Steve Cooper is fighting to keep his job as Nottingham Forest boss after the thumping loss to Leicester.
It is understood Forest owner Evangelos Marinakis has started the process of identifying candidates to replace Cooper.
Cooper's position as Forest boss has been in doubt for a number of weeks amid behind-the-scenes tensions after the club signed 22 players during the summer transfer window.
Indeed, Sportsmail revealed on September 21 that Cooper still hadn't signed a new contract that was offered to him in the summer, with a number of clubs monitoring his situation.
