Chelsea target Alex Sandro is the subject of a “substantial offer” from an unnamed club and Juventus insist they will not stand in the left-back’s way if he wishes to leave Turin.
Reports suggest the Bianconeri have received a bid over double the 26 million euro (£23m) fee they paid Porto two years ago for the Brazilian.
It was Blues manager Antonio Conte who signed Sandro, who has won back-to-back league and cup doubles at the Juventus Stadium, and they could be reunited this summer.
Juve are keen to hang on to Sandro – who would provide competition for Marcos Alonso and Cesar Azpilicueta at Stamford Bridge – but will allow him to depart if he wants to.
Chief executive and general manager Giuseppe Marotta told Corriere dello Sport: “A substantial offer has arrived.
“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.”
“We don’t keep anyone against their will, but at the moment there are no such situations and I hope nobody will leave.”
Meanwhile, Czech Republic forward Patrik Schick is undergoing a medical at Juventus ahead of a proposed move from Sampdoria.
The 21-year-old, currently part of the Czech squad for the European Under-21 Championship, has been given permission to travel from Poland to Turin with a view to finalising a transfer worth a reported 25million euros (£22million).
Serie A champions Juve confirmed on their website on Thursday morning that Schick had checked in for his medical at around 0900 CET, and added: “A formal confirmation of the move is expected later in the afternoon.”
Schick joined Samp from Sparta Prague last summer and scored against Juve on his first start, finishing the season with 13 goals in all club competitions. He has won five senior caps and scored one goal.
He was the top scorer as the Czech under-21 team qualified for Euro 2017 top of Group One, netting 10 goals in nine games. They face Denmark on Saturday in their final Group C match, having lost 2-0 to Germany in their opener before toppling Italy 3-1 on Wednesday.
