The French FA still haven't received the necessary documents to process the Brazilian's inscription, which should be lodged before Thursday.
Paris Saint-Germain face Guingamp on Sunday and the Parisians are hoping to see £198m world-record transfer Neymar play for the first time for Emery's side.
The signing was made official last Thursday, but the international transfer certificate is missing. The Spanish FA has up to seven days to send the paperwork once the transfer is formalized, which means they have until tomorrow.
The reason why Barcelona haven't handed over the ITC is simple: the Catalans received a cheque, but they still haven't received the payment of 222 million euros stated on Neymar's release clause.
This information also gives an idea as to why Barcelona have operated so slowly in the current tarnsfer window.
The crowd at the Camp Nou want replacements to fill in for the Brazilian star, but the truth is that, having received no money, Barcelona cannot pay the multi-million fees expected from them.
The Catalan club hope to deposit the cheque in the coming days and Neymar would be able to make his debut for PSG this weekend. The Parisian side will receive all the documents once the payment is made effective.
