Inter Milan president Massimo Moratti regards Napoli as title contenders.
Both Inter and Napoli have closed the gap on Serie A leaders AC Milan in recent games.
Asked about the battle for the trophy, Moratti told Inter's official website: "I wouldn't say that Milan and Inter are the only two teams left in the Scudetto race.
"We are closing in but I get the impression that Napoli are playing well.
"This year it's a great championship and great fun because there are three teams in the running. Milan looked like they had opened up a gap but now Napoli are very close too."
