The Senegal international, fast becoming one of the best signings of the season after arriving from Bundesliga strugglers Freiburg in January, scored in each half to give Alan Pardew's team 56 points from 32 matches.
"He was our best player today, of all our flair players he was the one who was really on his game," Pardew told Sky Sports. "We are lucky to have him and he deserved to be named man of the match.
"As a team we were flat today, some of our flair players lacked a bit of energy but we have a lot of discipline and camaraderie in this group."
CISSE'S DELIGHT
Cisse went close to a second goal in the 65th minute when he sent a fierce low drive whistling past Vorm's right-hand post.
"I thought we totally outplayed Newcastle and the only thing we couldn't do was put the ball in the net and find that little bit of quality in the final third of the pitch," said Rodgers.
"They were two outstanding finishes by Cisse, real quality. It stuns you a bit when you dominate a game like that but that's football sometimes."
