The midfield in-particular refused to let Nicky Butt and Jermaine Jenas settle with Jermaine Defoe and Fredi Kanoute doing the same to United's defence.
That pressure led to the winning goal with Jermain chasing down Celestine Babayaro's back pass and keeper Steve Harper's clearance rebounding off Simon Davies for Jermain to tap home.
"It's something we talked about before the game," said Ledley, the skipper outstanding again in central defence alongside Anthony Gardner against the threat of Alan Shearer and Shola Ameobi.
"Newcastle had a tough game on Thursday and we thought they might just be a little jaded so it was our plan to go straight at them from the off.
"We did that in the first half and then picked it up again in the second half.
"It was pressure from the lads with the idea of forcing mistakes. That's how we wanted to play against them. We forced the mistake, pounced on it and at the end of the day that's the goal that has won it for us."
Ledley King revealed how pre-match plans to put Newcastle under pressure worked a treat on Sunday.
