MADRID (AP) — A group of European media outlets has published what it claims are details of tax arrangements made by several top soccer players and coaches, including Real Madrid forward Cristiano Ronaldo, Manchester United manager Jose Mourinho and Arsenal midfielder Mesut Ozil.

The news outlets, which include German weekly Der Spiegel and Spanish daily El Mundo, cite documents provided by the website Football Leaks, which has in the past claimed that some players and coaches made transactions that could suggest financial impropriety.

The group, which goes by the name European Investigative Collaborations, said Friday it plans to release further reports in the coming days and weeks.

The company of Ronaldo's and Mourinho's agent, Jorge Mendes, released a statement denying any wrongdoing by his clients.
