As our skipper on the day pointed out, we dominated the first half and deservedly led through Noureddine Naybet only to let the visitors back into the game as the clock ticked into injury time.
The second half was a different story with an incredible seven goals flying in and Arsenal running out 5-4 winners.
"Most teams would struggle to live with us the way we played in the first half," reflected Ledley.
"The goal just before half-time was a big goal. I'll have to look at it again because I'm maybe at fault for that but if you give the ball away in bad areas they are so quick to punish you.
"It's not the first time the game's been like that against Arsenal but somehow they always seem to be in the game.
"In the second half we were too open, they kept coming at us, we were under pressure and made mistakes at vital times.
"They didn't create too many chances apart from the goals they scored but we were severely punished for those mistakes."
Nevertheless, Ledley insists there are positives to be taken out of it.
"We showed a lot of heart," he added. "When you are 3-1 down against Arsenal you could lose six or seven but we kept digging in, stayed in the game and we believed if we got one back, we could another. We kept going and there was always hope."
In a game of nine goals, Ledley King concedes that Arsenal's first just before half-time changed the complexion of Saturday's derby.
