Juventus GM Beppe Marotta concedes Alex Sandro could leave.
The fullback is being linked with a move to Chelsea.
“A substantial offer has arrived," said Marotta.
“We have no intention of selling anyone, but if a player decides to leave, as has happened in previous years, then at the end of the day he has to go, because we don't keep anyone against their will.
“But at the moment there are no such situations and I hope nobody will leave."
