Paris Saint-Germain coach Thomas Tuchel cannot guarantee Adrien Rabiot staying this month.
The France midfielder is being linked with Juventus and AC Milan.
“I don't know, it's Adrien's decision," Tuchel said.
“I explained the situation in Singapore. His contractual situation is clear, he still has one year on his contract.
“I like working with Adrien and I'm convinced he has the potential to be a top, top player for PSG.
“He's an academy player, and in my mind it's very important that we have players from Paris who came through the youth system.
“The situation is what it is though. Adrien must make a decision, he has to confirm that he wants to play for the club."
