The luxury homes on a Spanish island and the gleaming yachts moored in Mediterranean ports were all trappings of a life well-lived.

They were also, according to the Spanish authorities, the fruits of a multimillion-dollar money laundering and tax-evasion operation controlled by one of world soccer’s most powerful soccer agents, which last month resulted in criminal indictments against the agent, Abdilgafar Fali Ramadani, and several of his associates.

According to the authorities, Ramadani was at the center of the scheme in which a group of agents connected to him were able to exploit lax regulations and hide millions of dollars in commissions by moving athletes through several so-called “ghost” clubs in Belgium, Serbia and Cyprus. By doing so, the authorities said, the agents avoided paying taxes on the payments they received for brokering the deals.

Reached by telephone, Ramadani declined to comment on the charges. His Berlin-based agency, Lian Sports, has grown to represent some of soccer’s most sought-after players.
