The Senegal international has failed to score in his last 13 Premier League fixtures with the Magpies, netting only one in a Capital One Cup win over Leeds United.
"I will score goals this season," Cisse told The Chronicle. "I have not forgotten how to score a goal. I believe in myself and I feel I am coming close to good form. I am sure it will happen for me soon."
Cisse scored 13 goals in 14 matches in his first season for the Magpies when he moved to St James' Park in January last year.
