Napoli coach Edy Reja believes there's more to come from his team after Sunday's 5-0 win at Udinese.
Reja said: "To win 5-0 away from home, against an important opponent like Udinese, is a result that lifts our morale.
"But we cannot take too much from the game. I already said after the debut against Cagliari that this team has remarkable room for improvement and I say the same now that we can and we must improve.
"The win on Sunday was beautiful, but in order to know the true Napoli we need time."
