A Polish club’s State aid complaint could fill gaps in EU case law on municipal funding to football

With the World Cup now behind us, it is time to shift attention from the pitch to the boardroom – and to a question that refuses to go away: when does public money for football clubs cross the line into unlawful State aid?

The latest flashpoint is a complaint announced by Wisła Kraków, a privately owned Polish club, against municipally funded rival Śląsk Wrocław. The European Commission (Commission) and the Court of Justice of the European Union (CJEU) have both weighed in on public support to football clubs before, and related concerns are now surfacing under the EU Foreign Subsidies Regulation (FSR). Yet despite a growing body of decisions and judgments, several key questions remain open – and the Wisła Kraków allegations do not slot neatly into any existing template. If the Commission picks up the case, its ruling could shed light on two areas that could benefit from clarity: when exactly a public shareholder’s investment counts as being on “market economy” terms, and what it takes to prove a selective advantage. Regardless of the outcome, football clubs and local authorities across the EU should take note: scrutiny is intensifying.

Practical takeaways for clubs and their owners

For clubs: Document every transaction meticulously. Clubs receiving public funding should ensure the terms could survive a comparison to what a private investor would offer. Privately funded clubs weighing a State aid complaint should brace for a long fight – but as Wisła Kraków shows, competition tools can be a powerful instrument outside traditional sport rivalry.

For municipalities: Treat every financial commitment to a football club as though it will face MEOP scrutiny. Keep valuation reports, board minutes and commercial analysis on file. Capital injections, debt waivers and guarantees all attract attention – get specialist State aid advice before extending support.

For investors: The enforcement landscape is shifting. State aid exposure can mean recovery orders, reputational damage and years of litigation. Factor these risks into your due diligence when considering opportunities in European football.

Wisła Kraków’s complaint against Śląsk Wrocław

Wisła Kraków has announced plans to file a formal complaint with the Commission alleging that rival club Śląsk Wrocław received unlawful municipal funding. The two clubs sit on opposite sides of the ownership divide: Śląsk Wrocław is almost entirely owned by the Municipality of Wrocław, while Wisła Kraków is privately held. Wisła’s president, Jarosław Królewski, has called on other privately funded clubs to join the initiative, and Wojciech Kwiecień, owner of Wieczysta Kraków, has indicated support. Wisła has also flagged a possible referral to UEFA and FIFA for breach of fair-competition principles. At the time of publication, it remains unclear whether this State aid complaint has been formally lodged.

Media reports indicate that the Municipality of Wrocław committed around PLN 40 million (approximately  €10 million) to Śląsk Wrocław in 2026 alone. This reportedly comprised a PLN 10 million (approximately  €2.5 million) share-capital increase authorised by the Mayor’s executive order in January 2026, plus a further PLN 30 million (approximately €7 million) approved by the municipal council. Broader estimates suggest municipal funding may have exceeded PLN 150 million (approximately  €35 million) in recent years – with some reports putting the decade-long total even higher.

Why does any of this matter? Because professional football is an economic activity – full stop. The CJEU settled that point long ago, and the Commission’s decisional practice, including cases such as Real Madrid, confirms it. Public funding of sports may serve legitimate policy goals, but when it gives a club an edge over privately funded rivals, it can amount to unlawful State aid. Wisła Kraków’s complaint is part of a broader trend: clubs are increasingly turning to competition law to challenge what they see as an uneven playing field.

What the case law tells us – and what it doesn’t

Commission decisions and CJEU rulings offer useful guideposts, but they are not a manual. Every case turns on its own facts, and several analytical gaps persist. Still, three types of support have attracted the most attention: municipal measures (capital injections, asset deals, debt write-offs), State guarantees and tax breaks.

Municipal support measures 

The Real Madrid saga (SA.33754) is the headline case. The General Court (GC) overturned the Commission’s original 2016 decision after finding flaws in its land-valuation analysis. On remand, the Commission applied the “market economy operator principle” (MEOP) and concluded that the Madrid City Council had, in fact, behaved as a rational private investor would – meaning no State aid was found to be transferred. The bottom line? A public shareholder can transfer funds to its club without triggering State aid rules, provided it can show that a private investor would have done the same deal under the same terms.

Despite different circumstances, the same principle was also applied in the Dutch cases. In 2016, the Commission reviewed municipal support to Den Bosch, MVV, NEC and Willem II – clubs in financial distress that had received asset purchases, debt waivers, rent cuts and other help. The measures were assessed under the rescue-and-restructuring guidelines and were cleared. A separate probe into PSV Eindhoven’s sale-and-leaseback arrangement reached the same result: because the municipality acted as a prudent private investor would, no aid was found. The message for local authorities is therefore clear: you can support your club, but only on arm’s-length terms.

State guarantees 

The Valencia case (SA.36387) tackled guarantees. The GC found that the Commission had misapplied its own Guarantee Notice when assessing backing provided by the Valencia Institute of Finance to Valencia, Hercules and Elche. The CJEU upheld the annulment of Commission’s decision on appeal, ruling that financial distress alone does not mean there is no market benchmark. In other words, even guarantees for struggling clubs must be tested against real-world comparators – not worst-case assumptions.

Tax measures 

Tax rules can also cause problems to sport clubs. In Barcelona (SA.29769), the Commission decided that FC Barcelona, Real Madrid, Athletic Bilbao and Atlético Osasuna had enjoyed a preferential corporate-tax regime by keeping their non-profit status while other clubs were forced to convert into public limited companies. Recovery was ordered. But the GC annulled the Commission’s decision, holding that the Commission had not proved a net advantage once all relevant tax rules were factored in. By doing so, the court has shown that identifying a favourable rule is only half the battle – regulators must show that the beneficiary actually came out ahead overall.

Foreign subsidies: a new front

State support to sport clubs raises concerns not only under the State aid regime. The EU’s FSR, which began applying in July 2023, has opened a parallel avenue for challenges. By way of example, in May 2023, Royal Excelsior Virton filed what appears to be the first informal complaint under the then-new FSR regime, claiming that Belgian club SK Lommel received a €16.8 million capital injection from a parent company ultimately controlled by the Emirate of Abu Dhabi. 

This shows an emerging pattern according to which clubs are weaponising competition rules to challenge rivals they see as unfairly funded.

What happens next – and why it matters

The Wisła Kraków allegations are not a carbon copy of any past case. Existing precedents offer guidance, but not a blueprint. That said, general State aid principles apply also to this case. The Commission’s assessment will almost certainly focus on the MEOP: did the Municipality of Wrocław behave as a private investor would? The Dutch and Spanish cases provide useful reference points, but the outcome will hinge on the specific facts and evidence.

The stakes are high. If the Commission concludes that Śląsk Wrocław received incompatible State aid, Poland will have to recover the financing. A negative finding could also prompt municipalities across Poland and beyond to rethink how they fund their local (not only football) clubs.

One procedural point is worth noting. Under the Procedural Regulation, when the Commission receives a well-reasoned complaint from an interested party, it must act. If it decides not to open a formal investigation, it has to explain why – and that decision can be challenged before the EU courts.
