The Red Devils have recently overspent on a number of high-profile acquisitions.

According to a Uefa analysis, Manchester United’s roster at the conclusion of the previous season was the most expensively put together on record.

At the end of the 2023 fiscal year, the Red Devils’ roster total transfer fees costed €1.42 billion (£1.21 billion), surpassing Real Madrid’s 2020 record of €1.33 billion.

After 2022–2023—the United team consisted of Brazilian winger Antony, who cost £82 million (€96 million), England defender Harry Maguire, who cost £80 million (€93.5 million), Jadon Sancho, who cost £73 million (€85 million), and Casemiro, a midfielder from Brazil, who cost £60 million (€70 million).

Rasmus Hojlund, Mason Mount, and Andre Onana, among other newcomers from last summer, are not included in the numbers.

Further recruits last summer such as Mason Mount, Andre Onana and Rasmus Hojlund are not counted within the figures.

Uefa’s European Club Finance and Investment Landscape report found three other clubs’ squads – Manchester City, Chelsea and Real Madrid – cost more than one billion euros in transfer fees in their most recently disclosed financial year-end figures. Chelsea’s most recent figures go up to the year-end June 30, 2022, and therefore do not include their heavy spending in the summer of that year or the January 2023 window.

United have become one of 15 English top-flight clubs recognised within the report as being part of a multi-club investment group, with the purchase of a 25% stake by Ineos founder Sir Jim Ratcliffe almost complete. Ineos also holds majority stakes in French side Nice and Swiss club Lausanne.

In all, 105 top-division European clubs (13% of the total number) have a cross-investment relationship with one or more other clubs, the report found.

There were 31 purchases of majority stakes and seven purchases of minority stakes in 2023 by groups holding a stake in at least one other European club, according to the report.

However, less than one transfer per club on average is actually executed within the same multi-club structure, the report found.

As the size of multi-club investment groups has increased, that proportion has even decreased (0.6 transfers per club in 2023 compared to 0.8 in 2021), suggesting the multi-club investment trend is not entirely driven by player transfer considerations.

Andrea Traverso, Uefa’s director of financial sustainability and research, said: “More than 300 clubs are part of multi-club investment groups, leading to an increased risk of seeing two clubs with the same owner or investor facing each other in the same competition, creating potential integrity risks at the European level.

“The current context demands strict enforcement of cost control regulations and more harmonisation of financial rules between leagues. This is paramount to limit overspending, ‘creative finance’, and rules circumvention.

“As long as differences on key regulatory matters continue between leagues, inflationary tensions will persist, contributing to imbalances and instability.”

Elsewhere, the report found spending on player wages dropped by 1.1% among the clubs with the 20 largest player wage bills, with United spending 88m euros (£75m) less on player wages in 2023 compared to the year before. Barcelona and City had large increases in player wages spending — 158m euros and 68m euros (£134.8m and £58m) respectively.
