Napoli extended their lead at the top of Serie A to four points on Sunday after beating lowly Verona 2-0 as champions Inter Milan moved second with a 1-0 success at Venezia. An early own goal from Verona goalkeeper Lorenzo Montipo and Andre-Frank Zambo Anguissa's second-half rocket ensured that Napoli took advantage of Atalanta being held to a goalless draw at Udinese on Saturday and strengthened their bid for a second league title in three seasons. Napoli's lead isn't as imposing as it looks, however, as Inter have two games in hand, the first of which is against Bologna at the San Siro on Wednesday.
