That's right, Napoli made mistakes in the last 4 matches imagine they only collected 3 points from those 4 matches this means they are opening up an opportunity for Inter Milan to take over the top of the standings until this actually happens Inter Milan lead by 1 point. Napoli still have a chance to take back when both teams will fight each other next week especially Napoli will play at home but from what we can see lately I have little doubt that Napoli will beat Inter Milan and I think the best result is a draw.
I did not see such a performance from Napoli at all. I agree that they have not been doing well in recent games but I can’t just believe that a team that was almost the best could fall so quickly and even lose to a team like Como. If they had lost that game to Lazio but had won this one then that would have been better for their image. There are games where weaker team can beat stronger team but we have to acknowledge that the players themselves are responsible for this decline to some extent.
Sometimes a weak club can give an unexpected surprise like Como did and many people do not believe something like this can happen and most likely considered lucky even though a weak club itself cannot be considered weak forever there are times when they rise and play their best game when facing a club that tends to be stronger and I think Napoli underestimated Como so in that match Napoli was quite sure they could win but it turned out Napoli was quite careless and finally Como gave fierce resistance in that match and was able to win the match of course this was a proud victory for Como because they were able to beat the top of the standings.
Como might be considered a weak club by you, but what they did to Napoli was the same thing they did to Milan, Fiorentina and Juventus. Como got all three points from these four strong clubs including Napoli, so I am not surprised. However, when you underestimate your opponents, you will end up been defeated. Napoli wasn't serious in this match, and it has cost them losing their position to Inter.
