Nathan Jones assessed tonight's defeat at The Valley, as the Addicks exited the Emirates FA Cup in the third round at the hands of world champions Chelsea.
Charlton started well and kept the visitors quiet until stoppage time in the first half. A late flurry meant the game finished 5-1 which felt harsh on Jones' side.
He said: "For long periods we were good. The game plan worked, we nullified them to certain things. The goal before half-time was a killer, but it was a good strike.
"The second and third goal killed us, and it was poor defending from the set play. We can’t allow him to run in front of us like that, and that is why they scored.
"We then got ourselves back into it, and then the third goal is the one I have sleepless nights over. It is stuff we have conceded from before; to concede from that, it was a non-learning and that for me is the biggest disappointment from tonight.
"The second and third goals was the real turning point, and we have to do better from them."
The Charlton Manager was able to take some positives from the fixture.
"Off the ball we were excellent," he explained. "We defended in the middle of the park really well, against world class players.
"The way they moved the ball and worked, you can admire, but we aren’t at Premier League level yet. We are not in that position yet, and we have to understand that. There are lessons we need to take from that today. They are a great group, and structurally we were good.
"We started well; we had all the moments early on. The noise [in The Valley] was phenomenal, and I took it in.
"It is my job to make sure that we learn, and we that we don’t make mistakes."
Both Amari'i Bell and Tyreece Campbell limped off in the second half.
Jones said: "I am hoping the squad looks different and that Amari’i [Bell] and TC aren’t serious. Hopefully in a week, we should be in a better position."
