Every January conversation at Manchester United starts with arrivals — and the January window plan on this site sets out the positions the club needs to strengthen. But rebuilds are funded as much as they are bought. United’s squad carries players whose value, wages or simple lack of minutes make them the natural other half of the window’s business, and a club trying to reshape itself under Michael Carrick cannot ignore the selling side of the ledger. To be clear about what follows: this is an argument, not a claim. There are no “sources” here and no invented fees — just the five cases, honestly weighed, that United’s decision-makers will be debating themselves.
1. Joshua Zirkzee — the Obvious One
We have made the case for Zirkzee’s January exit in detail before, and it remains the simplest argument on this list. Zirkzee is a talented footballer in the wrong film: a link-up forward in a front line that has since been rebuilt around Matheus Cunha’s roaming and Benjamin Sesko’s penalty-box presence, with Bryan Mbeumo taking the right-sided minutes. The Dutchman has drifted to the edge of the matchday picture, and players in that position lose value with every month they sit. A January move — permanent, or a loan with an obligation built in — serves everyone: the player restarts his career, United free a forward slot and wages, and the rebuild gains room to breathe. The only argument against is depth, and depth you never use is not depth at all.
2. Harry Maguire — the Senior Defender Debate
This one hurts, which is why it belongs on the list. Maguire has rebuilt his United standing the hard way, and his aerial power in both boxes — a genuine weapon at attacking set pieces and a safety net defending them — makes him a difficult player to lose mid-season, especially with the back three already reshuffling weekly and Lisandro Martinez’s suspension showing how thin the cover runs. But every rebuild reaches the point where it must ask hard questions about its senior players: their place in the wage structure, their years, and whether the system being built actually suits them. Carrick’s higher defensive line asks different things of its centre-backs than the low blocks Maguire has mastered. Our honest view: January is the wrong moment, because buyers for players like Maguire arrive in the summer, and United need him until May. But the debate itself is legitimate — and the summer version of this list may well start with his name.
3. The Goalkeeper Room — an Honest Piece of Arithmetic
Not a headline name, but a real one. A squad cannot carry senior goalkeepers who never play, and with Senne Lammens established as the No.1 and young keepers developing behind him, the department behind the Belgian is exactly the kind of quiet area where January business gets done. A loan for a developing keeper is development; a permanent departure for a senior deputy who wants first-team football is housekeeping that frees wages and a squad place for positions Carrick actually uses. Nobody writes songs about deals like this. They are, however, how well-run windows actually work — and this rebuild needs a few boring, sensible sales as much as it needs one exciting arrival.
4. Manuel Ugarte — the Sale That Has to Wait
Ugarte belongs on this list precisely because he cannot be on it. A midfielder bought for energy and ball-winning, he is out until 2027 with a serious injury — which means no January buyer is paying serious money for him, and United’s only real options are patience and rehabilitation. He illustrates the rebuild’s central frustration: one of the squad’s most sellable profiles, a player whose strengths the league values, is locked in the treatment room while the midfield he was signed for struggles without him. When Ugarte returns, a decision will come — his style is a genuine question in Carrick’s more technical pivot — but January will pass with the question unanswered. Filing him here is a reminder that funding a rebuild is not only about choosing who to sell. Sometimes it is about who you cannot.
5. Marcus Rashford — the Name Above All Others
And finally, the debate that dwarfs the rest: Marcus Rashford’s United future, which we have weighed in full on this site. The accounting case is cold and simple — an academy product represents almost pure profit in the modern financial rules, the kind of sale that can fund an entire window — and the football case is genuinely complicated by his hip injury, which rules January out in any case and pushes every decision towards the summer. That timing clarity is, in a way, a mercy: it gives United six months of evidence. A fit Rashford, playing in a system built to use runners in behind, is worth more to this team than his fee would be. An unfit or peripheral one becomes the strongest argument the accountants have. Nothing in January changes that equation — but January is when the club will quietly decide what it wants the summer answer to be. Everything else on this list is business. This one is identity.
