The Senegal striker made an instant impact scoring two goals in his first three matches for the Magpies following his £10 million move from Frieburg.
His form since has been less spectacular as he has found it difficult coping with the pressures of playing in the famous No. 9 shirt at the Sports Direct Arena.
He was left out of Alan Pardew's starting line-up in the defeat to Arsenal on Monday and didn't feature as a substitute.
Cisse understands he is in competition with his countryman Demba Ba when Pardew fields just one striker in his formation and told The Daily Mirror: "The manager explained before the match that he wanted to play with just one striker. I respect his choice.
"I already feel I understand the English game, the style of play. It's hard joining mid-season but interesting. You have time to get to know your team-mates for next season.
"I'm hoping I will play better when I am more settled. But I already feel happy here."
His manager Pardew is confident in his signing's ability, saying that the rest of the team need to create more chances for him to be effective.
Pardew said: "The problem we've got at the moment is we're not creating enough chances for him. We're not getting him in a position to score.
"So there's no point in him being on the pitch if we're not able to dominate."
