Manchester City have hit out at claims they broke Financial Fair Play laws.
German tabloid Der Spiegel claimed on Friday that leaked documents showed the reigning Premier League champions "systematically violated FFP rules for years" along with another top European club, and with the knowledge of a top UEFA official.
In a statement issued to Sky Sports News, City say they are not commenting on the materials in question and suggested the club may have either been hacked or had documents stolen.
"We will not be providing any comment on out of context materials purportedly hacked or stolen from City Football Group and Manchester City personnel and associated people," the club said. "The attempt to damage the club's reputation is organised and clear."
