Benitez's men take on Roma in an early clash between title rivals next Friday, but Higuain believes that the game will be important rather than decisive to their Scudetto hopes.
He told reporters: "Yet, it is indisputable that it will be an important game, capable of sending an additional signal, but nothing more, it is not final.
"The season is very long, there is no eventuality that will change my mind, whatever happens. We need to at least wait until the end of the first half of fixtures to sense the true forces and then even that may not be enough.
"But anyway, I am generally not accustomed to the interest of others, I am thinking about my team, to improve, to grow through training."
Higuain has wasted little time in making his mark at the Stadio San Paolo, scoring four times in seven appearances for Napoli in all competitions.
