Craig: I still think Ruben Amorim should be playing two up top & one number 10. With two number 10s currently playing, they don't seem to be pressing. If Hojlund is pressing, who's in the box if a mistake is made?

Eddie Howe turns to his bench and Emil Krafth is going to come on.

Jacob Murphy delays, trying to allow the change to happen, but the referee says he's time-wasting and shows the Newcastle man a yellow card.

At the next stoppage, the substitution does happen. Krafth on for Anthony Gordon.

Just as I typed that, Cole Palmer lifts a ball out to Marc Cucurella on the left side of the penalty area.

The left-back takes a touch and hits a firm effort towards the far corner but Nick Pope gets down well to parry it away.

Positive signs for Chelsea, though.

Good spell for Chelsea, keeping the ball around the Newcastle penalty area.

But they're still struggling to conjure any chances of note. Or just chances full stop, really.

The corner is floated to the back post when Alexander Isak is unmarked but he slices the volley high over the bar.

Good run in behind from Alexander Isak but Lewis Colwill does well to put the ball behind for a corner.

Isak then calls for more noise from the Newcastle fans as Sandro Tonali wanders over to take the set piece.

It's getting a bit spicy again with Dan Burn taking no nonsense as he takes the ball off Pedro Peto.

But Chelsea win it back with another forceful challenge from Moises Caicedo.

Sven Botman is off after just his fourth Premier League start of the season.

On comes Lewis Miley. That surely means a change of shape for Newcastle.

Fabian Schar is the first Newcastle player booked after going through the back of Enzo Fernandez.

I'd say he can have no complaints but it's very rare that a player won't argue with a yellow card decision - and this is not one of those occasions.

Ruben Amorim makes six changes to his starting line-up from the midweek win over Athletic Bibao, with two-goal Mason Mount amongst those to start. Amad Diallo makes his first start since 7 February, with Harry Amass occupying the other wing-back berth.

Manchester United XI: Bayindir, Mazraoui, Yoro, Shaw, Amad, Ugarte, Mainoo, Amass, Fernandes, Mount, Hojlund.

Subs: Heaton, Lindelof, Maguire, Dorgu, Eriksen, Garnacho, Casemiro, Fredricson, Chido.

West Ham make three changes to the side that drew with Tottenham last week, with Lucas Paqueta not included in Graham Potter’s squad. Vladimír Coufal returns to the side while Aaron Cresswell is also included even though the club announced earlier this week the pair would be leaving in the summer along with Łukasz Fabiański and Danny Ings.

West Ham XI: Areola, Todibo, Kilman, Cresswell, Wan-Bissaka, Soucek, Ward-Prowse, Rodriguez, Coufal, Bowen, Kudus.

Subs: Fabianksi, Carlos Soler, Emerson, Paqueta, Mavropanos, Luis Guilherme, Alvarez, Ferguson, Fullkrug.

Newcastle need to be careful not to overcommit in searching for a second goal.

They're leaving themselves a little exposed on the counter-attack and Chelsea have started this second half with plenty of belief.

Good defending from Dan Burn keeps Pedro Neto at bay on this occasion, though.

The referee has a great view. It's a terrific pass and a great run. It's just a shoulder from Reece James.

There's not a lot in it.

Newcastle want a penalty as Anthony Gordon goes down in the box after a nudge from Reece James.

The referee determines it was shoulder-to-shoulder rather than a push in the back.

Oh dear. Tino Livramento stays down after landing awkwardly and looks to have injured his knee.

There is concern from players on both sides but it looks like a happy outcome as, after a bit of treatment, the full-back gets to his feet with a smile.

We'll have full team news from Old Trafford very shortly.

Andre Onana is not in the Manchester United squad. Mason Mount and Amad Diallo both start.

We're back under way for the second half at St James' Park.

I think most would expect Newcastle to try to push on and make this game safe but can Chelsea do anything to force their way back into this one?

A change at the break for Chelsea.

Reece James in on for Noni Madueke.
