The 25-year-old was unable to make his maiden PSG appearance in the 2-0 win over Amiens at Parc des Princes last Saturday because Barca had not confirmed that they had received the fee in full, which meant his worldwide transfer certificate (ITC) could not be granted.
However the coverage will ramp ahead of the game against Guingamp, with all eyes set to firmly be on the new most expensive player in the world.
However, he had to watch last weekend's 2-0 win over Amiens from the stands as the administrative formalities of the deal were not completed in time.
It means that Neymar could now be cleared for involvement in PSG's trip to Stade du Roudourou.
"If the French federation does not start proceedings with FIFA, we could still receive the ITC up until Saturday night", the league said.More news: Premier League 2017-18 season sees two Manchester clubs as favorites
The French league added it "does not understand" why its Spanish counterpart "refuses to accept the payment for the buyout clause for Neymar".
"The cheque has cleared and therefore puts in motion the process of the transfer", said a Barcelona club source.
Mundo Deportivo and La Gazzetta Dello Sport have reported that PSG are nearing a deal with Jorge Mendes, Mbappe's agent and the one in charge of leading the negotiations on Monaco's side, for the transfer of the youngster.
But the French Football Federation (FFF) appear confident that the saga surrounding Neymar, who cost PSG a staggering world record of 222 million euros ($264m), is near its end. Angel Maria Villar, who ran Spanish soccer since 1988, was suspended last month from the presidency for one year by Spain's top sports authority for his suspected involvement in corruption. Neymar has since returned to training with his teammates.
