Juventus will reportedly launch an approach to sign Willian from Chelsea on a free transfer next summer.
The Brazilian, who joined the club in 2013, has failed to reach an agreement over a new contract with the Blues and will therefore be a free agent in June 2020.
New manager Frank Lampard has not included Willian in the starting XI for any of Chelsea's first four Premier League games, with the former midfielder using Mason Mount in the attacking midfield role instead.
According to the Daily Mail, Juventus plan to take advantage of Willian's situation and bring the 31-year-old to Turin next year.
The Old Lady has a history of completing shrewd free purchases, as seen through the arrivals of Aaron Ramsey, Adrien Rabiot and Emre Can in recent times.
Willian has made a total of 295 appearances in all competitions for the West London side, scoring 52 goals.
