Claudio Ranieri admits to Napoli's Scudetto potential, and has reflected on his previous experience with the club.
Ranieri reiterated a belief circulated by media pundits and even some Nerazzurri players that Napoli are credible title rivals, and Saturday's clash is a title-challenge.
"Yes it is because Napoli has grown. They are doing great things in the Champions League. I saw them in Manchester where they defended before counter-attacking and recorded a just draw.
"Against Villarreal they started strong, showing they have acquired a winning mentality in Europe. As for Inter, I feel this is a Scudetto team now, even though the table says otherwise. For this, I am convinced this is a title-challenge."
It is 20 years since Ranieri coached Napoli.
"Together with Cagliari it was my first experience in a great team. I arrived there the first year after [Diego] Maradona and we did very well.
"I bet on Zola and was right. The feeling of facing Napoli is nice because I remain attached to the teams where I played and coached.
"I'm glad that Napoli are growing and that [Walter] Mazzarri and [Aurelio] De Laurentiis are doing well, but tomorrow we will try to beat them."
