Willian has less than three months left on his contract at Chelsea.
The winger wanted a three-year deal to continue at Stamford Bridge, but the Blues have so far not met his demands for an extension.
Willian can leave Frank Lampard’s side as a free agent in the next transfer window and the attacker has been linked with a handful of clubs across Europe.
Prior to arriving in England, the player had spells with Anzhi Makhachkala and Shakhtar Donetsk.
His former manager at the Ukrainian side, Mircea Lucescu, has given some advice to the Brazilian during an interview with TuttoJuve.com.
“He has been at Chelsea for many years and perhaps it would be time to change. The London club fell in love with his performances when they faced us in the Champions League.”
Juventus have been rumoured to be one of the destinations for Willian, while the Catalan media talked about Tottenham Hotspur’s interest in the player after Barcelona rejected an opportunity to sign him.
Speaking to Brazilian newspaper O Estado de São Paulo over the weekend, the 31-year-old stressed he will ‘give everything’ to the west London club ‘until the end’.
