Former Siena and Palermo boss Giuseppe Sannino believes Napoli will struggle to win the Scudetto this season.
The Partenopei drew 2-2 with Milan on Saturday and currently sit in fourth place in Serie A.
But the 55-year-old Coach is of the opinion that Walter Mazzarri's side must improve if they are to challenge for the Scudetto come May.
“This is a League where you can no longer take anything for granted,” he told Radio Crc. “Napoli have started at 1,000 miles per hour, but sometimes you have to compromise.
“They drew with Milan at the weekend, but you can't judge them at this point in the season.
“They have had two positive results recently, but from what I've seen I think they will struggle to win the League.”
