Neymar can make his Paris St-Germain debut after French football authorities received clearance following his £200m world record move from Barcelona, reports BBC Sport.
The 25-year-old forward can play for the Ligue 1 side at Guingamp on Sunday.
The holdup was down to a delay in the arrival of the Brazilian player's international transfer certificate from Spanish football authorities.
At a pre-match news conference, PSG boss Unai Emery said Neymar was "physically ready to start" the game.
