Chris: Newcastle United. Experts in playing for penalties for 120 minutes.

Mike: This game is so terrible its not even going to give us the fun of penalties. I can feel it

I don't think it'll be too long before we see Kieran Tierney with the captain's armband. He is that type, he is a leader.

Andy Carroll rises high, but he's climbed up an Arsenal defender to get there.

A bit of relief for the Gunners.

Andy Carroll wins another Newcastle corner. He's put in a huge shift.

Steve Bruce's side are looking to snatch it late on...

Plymouth are really on top. Huddersfield can't seem to clear their lines in the box!

Michael: Can somebody remind Steve Bruce we don't get a point for the draw here

Ben Hamer to the rescue!

Plymouth open up the Huddersfield defence. It comes over to Ryan Hardie on the left side of the box and he fires it at goal.

Hamer tips it up and off the corner of the crossbar.

Andy Carroll swivels on the edge of the Arsenal box and thunders a left-footed strike towards goal.

It's deflected behind but Matt Ritchie's low corner only finds the front post, where Jeff Hendrick nudges wide from a tricky angle.

Great pace from Kieran Tierney. He went past DeAndre Yedlin like he wasn't there!

Off we go again at Brentford. Any response from Middlesbrough?

Superb ball from Kieran Tierney, right on to the forehead of Pierre-Emerick Aubameyang - every striker's dream. Aubameyang meets it but can only head straight into Ciaran Clark and Newcastle clear to safety.

There's a bit of last-ditch defending in the box by Plymouth before they try to release Ryan Hardie in space on the right.

The long ball is overcooked and it goes straight out for a throw-in.

Newcastle have been a really tough nut to crack for Arsenal - and they have offered a bit in the second half at the other end, too. I think Steve Bruce will be pretty pleased.

Two changes for Newcastle.

DeAndre Yedlin and 18-year-old debutant Elliot Anderson come on for Joelinton and Miguel Almiron.

Nine changes for Manchester United this evening, with only goalkeeper Dean Henderson and midfielder Scott McTominay, who is named as captain, surviving from Wednesday's EFL Cup semi-final defeat by Manchester City.

It means a place on the bench for Bruno Fernandes, who is joined by former Watford striker Odion Ighalo, who could make a farewell appearance for United given his loan ends at the end of the month. Paul Pogba is not involved.

It's a first FA Cup tie for new Watford manager Xisco Munoz, who has presided over a win and a defeat in his two games in charge.

Joao Pedro returns from injury, whilst Philip Zinckernagel is given his debut following the Dane's arrival at Vicarage Road last week.

Man Utd XI: Henderson; Williams, Bailly, Tuanzebe, Telles; McTominay, Van de Beek, Lingard; Mata, James, Greenwood.

Subs: De Gea, Matic, Ighalo, Fred, Fernandes, Martial, Maguire, Wan Bissaka.

Watford XI: Bachmann; Navarro, Troost-Ekong, Sierralta, Masina; Chalobah, Hughes, Sarr, Zinckernagel; Pedro, Gray.

Subs: Foster, Ngakia, Wilmot, Sema, Dalby, Barrett, Hungbo, Crichlow, Phillips

Remember, no replays. So extra time and penalties will decide this if it stays a draw.

Surely another goal (at least) to come?

Emile Smith Rowe, socks round his ankles, can't muster an effort on target but he is taking up good positions. Andy Carroll has gone down in the Arsenal half and that will be worrying for Steve Bruce.
