Sheffield United thumped Charlton, whose boss Alan Pardew lost his job after the match.
The rampant Blades went ahead when James Beattie shot in from close range but Linvoy Primus headed an equaliser.
Gary Speed nodded Brian Howard's cross past Nicky Weaver to make it 2-1 and Mathew Kilgallon tapped in after a Weaver gaffe for the Blades' third.
Kelly Youga's own goal and Stephen Quinn's put United 5-1 up before Hameur Bouazza shot the hosts' second.
Charlton manager Alan Pardew:
"Of course I'm going to fear for my position when results have been poor and the goals we've conceded have made it so difficult.
"My ego isn't that big but I still believe in what I can do.
"My record until coming here was very good. This club was on the slide and I haven't been able to stop that."
Sheffield United manager Kevin Blackwell:
"I gave the strikers a little bit of stick this week and questioned their ability to finish the chances we had been creating and they answered me in style.
"I can't say anything other than well done. They have shut me up.
"When things go against you, they go against you. Does that make Alan Pardew a bad manager? No it doesn't.
"Alan has been a good manager over his career. He has proved himself but when you are at the bottom if things can go wrong they will. You always believe as a manager you can turn it round."
