Maurizio Sarri's side beat Cagliari 5-0 on Monday to move four points clear of Juventus and the attacker believes they are in pole position

The outcome of the Serie A title race is completely down to Napoli following Monday's 5-0 demolition of Cagliari, according to Lorenzo Insigne.

Napoli have been in fine form this season, winning 22 and losing just one of their 26 top-flight matches to take them top of the table.

The weather-enforced postponement of Juventus' clash with Atalanta on Sunday meant Napoli had the opportunity to open up a four-point cushion at the summit, and they did so with little fuss, winning away from home in comprehensive fashion.
