Good evening and welcome to Sports Mole's live text coverage of the EFL Cup fourth round clash between Chelsea and Derby County at Stamford Bridge.
This match sees Chelsea's all-time leading scorer Frank Lampard return to Stamford Bridge for the first time as a manager, having seen his Derby side eliminate Manchester United in the previous round.
However, he will take on a Chelsea team unbeaten in 14 matches across all competitions under new boss Maurizio Sarri.
Make sure you don't miss a moment of the action courtesy of our minute-by-minute updates below.
It is a chance for Frank Lampard to come back and haunt the club he had so much success at on Halloween night, with his Derby side looking for a second successive giant-killing in this season's competition. The hosts are the firm favourites going into the game, though, so it should be an intriguing contest!
Let's start with a look at the team news...
Well, we'll start with the hosts who, as expected, make a number of changes from the weekend win over Burnley - eight, to be exact.
The only players to keep their places from that victory at Turf Moor are N'Golo Kante, Alvaro Morata and Willian, the latter two of whom were both on the scoresheet at the weekend.
The Belgian was not expected to be risked this evening as he continues to edge his way back to fitness, and Chelsea have not exactly struggled in his absence.
The England international came off the bench to score against Burnley, making it four goals in his last two games for the club having also netted a hat-trick against BATE in the Europa League last week.

Cahill also featured in the last round against Liverpool, and from that XI at Anfield Chelsea make just three changes with Zappacosta, Kante and Loftus-Cheek coming in.
The Rams are missing Bryson - who was the last Derby player to score against Chelsea, incidentally - Evans, Ledley and Olsson through injury, but they do have a couple of players notably available.
The Blues believe that the experience of this match could prove valuable for the duo and are willing to risk them having an impact on the game by allowing them to savour that experience - a major boost for Derby.

Malone, Huddlestone, Waghorn, Lawrence and Marriott all come into the side, and the latter came off the bench to score at Old Trafford so will be looking to add Stamford Bridge to his list tonight.
Chelsea have begun the season in superb fashion, with Maurizio Sarri quickly laying down his ideas and the players buying into them. All of the players appear to love playing for the Italian, which is certainly not the feeling given out with Antonio Conte in charge.
That Wembley loss remains Sarri's only defeat as Chelsea boss, with the club currently enjoying their longest unbeaten streak since May 2015.

The omens are good too; on both of the previous occasions they have gone on to win the title - once in 2005-06 when Lampard was in the team, and then again in 2014-15.
For Chelsea's part, they are also five points better off than they were at the same stage of last season and have established themselves as genuine title contenders now, but they still need to up their game if they are to keep pace in what is shaping up to be a thrilling title race.
Only Man City have now scored more goals than Chelsea in the Premier League this season, while only City and Liverpool have conceded fewer too.
In this competition specifically you have to go back to January 2013 for their last home defeat - against Swansea in the semi-finals - with six wins and a draw since then. That stalemate did come in their most recent such match - a 0-0 draw with Arsenal in last season's semi-final - meaning that tonight they risk going two home League Cup games without winning for the first time since 2005.
Such a result should give them huge confidence that they will progress tonight too, and they rarely slip up against such opposition - Chelsea have progressed from 18 of their last 19 League Cup ties against non-Premier League opposition, with the only exception coming at the hands of Burnley in 2008-09.

The former England international is sure to get a hero's welcome at his old stomping ground, where he scored a club-record 211 goals in 611 appearances between 2001 and 2014, winning 13 trophies along the way.

As a player Lampard did not lose on any of his last 19 matches at Stamford Bridge - one of which came as a Manchester City player - and he will be hoping to extend that streak into his managerial career tonight.
Derby overcame an early United opener to make a 2-1 lead in the 85th minute, only for Fellaini to then rescue penalties in the 95th minute. It was a very high-quality shootout too, but Phil Jones eventually became the first player to miss as Derby took it 8-7.

Derby themselves have not knocked out two top-flight sides in a single League Cup campaign since 1968-69, when Brian Clough was in charge as they eliminated Chelsea and Everton.
Derby have a decent record on the road in the EFL Cup, though, winning six of their last eight such matches, including the penalty shootout victory at Old Trafford last time out.
Both of those clean sheets did come in this season's competition, though - against Oldham and Hull - while if they avoid defeat tonight then they would have gone four away games without losing for the first time under Lampard.
Promotion is once again the goal for Derby this season after a few near-misses in recent campaigns, and as things stand they are on course to challenge for it once more. Lampard's side currently sit sixth in the Championship table, only two points off the automatic promotion places.
Derby pulled off a big upset in the last round, but that was against a United side in poor form whereas Chelsea are flying at the moment. It is hard to see past a home win.
SPORTS MOLE SAYS: 3-0
That is one of 22 successive matches in which Chelsea have scored against Derby, with the last Rams keeper to keep a clean being Peter Shilton way back in 1987.
The Blues unsurprisingly have a formidable record here too, winning each of their last eight home games against Chelsea in a spell which spans from 1990 and 2008.
Neither Derby nor Lampard will forget the last time the Rams came here either, with the now Derby boss scoring four times in a 6-1 Chelsea win in March 2008, with Kalou and Joe Cole also on the scoresheet.
CHELSEA STARTING XI: Caballero; Zappacosta, Cahill, Christensen, Emerson; Kante, Fabregas, Kovacic; Loftus-Cheek, Morata, Willian
DERBY STARTING XI: Carson; Bogle, Keogh, Tomori, Malone; Wilson, Huddlestone, Mount; Waghorn, Marriott, Lawrence
Zappacosta gets down the right and puts a low cross into the box which should be an easy one to clear. However, Tomori completely misses the ball with his attempted clearance and it hits his standing leg before dribbling past Carson and in.
A nightmare moment for the youngster!
Cahill really doesn't cover himself in glory as he gives the ball away and then falls over to allow the through-ball to find Marriott. The striker has time to pick his spot, and he slides his low finish past Caballero - who maybe should have done better.
1464 - Fikayo Tomori's own goal is the first that Chelsea have benefited from in the League Cup since Jermaine Grandison put through his own net for Shrewsbury in October 2014, 1464 days ago. Misfortune.

6 - Jack Marriott has been directly involved in six goals in his last five games for Derby County in all competitions (four goals, two assists). Response.

However, the winger gets the ball caught under his feet and in the end can only dig out a tame effort which is straight at the keeper. That should have been 2-1!
Loftus-Cheek pokes the ball out to Zappacosta, who again causes the problems with a fizzing low cross into the box. Keogh should still do better, though, as he steers the ball past Carson and into his own net.
This one stems from a throw-in on the left which eventually ends up with Mount being poked through down the left channel. The Chelsea loanee plays a low ball into the box for Waghorn, who cannot miss this time as he applies a simple finish at the back post!
Loftus-Cheek pulls the ball back from the byline for Zappacosta, whose attempted touch hits a Derby defender and falls at the feet of Fabregas. The Spaniard's first-time finish takes a slight deflection on its way through, and Carson cannot keep it out despite getting a hand to it.
Derby are still very much in this match despite trailing 3-2 at the interval, particularly considering that they have actually been responsible for four of the goals we have seen tonight. They will believe that there is something in this game for them.
It was a horrible moment of the youngster after only five minutes, but he was bailed out just four minutes later when Jack Marriott slid an equaliser past the keeper at the other end following a Gary Cahill error.
Keogh should have also done better as he failed to sort his feet out in time, but once more Derby responded quickly when Waghorn turned the ball home from close range at the back post.
2 - Derby County are the first team to score two own-goals against Chelsea since Stoke City did so in the Premier League in January 2013. Spooked.

7 - Cesc Fabregas has had a hand in seven goals in his last seven League Cup appearances for Chelsea (three goals, four assists). Reliable.

Derby scored four of the five goals which all came in a remarkable first half, but unfortunately for them two of them came at the wrong end. Jack Marriott and Martyn Waghorn quickly responded for the Rams after the own goals from Chelsea loanee Tomori and Keogh, but Fabregas's goal four minutes before half time proved to be the winner.
There was another bad stroke of luck for Derby late on, though, as Nugent saw his effort hit the inside of the post and rebound back into the arms of Caballero.
Thank you very much for joining Sports Mole for this thrilling EFL Cup tie as Frank Lampard's return to Stamford Bridge is spoiled by two own goals as Chelsea progress into the EFL Cup quarter-finals at Derby's expense. I will leave you with our match report, and be sure to stick around for reaction too.
From me, though, it is goodbye for now!
