Rashford to Arsenal?
Martin
Newcastle 1-0 Brentford
Newcastle captain Bruno Guimaraes loses the ball and stands on the foot of Vitaly Janelt while trying to get it back. Yellow card.
Darwin Nunez
A wild attempt one moment, a lovely finish the next.
Darwin Nunez silences Southampton fans who have been goading him with a neat finish past Alex McCarthy after a mis-kick by Jan Bednarek.
The holders have the lead!
Newcastle 1-0 Brentford
Newcastle winger Anthony Gordon gets the ball on the left, racing onto a long ball. He cuts in and smashes a shot over the bar from 12 yards. He wants a corner but the referee doesn't think Nathan Collins gets a touch.
Southampton 0-0 Liverpool
Francis Benali
Former Southampton defender on BBC Radio 5 Sports Extra
The centre-backs for Southampton are positioned exactly like they were under Russell Martin. But goalkeeper Alex McCarthy is kicking the ball long more which is getting the team forward a lot quicker than we have seen whole season.
Southampton 0-0 Liverpool
That's a lovely sliding tackle by Jan Bednarek to prevent Darwin Nunez from getting a shot away inside the box after Cody Gakpo's threaded pass. It's greeted by a roar from the home fans who like what they are seeing from their side so far.
Newcastle 1-0 Brentford
Newcastle work a corner short. Lewis Hall takes it and gets it back before picking out Jacob Murphy but the winger skies a first-time shot from about 25 yards.

Mateta is a bit like Peter Crouch, because he's tall you think he's just a target man. But he's actually brilliant with the ball at his feet and a class finisher.

Southampton 0-0 Liverpool
The biggest cheer of the night as Darwin Nunez goes from glory from 20 yards. It's a wild attempt. He cannot use the conditions as an excuse for that.
Newcastle 1-0 Brentford
Chris Waddle
Former Newcastle & England winger on BBC Radio 5 Live
Aside from the goal there have not been very many things to talk about. In a quarter-final cup tie you expect end to end football, excitement and a lot of goal action but we've not seen it.

Why is it always got to be players like Gyokeres or Isak with Arsenal? Why not take a punt on someone a little more affordable and gettable? Pretty much anybody would be better than they have right now.
Tocowa
Newcastle 1-0 Brentford
Nathan Collins dallies on the ball too much and Anthony Gordon takes the ball off him. The Brentford defender knows he would lose that race and hauls him down for a yellow card.
Arsenal 0-1 Crystal Palace
So far, so good for Crystal Palace.
Arsenal 0-1 Crystal Palace
A lovely touch by Jean-Philippe Mateta and he is away from his marker. He gets into the box and tries to backheel into the path of Ismaila Sarr, but the Arsenal defence gets back to clear.
Newcastle 1-0 Brentford
Chris Waddle
Former Newcastle & England winger on BBC Radio 5 Live
It's positive play from Anthony Gordon. He tries to take his full back on, has two or three goes at it and eventually wins a corner out of it.
Newcastle 1-0 Brentford
Eddie Howe is watching something on a tablet with one of his coaches. I noticed someone else on the Newcastle bench with a denim jacket. Seems strange football bench attire.

Having watched Arsenal on Saturday, and again so far tonight, I can’t believe how often players take a few steps forward only to then stand on the ball and bring it to a standstill. There is absolutely no pace or urgency. A disciplined pub side could defend against this.
Gareth, frustrated
Newcastle 1-0 Brentford
Oxford have won a trophy more recently than Newcastle.

Does Tom the Geordie remember the last time Newcastle won a trophy?

Southampton 0-0 Liverpool
Southampton were 2-0 down after 12 minutes against Spurs at the weekend. They've prevented Liverpool from having a shot in the opening 12 minutes tonight.
