As is the case with most teams in the lower reaches, Sunderland arrived at the Lane determined not to surrender any more ground in the quest for survival.
"It was never going to be easy and we knew they would come here to battle," agreed Ledley.
"Once we managed to keep up with their work ethic we started to play some great football and open them up."
With the score at 3-1 and over 20 minutes left on the clock, Ledley insists that a touch of showboating was never an option for the defenders at least.
"Some of the lads might have done - the midfielders and forwards - but not the defenders. It was a nice game for us."
Called up by England for the friendly against Australia on Wednesday, Ledley does not feel that he yet back to his absolute best after missing the beginning of the season with a hip injury.
He is, however, growing in confidence with every game.
"I always felt that it would take a few games to get back my sharpness and form. I'm not sure that I've reached it yet but it is coming back, so that is a good thing."
England-bound Ledley King says that matching Sunderland's work ethic was the key to convincingly overcoming the Premiership strugglers.
