Fulham defeated Leicester 2-0, handing Ruud van Nistelrooy's team their seventh consecutive loss at the King Power Stadium.
Foxes fans aimed chants at the coach and the board, booing and jeering substitutions as the game was taken away from them in the second half following goals from Emile Smith Rowe and substitute Adama Traore.
The win moves Marco Silva's side up to ninth but the focus of most inside the ground was on the failings of Leicester.
They remain only two points from safety but in far worse form than any of their relegation rivals. Despite a promising start, Van Nistelrooy has four points from his nine games in charge.
Timothy Castagne almost scored an unfortunate early own goal on his return to Leicester, while Victor Kristiansen curled wide for the home side with his weaker foot following a good run. But the afternoon unravelled for the Foxes once Fulham went ahead.
Good work from Raul Jimenez and Harry Wilson led to Sasa Lukic sending the ball into Smith Rowe's path to nod home. Soon afterwards, Wilson's cross found the unmarked Traore at the far post to volley in a second and the mood became bleak in Leicester.
The withdrawal of Bilal El Khannouss had already led to chants letting Van Nistelrooy know they questioned his decision-making abilities and there were more jeers when Jordan Ayew was taken off - in the fans' view, belatedly - for the popular Facundo Buonanotte.
It was not only the Dutch coach who was the focus of the ire with chants for the sacking of the board recurring throughout a second half in which Fulham appeared far more coherent. The boos at the final whistle only underlined the fractious atmosphere.
Steve Cooper was hardly beloved by Leicester supporters but it is worth remembering that he left the team outside the relegation zone after a dozen games. The situation has deteriorated since he departed and Van Nistelrooy is under real pressure now.
