A club can have the money, agree terms with a player, and still need to sell before it can sign them. The problem isn’t always cash in the bank or the owner’s willingness to spend. Sometimes what’s missing is room under UEFA’s financial rules.
Since the 2025/26 season, clubs competing in European competitions have had to comply with the so-called squad cost rule. It caps squad costs at 70% of a club’s assessable revenue.
The rule didn’t fully replace the old Financial Fair Play system. Loss control shifted over to what’s now called the football earnings rule, while the squad cost rule added something that didn’t exist before: a direct link between what a club earns and what it can spend on its squad.
What a signing actually costs
The rollout was gradual. The cap started at 90% in the 2023/24 season, dropped to 80% in 2024/25, and settled at its final 70% in 2025/26.
To do the math, UEFA mainly looks at player and coaching staff wages, transfer amortization, and agent commissions. That total gets measured against the club’s adjusted revenue and the net result of its transfer activity.
That forces clubs to look at a signing as more than just its transfer fee. Wages, bonuses, agent fees and the amount the club has to book each year for the transfer all get added to the total.
In January 2023, Chelsea signed Enzo Fernández and Mykhailo Mudryk to eight-and-a-half-year contracts. Those unusually long deals also had an accounting advantage: the longer the contract, the more seasons a club could spread the transfer fee across on its books.
At the time, this had become a way for clubs to reduce the annual impact of major transfer fees. But in July 2023, UEFA introduced a five-year limit on the initial amortization period for new transfers. Clubs could still sign longer contracts where national rules allowed it, but for UEFA accounting purposes, the transfer fee could only be spread across a maximum of five years. The change was not applied retroactively to deals already in place.
Why selling matters more now
For clubs sitting close to that 70% mark, a sale can do two things at once. It frees up the departing player’s wages, and it can produce an accounting profit if the sale price is higher than the player’s remaining book value.
That headroom can then go toward a new signing. Which is why, when a club is reported to need a sale before it can buy, that doesn’t necessarily mean it’s short on cash, it’s often a regulatory need, a way to keep squad costs within the allowed percentage.
Qualifying for European competition pushes things the same way. Prize money and broadcast revenue expand a club’s spending capacity; losing that income can shrink its room to maneuver in future seasons, even if it doesn’t force an immediate sale.
The effects aren’t just theoretical anymore. In June 2026, UEFA sanctioned nine clubs for exceeding the 70% threshold during the 2025 calendar year. Strasbourg was fined a total of €25 million and Aston Villa €22.5 million, with part of both fines tied to their future financial performance.
Because their breaches were considered significant, both clubs were also hit with restrictions on registering new signings to their Champions League squad lists for the 2026/27 season, a consequence that can directly shape market planning and squad building.
A rule that opens up another debate
UEFA says the cap is meant to control spending and rein in wage and transfer inflation. The percentage, though, is the same for everyone, revenue isn’t. Clubs with bigger income streams can still spend far more on their squads than smaller ones.
The rule can help stop a club from spending itself into trouble, but it can also lock in the advantage of clubs that already have the biggest commercial and sporting revenue. Which leaves the debate open: does the squad cost rule actually make European football more balanced, or does it just protect the financial order that already exists?
The Agency Perspective
The squad cost rule changes the way a transfer needs to be evaluated. For clubs, a player’s cost can no longer be viewed simply through the transfer fee. Salary, bonuses, agent fees and amortization are all part of the same financial equation that must remain within UEFA’s established limit.
From an agent’s perspective, understanding that structure is becoming increasingly important. A club may have a genuine sporting interest in a player and even have the resources to pay the transfer fee, yet still lack the financial margin required to complete the signing at that moment. In some cases, another player may need to be sold, wages reduced or additional revenue generated first.
Having close relationships with sporting directors would get agents access to information on the budgets available for transfers and salaries. Agents have to be knowledgeable, diligent, and creative to get deals done.
This also helps explain why certain negotiations accelerate after a major sale, or why an apparently advanced transfer can suddenly stall. The issue is not always sporting or related to the selling club’s asking price. Sometimes the real limitation is how the signing will affect the club’s accounts over the following seasons.
The rule also makes contract planning increasingly important. Contract length, salary, bonuses and the overall financial structure of a deal can be just as relevant as the transfer fee when trying to find a solution that works for every party involved.
For players, this means that interest from a club needs to be understood within a broader context. Qualifying for European competition, completing an important player sale or moving a high salary off the wage bill can quickly change a club’s ability to pursue a signing.
For agents, understanding these limits provides a clearer picture of when an opportunity is genuinely available, what obstacles may affect a negotiation and when the right moment to act could be. In today’s market, knowing the player and the club remains essential, but so does understanding the financial structure that makes a transfer possible.
