According to 'EFE', UEFA sources have said that European football's governing body will analyse the details of Neymar's potential move as part of continued attempts to ensure that clubs abide by Financial Fair Play rules.
These sources claim that Neymar's move will have "an effect on the footballing economy in the years to come, but that the effect of the move cannot be pre-judged, not least because PSG could sell several players for a significant figure."
With this in mind, the organisation can only "do the calculations at the end" in order to confirm that the move respects the FFP rules that govern all European clubs. In accordance with these rules, clubs must "show losses of no more than €30m over a three-year period."
