I don't think, Lazio can close this gap 19 points to take over the first position from Napoli in the Italian league table because Napoli are very ready to improve their points more to maintain the position till the end of the tournament. Napoli strikers are really helping the team in the areas of goals because they always make their fans happy in every match by defeating their opponent with many goals that will increase their points. If Inter coach can work on their midfielders and strikers before their remaining matches, I think they will definitely take over the second position from Lazio.
In the next matches, Napoli's match will be difficult. They will face Milan. Inter will play with Fiorentina. At this stage, the easiest opponent will belong to Lazio among these three teams. Lazio will play Monza. Currently in the second place Lazio and Inter will stand better in second place if the probability of losing points is realized. Of course, for this, he must first beat Monza.
Even though the match will be difficult, Napoli will still relax at the top of the standings without having to worry about being almost 20 points ahead of second place. Napoli just need to be prepared to lift the Serie A trophy because this will be a historic moment since the last time Napoli win the league in 1989–1990.
Speaking of Milan, this could be part of the preparations for the two teams to meet in the UCL quarter-finals next month.
