The president of the French league (LFP) Didier Quillot says the Spanish Federation (RFEF) have still not sent Neymar's international clearance.
In quotes to beIN Sports, Quillot said that if things do not progress they will have no option but to ask FIFA to get involved.
According to the LFP, Paris Saint-Germain requested the clearance once they had paid the 222 million euro buyout clause in Neymar's contract on Thursday.
That same night, la Liga sent the documents to the RFEF, but didn't get an answer, which is not strange because they have a week to send them.
If within that time frame, they're still not in France, that's when complaints can be filed.
