The Morocco international, who joined the Stregoni on a season-long loan from Newcastle, has managed nine appearances this season for the bottom-placed club.
He said: "Sincerely I tell you Napoli. They have a great playing style, they never throw away the ball: I like very much their football.
"Even when they are in their own box, they have the personality to go out with the ball on their feet, with their intelligence and with the technique they have.
"And even for the forwards they have, it's not usual that they score less than three goals in one match. They really impressed me."
