The 3 point difference is still thin and can be caught up by Napoli but you know Napoli does not have a busy schedule like Inter they only focus on the Serie A competition but they did not use this opportunity to maintain the top position that they previously occupied I see Napoli starting to be unstable approaching the end like this I don't know what their problem is even in their last match they were held to a draw by a team in the relegation zone.
Napoli started a bad streak, first Osimhen left but it was not so noticeable for their attack, but when Kvaratskhelia left the team, it seems to me that it affected their attack and Lukaku lacks support in attack. I can't say that they started to play worse, everything is not so bad, but their attack is holding them back, there is a lot of confusion in front and few goals, this is the reason for these many draws, where Napoli lose points. If this does not change, Inter will continue to increase the difference.
