… and so Chelsea, Manchester City, Leicester City and Aston Villa go into the velvet bag for the fourth round. Already in there, having won their ties last week: Brentford, Brighton & Hove Albion, Crystal Palace, Manchester United, Preston North End, Sheffield Wednesday, Southampton, Stoke City and Tottenham Hotspur. Three ties remain, with two of them – Arsenal v Bolton Wanderers and Liverpool v West Ham United - to be played tomorrow night, after which the draw for the fourth round will be made. Hope you’ll join us for all of that. Thanks for reading this Clockwatch! Nighty night.

FULL TIME: Wycombe Wanderers 1-2 Aston Villa. Villa were the party poopers on Wycombe’s 137th birthday. Here’s Ben Fisher’s report.

FULL TIME: Manchester City 2-1 Watford. Jamie Jackson was at the Etihad to witness City record a 16th consecutive win against the Hornets.

FULL TIME: Chelsea 5-0 Barrow. Christopher Nkunku scored a hat-trick to swat aside the League Two leaders. Taha Hashim reports from Stamford Bridge.

PENALTIES: Walsall 0-3 Leicester City. Liam Gordon goes bottom left … and it’s pitifully weak. Danny Ward could throw his cap on it, but carefully palms it away instead. Leicester are through!

PENALTIES: Walsall 0-3 Leicester City. Oliver Skipp sends a third Leicester penalty into the bottom right. Simkin guessed correctly but couldn’t get over there.

PENALTIES: Walsall 0-2 Leicester City. David Okagbue has to score for the hosts … but he can’t do it. He whips towards the left-hand side of the net, but Danny Ward guesses correctly and turns it away. Another fine save.

PENALTIES: Walsall 0-2 Leicester City. Conor Coady up next. He sends Simkin the wrong way, and rolls calmly into the bottom right.

PENALTIES: Walsall 0-1 Leicester City. Taylor Allen goes bottom left … but Danny Ward stops it! Not the greatest penalty, but that’s a fine save nonetheless.

PENALTIES: Walsall 0-1 Leicester City. Leicester to go first. Ricardo Pereira confidently lashes into the bottom-right corner. Tommy Simkin goes the right way but can’t reach it.

Manchester City 2-1 Watford. A free kick for Watford and a chance to load the City box. Giorgi Chakvetadze sends it in from the right, but Jack Grealish slides in to hook it clear. That’s wonderful defending.

Chelsea 5-0 Barrow. Chris Stokes grabs a big handful of Marc Guiu’s shirt. If this was goalless, the whistle might blow for a penalty. But it’s not, and there are less than ten minutes to play, so the referee shows some clemency.

Chelsea 4-0 Barrow. So nearly a consolation goal for Barrow. A corner comes in from the left. A proper penalty-box stramash. Theo Vassell swings and misses. The ball pings up to Junior Tiensia, who flicks goalwards, but it’s an easy gather for Filip Jörgensen. On another day, that might have pinballed into the net.

Manchester City 2-0 Watford. Another big chance for Watford. With City pressing forward, Giorgi Chakvetadze robs Phil Foden and steams upfield on the break. He slips the ball left to Kwadwo Baah, who drops a shoulder to get past John Stones before lashing a low drive wide left. He should have worked Stefan Ortega at the very least.

Manchester City 2-0 Watford. Savinho sends a power curler towards the top left. Tom Ince clears off the line with the bravest of headers. Great play all round. “That Nathan Lowe (8.56pm) sounds like a bit of a speed merchant,” writes Merrie Melodies aficionado Simon McMahon, identifying and utilising the second-best MEEP sound in comedy history. The greatest? I won’t insult your intelligence by belabouring the point.

Manchester City 2-0 Watford. The hosts continue to dominate, without threatening to sweep Watford away. There’s still time. Meanwhile, on the Hornets being level at 2-2 in a nearby parallel universe (8.35pm), here’s Julian Borrill: “Since we don’t have a metric for the distance between universes, ‘nearby’ is ill-defined. On the other hand, if our universe is infinite then they are already level in some other Hubble volume. In either case we should let Lev Landau have the last word: ‘Cosmologists are often in error but never in doubt.’”

Chelsea 4-0 Barrow. The cheer that met Pedro Neto’s goal wasn’t the loudest at Stamford Bridge since the break. That roar was generated by the half-time arrival of Ben Chilwell, who is looking to rebuild his Chelsea career after being told to do one by Enzo Maresca. The home faithful making their feelings on the matter known.

Walsall 0-0 Leicester City. Nathan Lowe scampers down the left, reaches the byline and tugs back for Albert Adomah, who opens his body but from six yards sends a sidefoot wide right. A huge chance to sprinkle a little shock-infused sparkle goes by.

The 7.45pm matches are underway again. In lieu of any looming upsets, here’s this.

Wycombe Wanderers 0-0 Aston Villa. Beryly Lubala bustles under a long ball down the Wycombe inside-left channel and cuts back for Matt Butcher, who leans back and skies an effort from the edge of the box. Butcher had more space and time than he thought.

Wycombe Wanderers 0-0 Aston Villa. There’s not a lot going on at Adams Park. Villa pass it around the back, every which way but forward. The crowd pretty flat as well. It’s not exactly a cup-tie cauldron.

Manchester City 2-0 Watford. Festy Ebosele crosses from the left and finds Vakoun Bayo unmarked, six yards out. Bayo flashes a header wide left. He should have scored. Factor in the disallowed goal, the whistle going rather sympathetically for Kwadwo Baah’s shoulder barge on 16-year-old Kaden Braithwaite, and Watford will consider themselves a little unfortunate to be where they are. In a nearby parallel universe, it’s level at the Etihad.

Chelsea 3-0 Barrow. Another big save by the Barrow keeper Paul Farman, who has been in the thick of it tonight all right. João Félix breaks clear down the middle and creams a shot towards the bottom right, but the keeper gets down well to stick out a strong hand. Then the whistle goes; turns out Félix handled as he broke clear, but hats off to the overworked keeper nonetheless.

Wycombe Wanderers 0-0 Aston Villa. … meanwhile Villa, who have five League Cups in the bag, are also being held by their lower-league opponents. Jhon Duran has another good opportunity to open the scoring, but lifts his effort over the bar.

Walsall 0-0 Leicester City. Leicester are dominating possession but home keeper Tommy Simkin hasn’t had too much to do. The three-time winners being held comfortably enough by their fourth-tier hosts. “But surely Charles Antaki (8.07pm) is right?” begins Richard Hirst. “By not playing, Haaland is failing to score every minute, so the trombone should be on permanent loop.” A fair point well made. Oh Scotty!

Manchester City 1-0 Watford. More uncertainty from Watford goalkeeper Jonathan Bond. Or perhaps too much certainty? He comes out to clear a Phil Foden cross but also succeeds in cleaning out his team-mate Ryan Porteous. Ooyah, oof. A collision that will certainly have hurt the Scotland defender, though happily he’s back up on his feet again soon enough.

Manchester City 1-0 Watford. Kwadwo Baah, barrelling down the right, brushes the 16-year-old debutant Kaden Braithwaite out of the way with absurd ease, before lashing past Stefan Ortega and into the net. But the whistle goes for the over-zealous nature of the shoulder-barge. Or was it an over-zealous use of the referee’s whistle? You’ve seen them given. You’ve seen play waved on, too. Watford will consider themselves unlucky, especially when they need all the help they can get against the best squad in the land.

Manchester City 1-0 Watford. “Is it sound-effects night?” asks Charles Antaki. “Excellent! I truly hope that at some point you’ll be able to use this one, preferably on the 15th occasion that Erling Haaland fails to score tonight. Yes I know it’s unlikely. But hey.” It’s unlikely all right, given that Haaland has been given the night off. Oh Charles!

Wycombe 0-0 Aston Villa. Completing our tetraptych of kick-off whistles. Jhon Duran immediately misses a one-on-one sitter.

Chelsea 1-0 Barrow. Could Paul Farman have done better for that opening goal? Perhaps that’s being harsh. Either way, though, the Barrow captain has more than made up for it by spreading himself to deny João Félix, who was clean through on goal. It looks like it’s going to be a busy night for the visiting keeper.

Chelsea 0-0 Barrow. A lively start for the fourth-division visitors, who are on the front foot early doors. A long throw-in from the left is allowed to bounce all the way through a crowded Chelsea box.

Whistles sound all across the land. Well, OK, in west London, east Manchester and Walsall. But they’re sounding! Wycombe to join the party in 15 minutes.

More on that crowdfunder to help AFC Wimbledon. “Just wanted to thank the Guardian for this article,” writes Owen Linderholm. “I wouldn’t have known otherwise (despite being a Wimbledon fan for over 40 years).” Anyone else interested in the fundraiser can find out about it here. At the time of posting this entry, it’s raised nearly £80,000.

AFC Wimbledon P-P Newcastle United. There was meant to be a fifth League Cup match tonight, but flooding at the Cherry Red Records Stadium did for that. The game will now be played at St James’ Park this time next week. But here’s some welcome good news for the club at an otherwise tricky time.
