Napoli's aspirations for a top-four finish in Serie A were dealt a blow on Sunday when they were held to a 2-2 draw at home by relegation-threatened Frosinone.

Napoli are now eighth with 49 points, putting them 10 points behind Bologna in the fourth, and last, secure Champions League spot with six rounds left. Frosinone are in 18th -- a relegation spot -- with 27 points.
