The striker has been with United for four years now and it looks like this transfer window could see him make his move.
Last season the 31 year old made 12 league appearances and even then he weighed in with Seven goals.
A year earlier he was the Premier League's equal top-scorer.
Berbatov wrote on his Facebook page. "The truth is, I love this club, but I am not going to be useful to anyone if I am not playing, and I want to play, I want to help.
"But for unknown reasons it's not going to happen, or my chances will be limited, so it's better for everyone if we say goodbye.
"If not, I am professional and I will keep doing everything I can to help my team and my team-mates, whenever I have opportunity to do so."
