Toon have lost three out of their opening four Premier League matches and sit in 18th place on the table.
Arsenal are up next for the Magpies, but Benitez is remaining positive about their chances.
"I think it is another game for us. We know that we have to start winning to keep the confidence of our players, our fans, and everyone," he said.
"The training sessions are fine, hopefully fingers crossed the players who are away on international duty will come back fit and right, and then we can work really hard next week trying to do that we did last year.
"Last year, what we did right was to approach every game with the same mentality: that we can get three points from every match, and that's it."
