Juventus president Andrea Agnelli has admitted that Paul Pogba is not a certainty to remain with the Italian champions next season.
The Turin giants already turned down a reported 80million euros offer from Barcelona for Pogba last week and also one from Manchester City of 100million euros.
When asked if Pogba was not on the market, Agnelli said to Turin sports newspaper Tuttosport: "In football everything is possible.
"I remember that some years ago we wanted to keep (Christian) Vieri at Juventus.
"The player was considered non-transferable but a few days later, Vieri was sold to Atletico Madrid.
"Hence, my players are non-transferable from September 1st."
