Barcelona coach Xavi cannot guarantee keeping hold of Ousmane Dembele.
Outstanding in preseason, Dembele is playing with a 50m buyout clause in his contract this summer.
PSG and Newcastle have been linked with the France international.
And Xavi concedes: "We'll see, in the transfer market you never know. I see him happy and satisfied, if there is anything I think he'll tell us the problem, but basically he's with us and he's happy.
"We can't control the transfer market, there's a clause and these are things for the player to decide on. I think he's settled in well here since he arrived. He has always told us that he is happy, that he is part of the family and that he knows he can make a difference. But as said, anything can happen in the transfer market."
