Tuttosport says given the player is out of contract at Chelsea this summer, the Italian champions are 'monitoring' him, assessing whether they can make a financially sound deal.
Willian is currently with his family in Brazil during the lockdown for the coronavirus pandemic but with no movement on fresh terms at Chelsea as of yet, his future has got teams across Europe on notice.
The key for Juventus could prove to be the player's pre-existing relationship with manager Maurizo Sarri.
Just this week, Willian said: "Sarri is a good coach. I can't tell you what happened. He had an interesting tactical part, he liked a beautiful game, with the ball."
