If I wanted to turn this sentence written in the active voice: "People believe he may be fired", to one with Personal passive structure, how should it sound like at the end? He is believed to ... 1) be likely fired; 2) may be fired;

3. The whole sentence should be "he is expected to be fired".

Please advise which one is grammatically correct and natural, if none - I would appreciate suggestions. Thank you!
