Bournemouth, meanwhile, will know that on one side, United will have a defender playing out of position. I'm sure they'll hope to double up down whichever side it is, with Evanilson running off Maguire and Tavernier staying pretty wide, looking to put ball into the box, while Rayan and Kluivert look to run af defenders and attack the area from a little deeper.
Defensively, Adams and Cook will patrol the central area from which United like to create, with Smith, on the right, playing a little deeper than Truffert, on the left.
So, where is the game? United will look to build through the middle of the pitch, Santos stepping in between the centre-backs to punch passes forward and Baleba looking to carry whenever he can. There's not much width or height in this side, so the onus will be on Tielemans, Amad and Mount to slip passes in behind the Bournemouth defence for Mbeumo, who'll attack the space.
As for Bournemouth, the headline news the return of Kroupi, who's on the bench. Otherwise, Rose makes one change to the side which beat Sunderland last weekend, Justin Kluivert replacing Ryan Christie.
Otherwise, Carrick goes for ballast in the midfield, with Andrey Santos and Carlos Baleba, which makes sense, but in front of him, there's a palpable lack of magic. Matheus Cunha, hooked at half-time in Como, drops out, with Amad one of the least dreadful when he came on, coming in on the right. His numbers tell us he's not the standard required, but he offers good out-of-possession work and gives the team balance, such as it is, the only dribbles in a team severely lacking one v one ability.
Otherwise, Mason Mount, every manager's favourite, is relocated to the left, while Bryan Mbeumo continues up front in the absence of Benjamin Sesko – which tells us plenty about what Carrick thinks of Joshua Zirkzee, despite his goal in midweek.
Taking a closer look at the United team, Leny Yoro is back after his midweek suspension. Before it, he looked, finally, to have established himself in the first XI and, though he's a centre-back, I expect he'll play right-back today, with Ayden Heaven, back in after illness, taking the spot in the centre next to Harry Maguire. That's because he'd never previously played left-back until forced to fill the spot away to Atletico – one of various things that so exercised Martinez. But now that you don't ask, I'd probably stick him there again, to get Yoro into his position – he's actually done better on the left of the two than on the right – and so Digo dalot can play on his natural side. We shall see.

Marco Rose says the last three games have passed and his team need to prove themselves again. He's been in the business long enough to know this could be a good moment to play United, but also a bad one if the players want to turn the noise down.
As a club they need to get used to the new demands of the Europa League so he needs to use his squad, but i's good to have Junior Kroupi back, as though he's not yet 100%, he decides game and is good to have in the locker room.
Old Trafford is a difficult place to play, but Bournemouth are confident and know what do, it's just about executing now.

Carrick tells Sky that you've got options when picking a team, it's always a difficult decision and they had to make one in the best interests of the team. Asked if it's because of what he said or how he's playing, he replies with "Pure football."
Lisandro Martinez isn't ready yet, he continues, Heaven was ill but has played well and United have strong options off the bench.
He wants United to play with humility and endeavour, Bournemouth are a really good team and United will have to play well to get a result. They want to flip the run and win a game and today is a good day to do that.

Reports from Old Trafford, broadcast by Sky, advise us that Bruno Fernandes has been dropped by Michael Carrick.
We don't know if it's for consistent poor form or midweek insubordination – it could be either or both – but either way, it's a shame it's come to this. Ultimately, United have broken Bruno, who's dedicated his career to elevating a club that has consistently let him down, and though he was out of line in what he said after Como, it didn't come out of nothing, well earned though his omission is.
An egg walks into a kitchen looking unhappy, so a chef asks what's up. "It's the spurtles," he says. "They beat me."
"What about the forks?" ventures the chef; "Yes, they beat me too," comes back the response, so there's a pause while the chef considers.
"Have you thought about hanging out with Manchester United?" he eventually offers. They don't beat anyone."
It's now almost two months since United won a league game, and that against promoted Ipswich – who now sit five places above them in the table. They did also manage a victory over Sabah, Champions League debutants, but otherwise, their start to the season has been miserable beyond conception, even by their august standards, and is rapidly getting worse. Already, it looks like yet another manager is toast, and this time, perhaps for the first time, there's no sense of where they could go next.
Just three weeks ago, a home game against Bournemouth was as close to a gimme as possible – even for them. Since then, though, consecutive home wins over Sturm Graz, Sunderland and Milan with eight goals scored and none conceded have flipped the Cherries' mood and they arrive at Old Trafford with Marco Rose ensconced and the club on a buzz. They'll fancy this, and really who wouldn't?
If that was the extent of our afternoon, it'd be plenty, but happily for us, it's not even close. At Anfield, Liverpool – who've also won three on the spin in uplifting fashion – entertain Brighton, already three points clear of third with a game in hand. They'll know a top-five spot is theirs for the taking and the way they're playing, who knows what else?
Those two matches will be our focus, but we'll also be updating from from KC where Hull, who might just be running out of form after a brilliant start, face Brentford while, at Selhurst, Palace meet Newcastle, struggling badly after a promising start under Matthias Jaissle. Or, in other words, this is going to be a lot of fun.
