It’s official.
Former Manchester United midfielder Michael Carrick has been confirmed as the Red Devils’ interim manager until the end of the season, inheriting the wreckage left behind by Ruben Amorim’s tumultuous reign.
The Portuguese manager presided over one of the worst eras in decades at Old Trafford, with his side finishing 15th in the Premier League last season, the club’s worst finish in 40 years.
Much of the woes stemmed from a refusal to vary his formerly trusty 3-4-2-1 system.
The tactic brought Amorim considerable success in his homeland, as he led Sporting CP to two Portuguese titles in four years.
However, in Manchester, success was much harder to come by, and after a run of back-to-back draws with relegation-threatened Wolves and Leeds, the Old Trafford hierarchy had seen enough.
Now, Carrick steps into the hotseat, but even as he does, online betting sites remain unconvinced.
The latest Premier League betting odds list United as a 5/1 outsider to finish in the top four this season, let alone mount a title challenge.
The implied probability from those odds makes for even worse reading.
One can calculate implied probability at Thunderpick, and the tool on the popular betting website shows that the bookies feel the Red Devils have just a 16.67% chance of finishing in the top four and guaranteeing Champions League qualification.
United’s Top Four Hopes
So while Carrick must hit the ground running, he has an immediate task in front of him: rejuvenating his midfield.
The 74th minute in the recent 2-2 draw against Burnley at Turf Moor told you everything about the decision the new bosses face.
Casemiro trudged off, replaced by Kobbie Mainoo, and within seconds, the rhythm shifted. Up to then, United’s build-up had been laboured—safe passes recycled endlessly between defence and midfield.
But with the young Englishman on the pitch, everything changed.
His first touch was forward, vertical, and intent.
Manuel Ugarte sensed it too, stepping higher to press Burnley’s deepest midfielder, rather than sitting off and waiting for danger to arrive.
Ten minutes of Mainoo changed what 74 minutes of Casemiro couldn’t fix.
That’s the question Carrick inherits from Ruben Amorim’s wreckage: who sits at the base of United’s midfield, and who partners them?
At Middlesbrough, Carrick built everything around Jonny Howson and Hayden Hackney—Howson, the veteran anchor who sensed danger before it emerged, Hackney, the younger progressive force who could thread passes between lines.
They weren’t spectacular individually but became essential together, playing almost every minute during Boro’s six wins from nine after Carrick’s arrival.
Now he’s got numerous options at Old Trafford, none of them comfortable.
So, which direction will the new man at the helm head in? Let’s take a look.
Ugarte-Mainoo
Manuel Ugarte and Kobbie Mainoo have barely played together, which makes assessing this partnership feel like predicting weather patterns from a single cloud.
But the theory sounds enough to get excited about.
Ugarte doesn’t do passive.
At Sporting and PSG, he averaged 4.8 tackles and interceptions per match, living in opponents’ faces, forcing errors in dangerous areas.
He’s the type who sees an opponent receiving the ball 40 yards from goal and thinks “opportunity,” rather than “let him come.”
Mainoo’s the natural complement.
He doesn’t panic when pressed, doesn’t force passes that aren’t there.
At 19, he’s already showing positional intelligence that takes most midfielders years to develop—receiving on the half-turn, scanning before the ball arrives, understanding which spaces will open if he draws a man out of position.
When Ugarte wins it high, Mainoo’s the one who makes sure United doesn’t immediately surrender it back.
But here’s where it gets sketchy. Ugarte averaged just 4.1 progressive passes per match at PSG.
Against deep blocks, when Burnley or Brentford sit with ten behind the ball and dare United to unlock them, Ugarte offers nothing.
The creative burden falls entirely on Mainoo, who’s shown he can carry it in flashes but disappears when marking gets tighter.
At Middlesbrough, Carrick’s possession game turned “overly slow and predictable” when his midfield couldn’t progress the ball efficiently.
This partnership risks the same fate unless Mainoo develops the consistency he hasn’t shown yet.
Casemiro-Mainoo
Casemiro’s revival wasn’t supposed to happen.
By October, he looked finished—slow to react, caught upfield in transitions, bypassed by simple one-twos.”
Then the structure arrived, giving Casemiro defined zones to protect, rather than acres to cover.
His defensive numbers improved measurably because he stopped chasing lost causes and started controlling space.
Paired with Mainoo, the balance works.
Casemiro anchors, reading where danger will emerge, rather than sprinting to where it already has.
That frees Mainoo to position himself higher, drifting into those pockets between opposition midfield and defence where his dribbling and incisive passing become most dangerous.
At Middlesbrough, Carrick’s 4-2-3-1 morphed into a 3-2-5 in possession, with one fullback advancing and the other tucking into a back three.
That works when your deepest midfielder can drop into the defensive line during build-up, creating numerical superiority against the opposition’s front line.
Casemiro does that instinctively, but does he still have enough gas in the tank to deliver it now?
Casemiro-Ugarte
On paper, this South American midfield partnership is defensive overkill.
In reality, it might be Carrick’s emergency option when facing elite attacking sides.
Both players operate best as the deepest midfielder—the one who sits, screens, and senses danger.
Pairing them forces one to step out of comfort, which should mean chaos.
Against City on Saturday, or Liverpool’s front three, this pairing creates a nearly impenetrable central block.
Casemiro’s positioning intelligence, combined with Ugarte’s aggressive pressing, could suffocate the central spaces elite teams need to operate.
Except that United doesn’t have the creative “others” to compensate.
Middlesbrough scored prolifically under Carrick because his double pivots could progress possession efficiently, creating those 3-2-5 attacking shapes that overwhelmed Championship defences.
When Howson and Hackney couldn’t play forward, Boro became predictable and toothless.
Casemiro and Ugarte together may well trigger the same problems.
