LONDON (Reuters) - The information underlying the Reuters report on soccer comes from a trove of contracts, presentations, emails and other material relating to leading soccer clubs that was obtained by the German news magazine Der Spiegel. The magazine shared access to the documents with Reuters and more than a dozen other media outlets in cooperation with European Investigative Collaborations (EIC).
The material came from a source Der Spiegel identifies only as John. In response to questions relayed via Der Spiegel, John said he is Portuguese. He declined to provide further personal details, including where he currently is based or his occupation.
