The manager insists his first-place side have a long way to go in their pursuit of a first Serie A title since 1989-90
Maurizio Sarri believes Serie A leaders Napoli require more than 90 points to dethrone reigning champions Juventus and win the Scudetto this season.
Napoli stayed three points clear at the top with a 3-1 win at home to Sassuolo on Sunday.
Sarri's high-flying entertainers are yet to lose this season, winning 10 of their opening 11 matches, while scoring 32 goals and conceding just eight times.
But Sarri insists Napoli have a long way to go in their pursuit of a first Serie A title since 1989-90.
