This is a game that Thomas Frank won't dwell on. He's got to put it to bed quickly and think, 'We didn't turn up.'

Harvey Barnes smashes in a shot from 20 yards which beats Mark Flekken but cannons off the post. Newcastle cruising.

Shooooot say the Toon fans as the ball comes near Sandro Tonali.

Into the final 20 minutes. Will Southampton, who have been second best for large chunks but have come alive since scoring, find an equaliser and force penalties?

Liverpool have sent on Diogo Jota and he provides fellow substitute Federico Chiesa with a great chance inside the box but the Italian's attempt is cleared by Taylor Harwood-Bellis.

Was it on target? Replays suggest Chielsa's attempt was going wide.

All Newcastle now. Brentford have given up hope it feels.

It's been easy for Newcastle all night but it is even easier now. A lot of heads have dropped in the Brentford side. So easy for Newcastle.

Chance for a Sandro Tonali hat-trick as a corner is half-cleared to him but his effort is blocked by Paris Maghoma.

Around 25 minutes plus stoppages left.

It's pouring down with rain again and Southampton's tails are up.

Liverpool are trying to take the sting out of the tie but the home side are putting up a real fight.

Much, much better from Saints after their crushing defeat at the weekend.

Triple change for Newcastle now with William Osula, Miguel Almiron and Kieran Trippier replace key trio Alexander Isak, Lewis Hall and Anthony Gordon.

Brentford send on Jayden Meghoma and Paris Maghoma.

All over and Gabriel Jesus' hat-trick sends Arsenal into the EFL Cup semi-finals!

The corner sails over Dean Henderson and David Raya punches away.

That is surely that?

One minute to go and Crystal Palace have a corner. Up goes Dean Henderson...

It's a fabulous, fabulous finish from Cameron Archer.

Mateus Fernandes' ball hits Wataru Endo on the face and ricochets back into play. Archer picks the ball up. He is direct, cuts inside and he wraps his foot around the ball. It nestles in the far corner.

It gives Southampton fans something to celebrate which they haven't had for a long, long time.

Southampton have come alive!

It requires a flying one-handed save by Caoimhin Kelleher to deny Cameron Archer an equaliser from close range.

Fair play to Southampton and their fans. St Mary's is bouncing.

Bryan Mbeumo crosses and Yoane Wissa, under pressure, heads over for Brentford. There is still time if they did pull one back.

The 90 minutes are up and there will be five minutes of stoppage time.

A glimmer of hope for Crystal Palace.

A simple goal. Newcastle just kept the pressure on when the ball was bouncing around in the box and eventually Bruno Guimaraes picked out Fabian Schar and it is a simple tap in.
