The French FA confirm the receipt of the International Transfer Certificate of Neymar sent by the Spanish Federation.
The 25-year-old made a world-record €222 million move from Barcelona to PSG last week but was unable to play because final details of his registration had not been completed.
So long as the document has been verified by the French FA (FFF) and League (LFP) by midnight on Saturday, which should prove a formality, Neymar will be able to feature in Brittany the following day.
He was in the spotlight on Friday as he participated in his first PSG training session open to the media since making his huge move, and it is anticipated that he will go straight into Unai Emery's starting XI at a ground where PSG have won only one of their previous five visits.
