While we wait on player and manager interviews the word on the street is that we're going to have a new British record transfer tonight.

Our dedicated deadline day page has the details.

Eddie Howe and his Newcastle players are currently being serenaded by the home fans as 'Hey Jude' rings out.

They stroll round the stadium showing their appreciation almost in disbelief at what they are seeing in the stands.

What a night on the Toon.

Rachel T: Eddie Howe will be given the Freedom of The Toon if he wins at the end of February. Wow. It doesn’t matter who you support - what lovely scenes at St James’s Park.

Newcastle recorded their 15th win of the season, in what was their 27th game.

This is the quickest they’ve reached 15 victories in a single season as a top-flight club since 2001-02 (24th game).

A club on an upwards trajectory (again).

It's special that Sean Longstaff got the goals tonight and with Burn playing too, there is a connection with this club.

Not a single Newcastle fan in this city will want to be anywhere but Wembley when this final takes place.

Newcastle are in their first major cup final since 1999 (FA Cup), and their first League Cup final since 1976.

St James' Park is in raptures.

What a brilliant moment for these fans. They've waited so long.

It's a glorious night for them, although it wasn't a glorious performance. Sometimes you just have to get over the line and over the tie they have deserved it.

Que sera, sera time for Newcastle. They are in the EFL Cup final on Sunday, 26 February.

Che Adams takes a pop for Southampton but that's blocked. The Newcastle fans are urging their team to keep the visitors out.

Still Southampton press forward. Newcastle are defending resolutely mind.

Another change for the hosts. Elliot Anderson comes on for Jacob Murphy, who only came on as a sub himself on the hour mark.

That goes down as a chance. James Ward-Prowse passes a corner into Romeo Lavia who blasts over.

Was that Southampton's last chance?

Newcastle forward Alexander Isak goes off and is replaced by defender Jamaal Lascelles.

MBoyerUSA: Yellow for me. Both going for the ball. Bruno goes in with toes and he risks injury to his ankle (rolling). Looked nasty but I say yellow.

If Isak has gone down complaining of anything to do with his head he should go off the field now and shouldn't be let back on.

The referee has told Eddie Howe he won't start the game until you get that player off the field.

Well done referee, that's spot on.

Southampton keeper Gavin Bazunu steams forward as his team have a corner. Meanwhile, Newcastle forward Alexander Isak is down.

He blocked a James-Ward-Prowse effort with his head before and looks to be struggling.

Romain Perraud goes for glory from distance but the Saints left-back sees his shot blocked.

Newcastle have everyone behind the ball now. Southampton are probing for an opening.

They still need two goals though to take this game to extra time.

There are going to be SEVEN added minutes.

Sekou Mara replaces Mohammed Salisu for Saints.
