The 28-year-old has yet to score in the Premier League this season, despite featuring in 11 matches for the Magpies.
Recent reports suggested that Newcastle could offload Cisse to QPR in order to sign Loic Remy on a permanent deal, but the Senegal international claims that he will work hard to regain his form at St James' Park.
"I always just keep working hard for the club," he told The Chronicle.
"We have a lot of good strikers here - myself, Loic Remy, Yoan Gouffran, Shola Ameobi and Hatem Ben Arfa.
"But it isn't about who plays with each other - it is about how well we do as a team."
Newcastle manager Alan Pardew has also stressed his faith in Cisse, who has not started a league fixture since October 5.
"We all love Papiss here and I know the goals and success will start flowing for him very soon," he said.
