Benitez helped the club to a third-place finish last term, and the 54-year-old is confident that his side can scale the same heights this time around.
"No, I don't feel any risk at all," he told reporters. "I've not spoken with the president (Aurelio De Laurentiis), but I don't need to speak to him every minute to not feel at risk.
"I am the coach of a strong team that did well last year and they will do well again. We're still playing at a high level, we just need to keep the faith."
Napoli are without a win domestically since their 2-1 opening-day victory away to Genoa.
