Napoli coach Maurizio Sarri has dismissed critics who say Inter Milan are boring, saying they play "decent" football.
Sarri, whose second-placed side take on leaders Inter at the Stadio San Paolo, said Roberto Mancini's side, who have won seven games 1-0 this season, were "very efficient."
"They are physically very strong and a solid side, but their football is decent," he told his prematch news conference.
"I've seen Inter's recent games and they are a very efficient side, particularly when they accelerate, so we're going to have to be very careful. It's a very dangerous game for us."
Sarri said he was looking forward to a special occasion, adding: "I love these games. It means we're doing well, and I'm delighted to be able to savour an atmosphere like this."
But he played down talk that the match could be important in the destination of the Serie A title, saying: "There are still 25 games to go, so no matter what the outcome of this one it's not going to affect us psychologically for the remainder of the campaign."
Meanwhile, Mancini said critics of his side's football could say what they wanted -- but that he would settle for another 1-0 win in Naples.
"You need a bit of everything against such strong opponents as they are," he said at a news conference.
"Everybody sees the way you play the game in a different way, but whoever wins is the better team. I don't know Sarri very well, but the results say he's a great coach."
He said he believed there were "three or four sides better than us" but that Inter would "give it our best shot" this season.
