The Brazilian, who last week completed a world record-breaking £199million move from Barcelona, had hoped to be available for the club’s Ligue 1 opener against Amiens SC last Saturday.
But the 25-year-old wasn’t registered in time and instead had to watch his new teammates win 2-0 from the Parc des Princes stands.
According to French publication L’Equipe, Neymar may be forced to take his seat in the stands again this week due to even more paperwork hold-ups.
The news site reports that the French football federation has not yet received Neymar’s International Transfer Certificate from its Spanish counterpart.
A source has explained that Barcelona has allegedly not yet given Spain’s football federation permission to send it.
And while under FIFA rules Barcelona have 15 days from the initial request to send over the papers, they will prevent Neymar from making his debut until August 20 if they do so.
Meanwhile Neymar is considering making a formal complaint to FIFA against Barcelona, due to unpaid loyalty bonuses, according to Sky Sports.
The Brazilian reportedly feels “very bad” over the withheld payment, with the club refusing to pay a £23million bonus to his dad.
