The Football Association are investigating allegations that Manchester City made a payment of £200,000 to the agent of Jadon Sancho when the teenager joined the club from Watford.
German outlet Der Spiegel has published documents claiming that Sancho’s agent, Emeka Obasi, took the payment to help seal the transfer, which set City back £66,000 for the then 14-year-old winger.
They have published a number of leaked documents over recent times on City, one of which claim that the payment was hidden by claiming to hire Obasi as a club scout.
A brief City statement read: "The attempt to damage the club's reputation is organised and clear.
"We will not be providing any comment on out of context materials purported to have been hacked or stolen from City Football Group and Manchester City personnel and associated people."
FA rules state that players under the age of 16 can’t be represented by an agent while clubs are not allowed to offer financial incentives to young players until they reach the age of 16, both of which have been broken if the allegations are true.
