The Premier League outlawed third-party ownership of players in 2007.
We need to be satisfied that any player joining a Premier League club has no third-party interests in his registration rights in order for him to be formally registered.
We believe that the practice threatens the integrity of competitions, reduces the flow of transfer income into the sport and has the potential to exert external influence on player transfer decisions.
A club need to own 100 per cent of a player's registration and so-called "economic rights" cannot be split out.
