Mixed memories
The last time United played Tottenham in the League Cup was back in 2009, when a brace from Darron Gibson handed the hosts a 2-0 win.
United have won just three of the eight League Cup ties against Spurs.
The last time United played Spurs away in the competition was in 1998, when Tottenham won 3-1, Teddy Sheringham getting United's only goal.
When is the draw?
Sky Sports have confirmed that the live draw will take place at around 10.40pm, so not long to go.
This year, it's an all-Premier League last eight for the first time in 14 seasons. United have reached the quarter-finals for the fourth time in six seasons.
When are the quarter final matches?
The next round of games will be played in the week of December 16.
The semis are set to be over two legs - as normal - with first legs over the week of January 6 and the second leg almost one month later.
The final is on Sunday, March 16.
Defeat for Man City
Eight-times League Cup winners Manchester City fall to Tottenham 2-1 and fail to make the quarter-finals for the second year running.
Matheus Nunes grabbed City's only goal of the game, with the Blues acquiring new injury concerns with Savinho and Manuel Akanji.
United victorious
The only goal of the second half came from Bruno Fernandes, who led United to a 5-2 victory over Leicester City.
They move into the quarter-finals, the draw for which is coming up soon.
Stay tuned to find out who United will face.
Manchester United ahead
United went into the break against Leicester 4-2 up thanks to a brace from Casemiro and goals from Bruno Fernandes and Alejandro Garnacho.
It's going well in Ruud van Nistelrooy's first game as interim boss.
Second half is underway...
When will the quarter final ties be played?
The matches are due to take place in the week commencing Monday, December 16, meaning that they will likely be on December 17 or 18.
The semi-finals, which are two-legged, are then set for January 6 and the second leg in the week of February 3.
The final will be at Wembley on March 16.
What are the competition rules for tonight?
Matches tonight will be played to 90 minutes with no extra time if it ends as a draw.
There are no replays in the Carabao Cup with matches instead going straight to a penalty shootout.
United agree deal with Sporting for Ruben Amorim
Just breaking off from the Carabao Cup updates for a second...
Manchester United have agreed a fee with Sporting Lisbon for Ruben Amorim.
Sporting confirmed on Tuesday that United had expressed an interest in triggering Amorim's release clause of €10million (£8.3m) as talks over a compensation package progressed.
The Manchester Evening News can reveal United have agreed a fee to appoint Amorim and the club are now working on a deal to bring his Sporting first-team coaches to Old Trafford.
Who is in the Carabao Cup quarter-final draw?
So far only Brentford and Southampton. They both played last night.
Brentford went to penalties after a 1-1 draw with Sheffield Wednesday whilst Saints beat Stoke 3-2.
The fourth round ties tonight will determine who enters the quarter final draw.
The matches are: Brighton vs Liverpool, Preston North End vs Arsenal, Newcastle vs Chelsea, Aston Villa vs Crystal Palace, Manchester United vs Leicester City, and Tottenham vs Manchester City.
When is the draw?
Starting off simply.
There is no set time but it will take place after the Spurs vs City match, which is scheduled to be last of the night to kick off, down for 8:15pm.
If there are no penalties then it should be finished by 10:15pm at the latest, really, unless there are some seriously long stoppages.
The draw, then, will hopefully be starting by 10:30pm (again, at the latest), and finished by 10:45pm.
If it goes to penalties then we're probably looking at another 20 minute delay on top of this.
Good afternoon
We're into the final few hours before team news will start to come out for the 7:30pm and 7:45pm matches tonight, whilst there will be a longer wait for Tottenham and Manchester City.
It's the Carabao Cup fourth round with a place in the quarter final up for grabs and plenty of the Premier League's top sides all in action.
We'll have all the details you need to watch, stream, follow, keep up to date, and live through the night up towards the draw. Don't go anywhere!
