Paris St Germain president Nasser Al-Khelaifi is "200pc" certain Kylian Mbappe will remain with the club but appears to have questioned the commitment of Neymar.
The world's two most expensive footballers have been heavily linked with moves away from the Ligue 1 champions this summer. Al-Khelaifi is no longer willing to tolerate players acting like "stars" at Parc des Princes and says "nobody forced" Brazil forward Neymar to sign from Barcelona for £198million in 2017.
But he is adamant France World Cup winner Mbappe, who initially joined on loan from Monaco two years ago before moving permanently for £116million last summer, will stay in Paris.
"I want players proud to wear our jersey, not players who do the job when it suits them," Al-Khelaifi was quoted as saying an interview which will be published in full today.
"And if they do not agree, the doors are open. Ciao. I do not want to see stars any more."
Speaking about Mbappe, he said: "Will he still be at PSG next year? I am not 100pc sure, but 200pc!
Asked about Neymar, who, like Mbappe, has a contacted until 2022, Al-Khelaifi added: "I want players willing to give everything to defend the honour of the jersey and to join the club project. The priority now is total membership of our project. Nobody forced him to sign here. Nobody pushed him. He came knowingly."
