The tricky winger, who can also play as a striker, has been linked with a move away from Turin for the past few months, with Premier League side Arsenal touted as potential suitors.
And club president Urbano Cairo has revealed that the 27-year-old Italian has expressed his desire to seek pastures new this transfer window.
"Cerci's sale is still possible and he has asked to leave," Cairo is quoted as telling Mediaset Premium.
"There are still four days left in the transfer window, so we will see what happens.
"I've given my word that we'll sell him if an adequate offer arrives.
"Arsenal? There are several options."
His manager Giampiero Ventura admitted that Cerci is not in the right frame of mind to feature for Il Toro, and is unsure what the future holds.
"Currently, Cerci does not have the right head to play," Ventura told a press conference.
"We wil wait for the end of the market and see."
