The Brazil international, signed for a world-record €222million from Barcelona, was presented to PSG fans prior to Saturday's 2-0 win over newly promoted Amiens at the Parc des Princes, which opened their Ligue 1 season.
The 25-year-old Brazil forward, who will be presented to fans on Saturday, is committed to PSG until June 2022, the club said in a statement.
Fans incensed by Neymar's mega move to the Paris Saint Germain posted videos on Twitter dousing Barcelona jersey's with Neymar 11 and setting it alight.
3 - Without at least one MSN member, Barcelona have averaged three goals a game, compared to a slightly lower 2.8 goals per game with Messi, Neymar and Suarez all playing.
PSG are away to Guingamp next Sunday, a match that could see Neymar make his debut for the club after he was unable to face Amiens due to delays with his paperwork.
Mourinho has presided over his club's two record signings in Romelu Lukaku and Paul Pogba, the latter being the world's most expensive player before the Neymar transfer. I have played four seasons in Europe and I feel ready to take the challenge.
The Brazil international will be unveiled by the club on Friday, while there have even been reports that he might have his own parade in Paris. I want to thank Barca, their president, supporters, players, for everything they have done.
I think it's expensive the fact now you are going to have more players of 100 million and you are going to have more players of 80 million and more players of 60 million and I think that's the problem because Neymar is one of the best players in the world. Javier Tebas, head of La Liga had earlier said that PSG were engaged in "financial doping" and the Spanish body would also complain to UEFA.
A source from Spain's La Liga said earlier on Thursday that the league had rejected the payment of the clause to them after Neymar's lawyers visited its headquarters in Madrid to try to settle the transfer and pay the fee.
