NYON, Switzerland — European soccer leaders want to cap fees to player agents they believe are “disproportionately” well paid and whose quality of work is dropping.

UEFA proposes a “reasonable, proportionate cap on fees” for player transfers within Europe after meeting with representatives from clubs, leagues, and players’ unions.

Citing the risk of “economic exploitation of young players, fraud, corruption, and money laundering,” UEFA says European lawmakers can help address illegal practices.

UEFA says FIFA’s attempts in 2015 to reform monitoring of agents and intermediaries “failed to address serious concerns.”

Clubs and players now get poorer service, UEFA says, while more agents working in the industry have driven demand to recruit even younger players.

Last week, UEFA’s annual study of European club finances described rising commissions paid to agents as “eye-watering.”
