"He's physically ready to play the whole ninety minutes", PSG coach Unai Emery told AFP.
PSG wanted Neymar to start the season at the Parc des Princes but his debut was delayed because of the paperwork issues.
With worldwide transfer documents finally received by the French Football Federation from their Spanish counterparts, the world's most expensive footballer is primed for a first appearance with his new team.
The 18-year-old wonderkid's move means he is set to play alongside record-breaker Neymar and Edison Cavani in one of the most exciting front lines in world football.
The French Football Federation (FFF) received Neymar's transfer certificate on Friday and the Brazil global is now available to play for PSG for the first time.
FFF president Noel Le Graet said another reason for the delay could be the current turmoil within the Spanish federation.
"The federation is in contact with our Spanish counterparts".
It appears those conspiracy theories were all for naught, however, as the paperwork came through in time for Neymar to suit up on Sunday.
The bank problem holding up Neymar's Paris Saint-Germain registration has been cleared and the Brazil skipper should be free to make his debut on Sunday against Guingamp, NAIJ.com understands.
"Neymar will start on the left at the cost of Pastore", the article claimed.
The young French striker Kilian Mbappe will soon become a player "PSG".
Local reports say he has settled quickly, helped by the presence of four other Brazilians in PSG's squad.
Although the main goal for the capital club is to finally challenge for the Champions League crown, their first task this term will be to retake the Ligue 1 title from Monaco.
