to beat away a dangerous cross from Pedro and Wasilewski is perhaps fortunate not to be penalised for a needless handball as he tries to clear under pressure from Batshuayi.

Almost another opening for Chelsea as Nemanja Matic passes to Pedro, who releases debutant Alonso on the overlap.

The Spaniard's low, first-time cross narrowly evades Batshuayi and Zieler can collect.

Goa..no! Luiz plays a sweeping ball forward that Pedro, in behind a sleeping Danny Simpson, collects before firing into the back of the net with aplomb.

However, his joy proves to be shortlived as the referee's assistant raises an offside flag. That looked a really tight decision at first glance.

Chelsea look to make an immediate impact as Batshuayi finds Moses, who drags a speculative long-range shot well wide. That was never likely to trouble Zieler.

Referee Bobby Madley blows his whistle and we are underway in the East Midlands.

Leicester, sporting their usual all-blue home strips, are kicking from left to right. Chelsea are wearing their black and grey hooped changed shirts with fluorescent trim.

A good omen for the visitors, perhaps....

Chelsea to revert back from their 4-1-4-1 formation to a bold 4-2-4 system tonight?

Due to their involvement in the Champions League, Leicester were handed a bye into the third round of this year's League Cup.

Owing to their disastrous mid-table finish last term, however, Chelsea have no European obligations in 2016/17 and were drawn against League One outfit Bristol Rovers in round two. That tie proved to be less than straightforward, although Conte's side did eventually prevail 3-2 at Stamford Bridge thanks to Batshuayi's brace and a goal from Moses.

Both of these sides reached round four last season before being knocked out by Hull and Stoke respectively.

Despite a summer transfer window in which they were constantly frustrated in their pursuit of new defenders, Chelsea looked to be settling into life under strict, flamboyant tactician Conte rather seamlessly courtesy of successive wins over West Ham, Watford and Burnley.

However, their momentum has stalled somewhat over the past nine days with dropped points at Swansea and a demoralising home defeat to Liverpool. The Blues will hope for a swift return to form with a trip to Arsenal looming on Saturday.

So how have these two sides started the 2016/17 campaign?

For Leicester, surely nothing can ever top last season's incredible, fairytale, 5,000-1 title win, although fans certainly enjoyed making their Champions League debut with an emphatic win in Bruges last week.

Their domestic form has been inevitably more erratic, with Community Shield disappointment against Manchester United and a shock opening day defeat at newly-promoted crisis club Hull followed by a goalless draw with Arsenal a narrow win over Swansea.

They returned from the international break with a heavy 4-1 defeat at Liverpool before consecutive 3-0 wins over Club Brugge and Burnley.

Conte keeps tireless midfielder N'Golo Kante on the bench for his first return to the King Power Stadium since completing a £30m move to Chelsea in July.

Second-choice goalkeeper Asmir Begovic replaces Thibaut Courtois and £23m deadline day signing Marcos Alonso makes his debut at left-back. Cesar Azpilicueta shifts to the opposite flank, with Branislav Ivanovic dropping out altogether. Injuries to Zouma and Terry mean that Gary Cahill and David Luiz continue their unconvincing partnership in the centre of defence.

Fabregas does indeed start instead of Kante, while Victor Moses, Ruben Loftus-Cheek and Pedro are given the nod instead of Willian, Oscar and Eden Hazard. Batshuayi starts in place of Diego Costa.

As promised, Ranieri makes seven changes to his Leicester XI. In defence, Marcin Wasilewski and Ben Chilwell replace Robert Huth and Christian Fuchs. Demarai Gray, Andy King and Jeff Schlupp also come in for Marc Albrighton, Daniel Amartey and Riyad Mahrez.

Talisman Jamie Vardy and record signing Islam Slimani, who netted twice against Burnley, also make way for Shinji Okazaki and Ahmed Musa.

Chelsea: Begovic, Azpilicueta, Cahill (c), Luiz, Alonso, Moses, Fabregas, Matic, Pedro, Loftus-Cheek, Batshuayi

Subs: Courtois, Aina, Chalobah, Kante, Willian, Hazard, Costa

Leicester: Zieler, Simpson, Wasilewski, Morgan (c), Chilwell, Gray, Drinkwater, King, Schlupp, Okazaki, Musa

Subs: Hamer, Benalouane, Amartey, Mahrez, Kapustka, Vardy, Ulloa

The line-ups are in....

As for Chelsea, long-serving captain John Terry is back in training following his own ankle injury but will not be considered for this tie. Kurt Zouma and Marco van Ginkel remain long-term absentees.

Like Ranieri, Conte will likely make a number of personnel changes tonight to utilise all areas of his squad. Michy Batshuayi, Cesc Fabregas and Pedro are among the players expected to be upgraded.

Let's discuss the latest injury news while we await word on tonight's official teamsheets.

Leicester boss Claudio Ranieri, who spent four years in charge of Chelsea between 2000-04, confirmed in his pre-match press conference that Ron-Robert Zieler will continue in goal after deputising for Kasper Schmeichel and keeping a clean sheet during the 3-0 win over newly-promoted Burnley on Saturday. The latter is expected to be fit for this weekend's trip to Manchester United after a concussion, however.

Elsewhere, midfielder Nampalys Mendy is not yet ready to return from an ankle injury sustained during the goalless draw with Arsenal one month ago. Matty James also remains out, while Ranieri is expected to make several changes to his usual starting XI.
