The Black Cats were completely outclassed by the Magpies and Bruce could only look to their next match where he holds hope that his players are able to respond to such a poor performance.
"The mark of any team or any individual is how you respond to it," he said.
"All I can do is apologise. When you get beaten as badly as that, here of all places, it will take a lot of recovering.
"Me, as manager, I will take full responsibility. Anything that could have gone wrong went wrong, from red cards to mistakes.
"I have been saying all week that we must handle the occasion. But from the off, we didn't and we got blown away by a far superior team on the day.
"We were playing a big derby game and we had three or four players. To win it, you need seven or eight - that's what Newcastle had and we didn't have enough and we got our backsides kicked."
