PSG manager Thomas Tuchel says he "cannot guarantee" whether Adrien Rabiot will be at the club beyond January.

The Frenchman has yet to sign a new contract with PSG and will be a free agent in the summer.

Chelsea, Tottenham, Liverpool and Barcelona have expressed an interest in the midfielder. And their chances of signing the 23-year-old have seemingly increased with Tuchel's comments.

"I cannot guarantee that Adrien (Rabiot) will finish the season with us because it is still the same thing. He did not say yes to PSG. And as a result of that, everything is possible," he told reporters.

"Like you say, it was necessary and important for me, for us, to sign a number 6 for our team this summer. Now we are in winter and it is the same thing. It depends on the situations of Adrien Rabiot and Lassana Diarra. Maybe we will need them now."
