The Premier League says it will investigate allegations that Manchester City broke third-party ownership and UEFA's Financial Fair Play regulations if "substantiated material" is presented.
Using documents obtained by Football Leaks, a number of media organisations have made a range of allegations against City over the past 10 days, including that the Premier League champions negotiated a watered-down punishment for failing FFP in 2014, and that the club's owner, Sheikh Mansour, has hidden millions of pounds of cash injections using Emirati club sponsors.
It was also alleged towards the end of last week that City signed an agreement with FC Nordsjaelland president Tom Vernon that would allow them to dictate the futures of West African talents to have signed for the Danish club through the Right to Dream academy.
