Just pointing to the conclusion:
In conclusion, it is sensible for UEFA to agree rules on solvency for European football clubs. But UEFA needs to tread carefully. In particular, it is important to distinguish between balance sheet and cash-flow solvency. The exclusion of non-football income may be unsustainable and subject to legal challenge. Overzealous application of the Fair Play rules generates a significant risk that the dominance of the strong clubs will be enhanced, while the financial instability of lower-division teams in national associations is not addressed. Finally, UEFA may face a challenge under EU competition law if competition in player markets is reduced.
Looks much like finance??
