Juventus chief Fabio Paratici has confirmed that there is uncertainty over a new deal for Paulo Dybala, amid speculation of where the Argentine's future lies.
Manchester United are among the clubs interested in Dybala's signature, with Juve keen to avoid losing their asset on a free transfer next summer.
Dybala is about to enter the final year of his contract with Juve after joining the club, where he has made 246 appearances for the Old Lady and is one shy of a century of goals, in 2015.
Speaking to Sky Sports News, Paratici said: "We talk to his agent every week, but we can't forget the moment we are all experiencing, even as a company.
"In September we went back to negativity and we haven't gotten out of it yet, we have to be careful with every move we make, and that's not just for football.
"Nobody can decide now what to do for the next one, two, three years. We must be very careful."
Juve have experienced a difficult season under Andrea Pirlo, with the champions currently sitting third in Serie A and on track to lose their nine-year title reign.
