The 26-year-old Ivorian, who signed for the club from Marseille in 2016, said he heard about his admission in the media.
This has left the former Evian wing-back in a scathing mood, and has heavily criticised his club, who he also said refused to let him leave during the transfer window.
Speaking to L’Equipe, the player said: “There is one real problem in all of this, and that is that I learned in the media. It is unbelievable.
“There are certain boundaries. It gets to a point where you can’t keep quiet anymore. I am being treated like an animal.”
He added: “I am not happy. Having to train during the week, to just sit on my sofa during the weekend is horrible.
“It is not because I get a monthly salary that I should just accept this. Otherwise that would mean that I really don’t care.
“It has been two months since I have been prevented from doing the job that I love, without any explanation. I can’t go on like this.”
He added that he intends to leave as soon as possible.
“I have to leave. Either on loan or permanently. I want to rediscover my hunger for competition. I have been ready since last December, and I can’t wait anymore.
“The craziest thing in all this, is that clubs made offers to Watford to loan me, but the club refused them.”
