Juventus' general manager Beppe Marotta says that Alex Sandro can leave this summer if he is no longer happy, and confirmed a suitable bid has been received.
Chelsea are reported to have made that offer and Marotta says that it matches their expectations, which is why the left-back could be on his way out of the club after just two years in Italy. However, Marotta added that the former Porto player has not yet asked to leave, so a transfer is not a formality.
"We have already received a suitable offer," Marotta told Sky Sport Italia. "We have no intention of selling anybody, but if a player decides he wants to leave, which has happened to us in recent years, then in the end they have got to leave because it is of no use to anybody to keep hold of a player against their wishes.
"But at the moment, there is no situation like that and we still hope that nobody leaves. The transfer market has not really opened so we will be able to be more concrete in the coming weeks. We have a group of 25 players who have already won, and we want to confirm them."
Juventus may be forced to act quickly if FIFA's investigations into the sale of Paul Pogba to Manchester United lead to any disciplinary action, such as a transfer ban, although Marotta says that is not something they expect to happen.
He says that the Serie A club did everything according to the rules, and they therefore do not fear any sanctions as they collaborate with FIFA in their investigation.
"It's a transfer with big numbers which could give rise to ambiguity which does not reflect the truth," he said. "It's normal that there is an investigation to erase any possible doubt, but we acted with respect of the rules and regulations -- we have just been sent some questions.
"The truth is a huge sum was earned and that a percentage was received by one of the people involved. We know the fiscal rules and we are super serene. We are confident there will not be any disciplinary action."
