Spanish prosecutors have requested that Neymar is tried for fraud in relation to his big-money move to Barcelona from Santos in 2013.
The Catalan giants announced that they paid a transfer fee of €57million for the Brazil captain, with Santos receiving €17m of that and Neymar s parents receiving the remainder.
However, a Brazilian investment fund that owned 40 per cent of the player s rights claims it was not paid the money it was owed.
Attorney Jose Perals of Spain s High Court has asked for an indictment for both Neymar and his father in the case.
An investigation claims the transfer fee for Neymar was much higher than reported at €83m and that the details were hidden from the public.
Both Neymar and Barcelona have denied any wrongdoing.
