Revisiting “Ronaldo Economics”: A 7-Year Audit of Football’s Financial Engineering
In May 2019, I published a thesis on ResearchGate that I had written during my Masters in International Business Law for a course with Professor Jinyan Li. The paper examined how public policy and taxation dictate the migration patterns of international superstar footballers. At the time, Cristiano Ronaldo had just moved to Juventus and Lionel Messi was the centerpiece of Barcelona—both of whom have since moved on, proving the hyper-mobility of the “superstar asset.”
The core premise of the paper was that in a highly mobile, hyper-lucrative global market, top-tier footballers operate similarly to Multinational Enterprises (MNEs). Consequently, countries looking to acquire these assets to boost domestic leagues utilize the same tools used to attract MNEs: a “race to the bottom” via favorable corporate tax policies.
Looking back from the vantage point of 2026, the global football landscape provides a useful laboratory to assess how these macroeconomic and legal observations have materialized.
1. “Ronaldo Economics” Catalyst and Italy’s Reversal
Thesis Claim (2019): I argued that Italy’s flat tax on foreign income was the primary catalyst for Ronaldo’s move to Juventus, projecting that the club was positioned to generate a positive ROI from the player’s commercial draw.
The Reality: Accurate Catalyst, Failed ROI. While the tax incentive effectively facilitated the transfer, the projection of a positive ROI did not materialize as expected. The financial burden of Ronaldo’s gross wages severely strained Juventus’s finances. This strain, compounded by the pandemic, ultimately led to the Plusvalenze (capital gains) and Prisma investigations, resulting in the resignation of the Juventus board, point deductions, and a UEFA competition ban. The tax optimization strategy succeeded in relocating the asset, but it could not insulate the club’s balance sheet. The pandemic was a huge unforeseen business risk that cost Juventus dearly on the field, off the field, and in the board room.
2. Loophole as the “Industry Standard”
Thesis Claim (2019): I claimed that “the expertise of creative tax lawyers and accountants have made loopholes the norm” and that clubs would constantly innovate to bypass Financial Fair Play (FFP) and tax liabilities.
The 2026 Verdict: Confirmed via Chelsea and Technical Amortization. In 2023, Chelsea FC provided the ultimate modern proof of this “loophole culture” by signing players to unprecedented 8.5-year contracts.
- The Technical Logic: Under IFRS accounting standards, transfer fees are capitalized as intangible assets and amortized over the length of the contract.
- The Maneuver: If a player costs £100m on a standard 5-year deal, the annual accounting charge is £20m. By stretching contracts to 8.5 years (e.g., Enzo Fernández, Mykhailo Mudryk), Chelsea reduced that annual charge to roughly £11.7m.
- The Result: This creative accounting allowed the club to spend over £600m in a single year while appearing to stay within the Premier League’s Profitability and Sustainability Rules (PSR). This forced UEFA to change global regulations mid-season to cap amortization at five years.
3. Scrapping of Italy’s Growth Decree
Thesis Claim (2019): Comparing Italy’s approach to Germany’s stricter tax regime, I noted a potential drawback to preferential tax settings: “Domestic talent can suffer when they lose playing time and other developmental resources to more established foreign players.”
The Reality: Vindicated by Policy Reversal. In late 2023, the Italian government was forced to scrap the Decreto Crescita (Growth Decree). Policymakers admitted that the tax break for foreign talent made it more cost-effective to import players than to invest in domestic academies, acknowledging the negative externality on the Italian national team’s developmental pipeline that I identified years earlier.
4. Saudi Pro League Expansion
Thesis Claim (2019): “Reducing national tax liabilities of high income foreign workers may attract superstar footballers to play in those countries with favourable regimes.”
The Reality: The Ultimate Application of the MNE Model. The Saudi expansion of 2023 and 2024 provided a large-scale application of this economic principle. By utilizing a 0% income tax rate for foreign talent, Saudi Arabia successfully attracted Cristiano Ronaldo, Neymar, Karim Benzema, and N’Golo Kanté. Because players face virtually zero migration barriers post-Bosman, a zero-tax environment serves as an unbeatable competitive advantage in the global labor market.
5. Messi Precedent: Clubs as Tax Shields
Thesis Claim (2019): I observed that Lionel Messi’s 2021 contract renewal at Barcelona implicitly required the club to absorb the financial burden of his personal tax liabilities stemming from earlier convictions.
The Reality: Financial Risk Shifted to Institutions. This established a notable operational precedent where the financial liability of aggressive national tax enforcement is passed onto the employer. This effectively shifts the cost of tax prosecution onto the club’s payroll. Barcelona remains in a state of prolonged financial recovery due to the unprecedented expenditures required to appease and insulate their superstar assets.
6. “Irish Buffer” and the Limits of OECD Article 17
Thesis Claim (2019): I argued that global tax frameworks were not adequately equipped to handle image rights, specifically highlighting that Article 17 of the OECD Model Convention is too limited in scope to track modern commercial endorsements.
The Reality: Ongoing Exploitation of Regulatory Gaps. This fostered the “Irish Buffer” strategy: setting up Image Rights Companies (IRCs) in low-tax jurisdictions like Ireland (12.5%) to act as intermediaries for major global brands. The lack of a unified, global statutory definition of “image rights” remains a complex area of international tax law that facilitates significant tax gaps, a core focus of the current Premier League investigation into Manchester City.
The Ultimate Validation: The 2021 EU Parliamentary Study
In October 2021—two and a half years after my thesis was published on ResearchGate—the European Parliament’s Subcommittee on Tax Matters (FISC) published a formal commissioned study titled “Taxing professional football in the EU: A comparative and EU analysis of a sector with tax gaps.”
The 80-page EU report independently maps out the exact framework that I personally identified in 2019:
| Feature | 2019 Thesis Analysis | 2021 EU Parliamentary Study |
|---|---|---|
| Conceptual Model | Players as Multinational Enterprises (MNEs) | Formally adopts the MNE framework |
| Primary Catalyst | The 1995 Bosman Ruling | Roots analysis in the 1995 Bosman Ruling |
| Comparative Regimes | Spain’s Beckham Law & Italy’s Flat Tax | Focuses on Beckham Law & Flat Tax |
| Regulatory Gap | Critique of OECD Article 17 | Critique of OECD Article 17 |
| Evidentiary Basis | Football Leaks data & Der Spiegel | Football Leaks data & Der Spiegel |
Conclusion
The fundamental dynamics of the football transfer market extend beyond scouting and sporting merit; they are deeply tied to international tax law and legislative policy. The financial rewards for securing elite talent are so high that the intersection of accounting, image rights, and state-sponsored tax incentives will continue to influence where the world’s best players migrate. As events from the past few years demonstrate, the economic and legal patterns identified previously continue to serve as the catalyst for rapid change in the world of footy.
