Willian and his family received death threats on the internet.
The Brazil international has already been linked with a return to the Premier League with Fulham.
Willian asked for his contract to be terminated.
It didn't go as we expected, so we are sad not to have him anymore. We have to keep the happy ones here.
Willian played in the second leg of the Libertadores quarter-finals on Wednesday as the Brazilian side were knocked out of the competition.
"Whenever Corinthians lost and I didn't play well, my family received threats and insults on social media - my wife, my children, and recently they also started attacking my father, my sister," Willian told the Globo Esporte website.
