Manchester United are expected to prepare a significant transfer budget as part of their plans to satisfy the demands of a new head coach, amid growing concerns over the true financial cost of another managerial change at Old Trafford.
The warning comes from football finance expert Dr Dan Plumley, who spoke exclusively to Football Insider about the “hidden costs” that often follow the dismissal of a manager and the appointment of a successor. According to Plumley, the financial impact goes far beyond severance packages and compensation clauses, extending deep into squad management, transfer strategy, and long-term wage commitments.
United are currently navigating a transitional period following the dismissal of Ruben Amorim. Club legends Michael Carrick and Ole Gunnar Solskjaer have emerged as leading candidates to take charge on an interim basis until the end of the season. At the same time, several high-profile names are being linked with the permanent role, including Crystal Palace boss Oliver Glasner and former Bayern Munich and Germany head coach Julian Nagelsmann.
The True Cost of Changing a Manager
Plumley stressed that discussions around managerial appointments often underestimate the financial ripple effect that follows a change in leadership.
“When people talk about replacing a manager, the focus is usually on compensation,” Plumley explained. “That’s the obvious, immediate cost. But in reality, that’s only part of the picture. There are a lot of hidden costs that come with a new manager inheriting a squad.”
Those costs, according to Plumley, are closely tied to how the incoming coach views the existing group of players and whether they fit his tactical philosophy. Decisions over who stays, who leaves, and who must be signed can quickly escalate into major financial commitments.
“Does the new manager want to keep the squad as it is? Does he see value in the current players? What are his transfer plans? And what does his vision look like over the medium to long term?” Plumley added. “All of these questions have serious financial implications.”
Hidden Financial Pressures Behind the Scenes
Plumley highlighted that Manchester United’s financial obligations stretch across multiple areas, including player wages, contract amortisation, existing long-term deals, agent fees for new signings, and additional transfer costs.
“All of that feeds into the squad cost ratio monitored by UEFA, and the Premier League keeps a very close eye on it as well,” he said. “United are still operating within acceptable limits, but there is definitely reason to be cautious. The appointment of a new manager brings major financial decisions with it.”
With UEFA’s financial sustainability regulations tightening and domestic scrutiny increasing, United cannot afford unchecked spending, even for a club of their global stature. Each major signing impacts not only immediate cash flow but also long-term accounting through amortised transfer fees and escalating wage bills.
Plumley noted that if United opt for a manager like Oliver Glasner, the Austrian coach would almost certainly demand assurances over transfer backing.
“United spent heavily in the summer, and there’s a strong chance they’ll have to do it again to keep the next manager happy,” Plumley said. “That’s exactly what I mean by hidden or long-term costs that come with changing a manager at this stage.”
Balancing Ambition With Financial Reality
Manchester United’s recent history has shown that managerial changes often lead to expensive rebuilds, with each new coach seeking players suited to their system. This cycle has left the club with a bloated squad, overlapping profiles, and contracts signed under different sporting visions.
While appointing an elite manager could help restore stability and competitiveness, it also carries the risk of further financial strain if expectations are not carefully managed. The club’s hierarchy must now strike a delicate balance between ambition on the pitch and sustainability off it.
Julian Nagelsmann, for instance, is known for his progressive tactics and strong views on squad composition. Securing his services would likely require not only a substantial salary package but also a commitment to invest in younger, technically versatile players—another potential drain on resources.
Kobbie Mainoo’s Future Under the Spotlight
Beyond finances, the arrival of a new manager could significantly impact the careers of several players, particularly young talents like Kobbie Mainoo.
The 20-year-old midfielder found his opportunities limited under Ruben Amorim, prompting speculation that he had considered a move elsewhere in search of regular playing time. Despite the uncertainty, Manchester United have no intention of selling Mainoo, viewing him as a long-term asset.
With Amorim now gone, Mainoo sees a fresh opportunity to establish himself under the next head coach. A new managerial philosophy could transform his role at Old Trafford, potentially turning him into a key figure rather than a peripheral option.
Club sources suggest Mainoo is determined to fight for a place in the starting XI, and the upcoming managerial appointment could prove to be a pivotal moment in his development.
A Defining Moment for United’s Strategy
As Manchester United continue their search for stability, the next managerial decision will be about far more than results on the pitch. It will test the club’s financial discipline, long-term planning, and ability to align sporting ambition with economic reality.
Dr Dan Plumley’s warning serves as a timely reminder that replacing a manager is rarely a clean reset. Instead, it often triggers a chain reaction of costs and commitments that can shape a club’s future for years.
For United, the challenge is clear: appoint the right manager, back him wisely, and avoid repeating the costly mistakes of the past. With financial pressures mounting and expectations remaining sky-high, the margin for error has never been smaller at Old Trafford.
