Napoli captain Paolo Cannavaro has warned Roma to expect Saturday's Derby del Sole to be nothing short of a Cup Final.
Although seven points separate the two teams in Serie A, both are vying to qualify for next year's Champions League.
"Saturday will be a Cup Final with Roma," Cannavaro said. "I prefer to only think about this game. It's our philosophy.
"As a fan, I have thought about the Scudetto, but I must reflect in a rational manner. We are doing very well. We have many difficult games.
"We won't pronounce the 'S' word. We are only thinking about improving.
"In the beginning we were considered inferior to the other big clubs because of our squad.
"Walter Mazzarri has given us a winning mentality. Now we are a match for anyone and we have shown it."
