Napoli have a number of advantages to get the Serie A trophy back and maybe the effort will be a little more convincing after they managed to take the top position from Inter Milan again. Now what Napoli needs is to play consistently until the end of the season and must not make any small mistakes in order to maintain their chances. It is not an easy job but they can definitely get through it if they are consistent in the remaining matches for this season.
Inter Milan themselves will be fighting in the Champions League so their focus will definitely be divided, so this momentum can be utilized well by Napoli. However, a great effort must be made because if you make a mistake, the opportunity will be lost and Napoli must not do that.
Perhaps this is the only advantage that Napoli has, that Inter will also devote a lot of energy to the Champions League matches, but so far they have been able to distribute their forces well for both tournaments. It seems to me that Inter is better assembled as a team, especially since they are more cohesive and in decisive matches this can play a role, but for now Napoli has two points advantage, this is not so much and on March 1 Napoli will host Inter, in this match a lot can be decided.
