Dele Alli eases Tottenham's Wembley troubles after Barnsley win.

Well that is all we have time for on this live blog. But don't go anywhere as we still have three games which have entered extra time. An additional 30 minutes will be played at Bournemouth, Wolves and Burnley, and you can follow the twilight of the matches here.

Full time: Reading 0-2 Swansea

A much-needed win for Paul Clement's men as they double their goal tally for the season in beating Reading to reach round four. Alfie Mawson scrambled one home from a corner before Jordan Ayew struck on the break after a Reading attack was stopped by the ball striking the referee.

Full time: Tottenham 1-0 Barnsley

Not the most memorable evening but Spurs get the job done and are into the fourth round. Dele Alli scored the goal and downed Championship Barnsley, who worked hard but struggled to create enough clear-cut chances.

Seventeen-year-old Tashan Oakley-Boothe on for Dele Alli in stoppage time at Wembley. What a moment for the teenager.

Four added minutes at the Madejski.

Barnsley are huffing and puffing but not offering a great deal at Wembley. Tottenham have closed the game down since Dele Alli's goal. The Premier League side look like they're edging through.

Swansea celebrate going ahead in the first half.

GOAL! Reading 0-2 Swansea (Jordan Ayew)

Swansea are heading through to the fourth round but this goal with wrangle with Reading supporters. A Royals attack is halted as a cross-field pass hits referee Andy Davies. The Swans collect possession and with the Championship side having thrown players forward they are sitting ducks, and substitute Ayew cuts inside and thumps into the corner. The home faithful are not happy.

Not much happening at the Madejski to be honest. Reading not playing like a wide who need a late goal to force extra time or to spark a comeback. Swansea pretty comfortable.

How has Wilfried Bony missed there! Ayew drives the cross in and Anthony Jaakkola palms the ball against the Ivorian and the ball rebounds wide. Should be two.

Good bit of context behind tonight's attendance.

Georges-Kévin Nkoudou on for Tottenham. Glad someone remembered where he was buried. Time to kick-start his career in England.

Dele Alli slides Tottenham ahead in the second half.

Attendance at Wembley this evening is 23,926. The magic of the cup.

GOAL! Tottenham Hotspur 1-0 Barnsley (Dele Alli)

The deadlock is broken at last as Trippier beats his man and crosses for Dele Alli, who slides the ball home after 65 minutes. The relief is almost tangible around Wembley.

First nervy moment for Barnsley in this second half. Kieran Trippier is at the centre with a fine cross towards Llorente and when he can't make contact, Winks cuts the ball back and Davies makes the block.

Wayne Routledge storms into the Reading box but via Ilori and Jaakola the ball is put behind for a corner. Jaap Stam's side have offered nothing since the goal after being very competitive in the first half.

Tottenham's fans are growing a little restless as we approach the hour mark at Wembley. Barnsley have grown in confidence as this game has progressed and can even claim to have had the better chances. A cup-set is certainly on.

GOAL! Reading 0-1 Swansea City (Alfie Mawson)

Finally we have a goal at the Madejski and it comes for the Premier League side. Mawson meets a corner at the near post and his volley hits Chris Gunter and bounces into the net. Not an own goal I don't think, but Gunter made a hash of trying to clear the shot.

No shots on target in the first half at Wembley, but we get one inside 15 seconds of the second period as Ugbo takes aim with a thumping volley from 30 yards which Vorm pushes over the bar. On loan from Chelsea, is the Barnsley forward.

Back under way at the Madejski Stadium.

The only punishment stemming from that clash at the end of the first half was a booking for Bacuna. Very much handbags.

Half time: Tottenham 0-0 Barnsley

Spurs have dominated the game but are yet to have a shot of target. Otherwise, it has been pretty dreary for the most part. Not my favourite game of the season.

Half time: Reading 0-0 Swansea City

Some incident at last and it comes after the half-time whistle has gone. Liam Moore is involved as is Wilfried Bony it appears as a scuffle breaks out by the tunnel. The referee has held talks with his assistant and we await to hear the outcome of that.

No attempts on target from Tottenham's 10 on goal this evening. Barnsley have been pretty comfortable, if not always in control.

A long Reading passing move ends with Swift attempting an ambitious cross from around 30 yards out which bounces through to Nordfeldt. Just about sums up the half.

Corner for Barnsley. Can they hurt Tottenham, who have a new centre back in toe tonight?

Lindsay gets a free header at the near post but can't find the target. Barnsley should be ahead.

Renato Sanches shoots again from around 35 yards. It doesn't go well. He skies it.

Dele Alli has a rare effort on goal.

The most entertaining thing about this Tottenham-Barnsley game is the commentator on my feed pronouncing Jan Vertoghen in a Dutch accent.

That's how bad it has been.

This. This.

Just four goals in the Carabao Cup ties which have reached half time. But where have they come? Head to our live blog to find out.

Half chance for Reading as a corner from the right is over hit and it comes to Roy Beerens, who shifts the ball onto his right foot but he can't keep his effort down and it flies over.

Nice move from Spurs as Sissoko raids down the right, crosses towards Alli who dummies it but there is no teammate to take advantage.

Meanwhile, Renato Sanches' tough start to the campaign continues he has lashes well wide of the Reading goal.

Chance for Tottenham at last as Kieran Trippier's corner is headed goalwards by Llorente but his maiden goal evades him as he misses the target. Davies remains untested.

No player happier at Wembley right now that the Barnsley goalkeeper Adam Davies, who has had barely anything to do.

Meanwhile, ball in the net at the Madejski as Narsingh slides into the corner, but he is adjudged to have fouled Liam Moore. The Dutchman then goes through on goal but as he loses control Jaakkola comes out and makes the save.

First bit of pressure from Swansea as Narsingh crosses but Reading deal with it with ease. Not getting loads of chances in either game to be honest.

Swansea offering absolutely nothing in the opening 20 minutes at Reading. They look every bit a team who have only netted twice this season. Wilfried Bony particularly ineffective.

Barnsley have more than held their own in the early moments against Tottenham.

Harry Winks has the chance to put the pressure on Barnsley but his cross is over hit and Davies rises to take the catch.

Adrian Popa proving to be a real handful for Swansea and his turn on the edge of the box leaves Mawson on his backside. His shot leaves a lot to be desired however as he lashes over left-footed.

Barnsley more than holding their own in the opening minutes, with Hedges' raid down the left an example of their intent. Spurs neat and tidy but not really probing.

Chances in both games early on.

Popa gets in behind Swansea 'keeper Nordfeldt and though he allows him to get back his cross had to be hacked clear by Alfie Mawson.

For Tottenham, debutant Juan Foyth heads wide when he should do better.

Under way in both of our featured games.

Teams are out at Wembley and the Madejski ahead of tonight's two remaining games. Will we see a surprise, or can the Premier League sides edge through. Extra time and penalty can be played if we need it.

Barnsley have already played twice in this year's competition and beat derby County in a five-goal thriller to book a meeting with Tottenham. They reached the FA Cup semi-finals in 2008, eventually losing to West Brom, but can they continue their run in the competition?

Wembley looking resplendent before kick-off.

Spurs out to warm-up at Wembley, led by surprise inclusion Mousa Dembele.

Meanwhile, at Selhurst Park the imagination of all fans has been captured by the Carabao Cup....

There are nine other ties taking place, kicking of at 7:45pm tonight. The main game sees Leicester City host Liverpool, just four days ahead of the pair's clash in the Premier League. Join Rhod Cannon for live coverage of that game and the other eight here. Kick-off in those games is fast approaching.

Barnsley's players are out soaking up the atmosphere. Not that many of them will be strangers to this sort of stage.

The other game we're focusing on tonight sees Reading host Swansea in a repeat of the Championship play-off final from 2011. That day the Swans, then managed by Brendan Rodgers prevailed 4-2 against the Royals. Below is the full team news ahead of the game, and we'll have news of all the goals as they go in.

One name which would have resonated with Tottenham fans from the Barnsley team is that of former defender Zeki Fryers, who had a somewhat inauspicious spell with the club a few years ago.

After joining from Manchester United he made 16 appearances in all competitions in the 2013-14 campaign and was offloaded to Crystal Palace. He move to Barnsley only came in the summer and tonight represents his debut for the Championship side. And what a time for it.

Five changes in all made by Paul Heckingbottom, in response to that heavy 3-0 defeat to Aston Villa.

Out go Adam Jackson, Matty Pearson, Adam Hammill, George Moncur and Tom Bradshaw. In their place come club captain Angus MacDonald, Zeki Fryers, Jared Bird, Ryan Hedges and Ike Ugbo, the Chelsea loanee.

And here comes the Barnsley 11.....

I make that six changes for Tottenham from the draw with Swansea. In come Vorm, Walker-Peters, Wink and Dembele. The is a full debut for Fernando Llorente and a first appearance for Juan Foyth.

Tottenham team drops.....

If you though the news that Rio Ferdinand wants to be a boxing was the worse of the day, things have got a lot worse. Look away Spurs fans....

Barnsley have landed at Wembley. Their natural habitat for most of last season.

BREAKING NEWS

Not a pun linked to Tottenham's form at Wembley, I promise.

These two sides have only met once in this competition, back in the day when each round included a home and away leg. Spurs won both games in that occasion.

Their last meeting in all competitions came back in the 1998-99 FA Cup, when David Ginola's wonder goal beat the Yorkshire side. You can watch that goal, voted goal of the season from memory, below.

Barnsley meanwhile have Ryan Hedges available after he picked up a knock against Aston Villa. Lloyd Isgrove and Dimitri Cavare are both missing however for Paul Heckingbottom's men.

So how might Tottenham line-up tonight?

Well Fernando Llorente could make his full debut after a handful of cameo appearances since his deadline day move from Swansea. Michel Vorm and Kyle Walker-Peters can also expect to be involved.

Marcus Edwards - labelled the new Lionel Messi by his manager Mauricio Pochettino last season - will not be involved however. Harry Wink is also in contention. Erik Lamela (hip), Danny Rose and Victor Wanyama (both knee) are all missing.

Forgive me for sounding like a broken record, but Tottenham face another key night in their attempt to dismiss their Wembley hoodoo. Spurs have won one of their last six at the national stadium, and despite overcoming Borussia Dortmund last week the draw with Swansea saw the return of some familiar problems.

Barnsley might be not be enjoying the best of seasons upon their return to the Championship, but they can shelve their domestic troubles and concentrate on winning again on a ground which unlike their opponents, they have a good recent record. The Tykes won two trophies at Wembley in 2016 but a third win on the trot tonight might be the most impressive result of them all.

Tottenham vs Barnsley is not the only 8pm kick-off tonight, with another Championship vs Premier League battle taking place in Berkshire, where Swansea City travel to last season's beaten play-off finalists Reading. Meanwhile, there are nine other games to get your teeth into here.

All the team news and build-up ahead of the 8pm kick-offs on the way.
