Richard Keys has said Nottingham Forest boss Steve Cooper is "working in a madhouse atmosphere" at the Reds this season.
Cooper masterminded a remarkable revival at Forest last season which saw them rise from the bottom of the Championship to a triumphant return to English football's top flight through the play-offs.
But the Reds are in real danger of dropping back down to the second tier as they currently sit in the bottom three on goal difference. They have failed to win in their last 10 matches, having last tasted victory back in February against Leeds.
