Napoli president Aurelio De Laurentiis has credited the team's position as Serie A leaders to manager Maurizio Sarri.
The Partonopei have gone undefeated in their last 13 league matches to climb to the summit, and De Laurentiis has thanked the former Empoli coach for his contributions.
"It's a first place obtained thanks to the methods of Sarri, which at the beginning of season met a few obstacles," he told La Repubblica.
"Yet today the players are perfect on the pitch. They have assimilated his theories and give a show. Of course I always hope to win, so at Christmas it could be that we'll have more points more than the second-placed team."
De Laurentiis also moved to dismiss rumours linking the club with mid-season transfers, insisting that they have no plans to get involved in the January window.
"The market is only for those who have confused ideas, whereas ours are clear," he added. "This gossip usually comes from the media or fans, who don't live within our dressing room.
"Buying new players to be integrated into this team and get ready and up to speed would maybe mean we rediscover the difficulties of the end of summer."
