The former Sunderland ace admits it was a special result for him.
Henderson said: "I spoke to one or two Sunderland players after they won at Newcastle and they were delighted with the result. I watched the game on television. This was a great result for them but the main thing is it was another good result for us to win here.
"It was a great performance from the team from start to finish. It was important to finish the week on a high. On a personal note, I was delighted to score the two goals as well."
