I also think Napoli has no chance of winning with Lazio in super form as they are now, sad but true
Among other things you can see Lazio more fluid play while Napoli is still looking for its balance (and isnt finding it at moment)
agree with you in the end
Lazio @2.25 and Napoli @3.30, even though Lazio is the favorite, but considering odds like that, of course Lazio is also not fully projected to win. Because yes, with odds like that, it is also possible for this match to end in a draw. After all, currently Lazio position in the Serie A standings is actually better than Napoli, and currently they have a gap of only 2 points. Therefore, even though Lazio is the favorite based on the odds but yes, it will still not be easy for Lazio to beat Napoli in this match. But indeed, at least even without considering the available odds, I am also more confident that Lazio deserves a chance to win this match.
Napoli had a huge fall, they went from the title winners to now looking ninth I believe? I mean it looks like we are talking about a huge deal here, that type of fall is not that easy, you have to be specially terrible to have that kind of situation.
All in all, I believe that the best thing to do right now would be just making sure that Napoli has abetter future set, maybe try to get that manager back so that they would be properly coached again. This is why Lazio winning could make sense, but Napoli doesn't have a terrible squad neither, not that they did alright this season, but that is not mainly because they couldn't, it was mainly because they wouldn't, if they really want to win, they may end up getting a win, so this is a bet to be careful about.
