Unai Emery has stated his desire to hold on to Blaise Matuidi, with Juventus looking to sign him.
The Serie A giants were looking to acquire the French midfielder as replacement for Paul Pogba.
Club president Nasser Al-Khelaifi has also said the 29-year-old will sign a new contract at the club.
“I explained last week,” Emery told reporters ahead of PSG’s trip to Monaco on Sunday.
“The president [Nasser Al-Khelaifi] said he has a contract with the club and I want him to stay here.
“I’m in a great club with great players and I want the best team. I do not want them to leave, I want them to stay with me.
“Many left: [Jean-Christophe] Bahebeck, [Benjamin] Stambouli, [Salvatore] Sirigu, [Zlatan] Ibrahimovic. We have 20 players in the group and that’s a good number.
“But I understand that for all great teams, the door is not closed and nothing is finished until August 31. For us to improve, the door must remain open and I do not close it.”
