The Brazilian frontman became the world's most expensive player following his £200m move from Barcelona in the summer, leading Emery to suggest that the 25-year-old now has the perfect conditions to reach the pinnacle of his career in club football.
"Neymar is a great player, one of the best in the world,' Emery told reporters.
"However, he is normal with the others in the dressing room and when he works. All of the other players are great and they are happy that a player like Neymar is at PSG. That is something we all wanted.
"We want to develop along with Neymar and to help him to become the best player in the world. We will work towards that for him and he will work towards that for us. Together, we will become an even greater team."
Neymar got on the scoresheet and also set one up during his Ligue 1 debut for PSG against Guingamp.
