A Spanish judge has asked Barcelona to hand over Neymar's transfer documentation following accusations that club president Sandro Rosell embezzled €40 million (£33.8m).
The Brazil international moved to Camp Nou in a €57m (£48.1m) 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 that the Blaugrana chief is guilty of stealing €40m - 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 have a case to answer.
The reigning Spanish champions have previously refused to clarify specific details regarding the money involved, highlighting a confidentiality clause supposedly inserted by one of the parties involved in the deal.
But the club insist that they are innocent of any wrongdoing and maintain that they will provide all necessary information to judge Pablo Ruz as and when required.
