PSG boss Laurent Blanc has made it clear he doesn't want to lose Marquinhos.
The Brazilian defender has been linked with Manchester United.
Blanc said: "Marquinhos has a spirit and a special mentality.
"We have done everything to keep him and we will do everything possible to extend his contract.
"It is good that as a player he can operate in different defensive roles, and let's not forget he is just 20 years old. He and Adrien Rabiot represent the future of PSG."
