The 34-year-old went on a free transfer to Corinthians last summer, but the return has been everything but pleasant for the winger who has 70 caps for the Brazilian national team since his debut in 2011.

On Friday, Willian said he would return to Europe and had terminated the contract with the club. English media has linked him to Premier League club Fulham.

"I did not come to Brazil to get threatened," Willian told reporters for the Globo Esporte.

"Whenever Corinthians lost and if sometimes I was not doing well in the game, my family received threats, and curses on social media.

"My wife, my daughters, after a while (they) also started attacking my father, and my sister."

Willian was attacked by some of the fans over poor performances as Corinthians were eliminated from two important competitions in recent weeks, despite the team enjoying second spot in the Brazilian league.

"Willian alleged private and family problems and the desire to leave Brazil. Corinthians are sorry, but respects the player's decision," Corinthians said in statement.
