A Spanish judge has asked Barcelona to hand over Neymar's transfer documentation following accusations club president Sandro Rosell embezzled 40 million euros.
Neymar moved to Camp Nou in a 57m euro transfer from Santos in July, but details relating to the final sum paid for the player and to which parties the money was eventually allocated to remain unclear.
One of Rosell's presidential opponents, Jordi Cases, claims the Blaugrana chief is guilty of stealing 40m euros - which was previously thought to have gone to the player's father by way of commission following his role in the deal.
But the Spanish High Court is set to look over all documents relating to the move before deciding whether Barcelona has a case to answer.
The reigning Liga champions have previously refused to clarify specific details regarding the money involved, after highlighting a confidentiality clause supposedly inserted by one of the parties involved in the deal.
But the club insists it is innocent of any wrongdoing and maintains it will provide all necessary information to judge Pablo Ruz as and when required.
