Neymar's debut for PSG could be delayed again

Paris - Neymar was unveiled to the PSG fans on Saturday

It's been nearly a week since Neymar landed in Paris, and the world's most expensive player still can't play for his new club in the French league. 
Neymar's world-record 222 million euros ($262 million) transfer from Barcelona to Paris Saint-Germain was completed last week, but the Brazil international has yet to be granted permission to play. 
PSG wanted Neymar to start the season at the Parc des Princes last week against Amiens but his debut was delayed because his international transfer certificate (ITC) had not been received by the French league on time. 
Neymar was unveiled to the PSG fans on Saturday, but watched from the stands as his new team started its league campaign with a 2-0 win. 
The former Santos player was then expected to play on Sunday night at Guingamp at the 18,000-capacity Stade du Roudourou, but PSG fans might have to wait a bit longer to see the star in action. 
The French league said in an email to The Associated Press on Thursday that it had not received the document needed from the Spanish federation. It added the deadline for receiving the document was midnight local time. 
The French league added that it "does not understand" why its Spanish counterpart "refuses to accept the payment for the buyout clause for Neymar." There has been speculation in France that Barcelona slowed down the whole process as a retaliation measure against PSG after the French league club lured one of their its players out of the Camp Nou. 
According to French newspaper L'Equipe, PSG is unlikely to ask Fifa to rule on the issue because it could slow down proceedings further. The club did not immediately answer a message from The Associated Press seeking comments. 
Asked about his views on the issue after the Amiens game, PSG coach Unai Emery said last week he was not sure "Spain did everything" to ensure Neymar would be cleared to play for PSG without delay.
