Napoli boss Rafa Benitez admits they were flat for defeat to Parma.
Antonio Cassano scored the only goal of the game.
"I am disappointed, because we did not play to our usual level. It's clear that if we don't play well and our opponents do, then we will struggle," Benitez told Sky Sport Italia.
"We lost the ball too easily, allowed too much space on the counter and wasted a few opportunities going forward with Gonzalo Higuain and Goran Pandev.
"I don't believe Higuain is too isolated, as Pandev was in a more advanced role. The problem was we didn't pass the ball properly."
