Paris Saint-Germain chairman Nasser Al-Khelaifi has stated that Neymar will "2,000%" be at the club next season.
The 25-year-old became the world's most expensive player when PSG triggered the £200m release clause in his Barcelona contract in August.
Despite a fruitful return of 26 goals in 24 appearances, Neymar is rumoured to have grown unhappy with life in Paris and is reportedly pining for a move to Real Madrid.
Speaking after Saturday's 4-0 Ligue 1 win over Montpellier, in which Neymar bagged a brace, Al-Khelaifi told L'Equipe: "When I listen to the rumours, I smile because it is not true.
"We have Neymar, he is very happy here, he is happy to score. We signed five years here. It's been four months. I do not think he wants to leave.
"He is a fantastic player. There is a link between him and the fans. The link with Real? It makes me laugh when I listen to that. These are rumours. You ask me to answer rumours.
"All is well, we have a very big game against Real Madrid. It's important to focus on this game and not listen to the rumours. We do not want to enter the game of the Spanish press. Will he be there 100% next season? Not 100%, at 2,000%."
Neymar spent three weeks on trial with Real Madrid in 2006 but remained with Santos until 2013 when he sealed his switch to Camp Nou.
