I still think that Inter has a bigger chance, yes Napoli has been doing great recently and they have a new manager and doing fine and all but the reality is that we are talking about the league leader here, not some small mid table or bottom of the table team.
Inter is great, Martinez is scoring like crazy and they have a bigger chance to win. Osimhen has been looking terrible this season, I said that Napoli should have sold him this summer when they had the chance, there were great offers, they rejected the offers and because of that now he worths a lot less, what did they gain from keeping him? There were two possibilities, either you keep him and win something with him and earn more which seems not happening or you keep him and he keeps playing amazing and he worths more which looks like not happening neither. This is why it's quite obvious that we are talking about something that will not be all that easy to handle and should be a problem for them.
Yes, and at the same time, the team performance from Inter does look a lot better compared to Napoli. The current form also looks better. so I am going to say that it will be inter who will win this match. But I still think that the match is going to be very close. And one key thing that you mentioned is Osimhen not being able to perform well. He was a key player for Napoli. And if he is unable to perform, it definitely is bad news for them. Because he is the one scoring most of the goals for the team. And at the same time, the striker of their opponent is playing really well. So things are not looking good for Napoli at this moment.
