Talking about doubts actually in this case I saw from the beginning when Spalleti left that many doubted Napoli because they would experience a transition and it did happen and after a few games done at the beginning of the season towards the middle of the season now it continues and surely the doubts continue to grow as time goes by.
Yeah, because this doubt is quite basic. how we see Napoli's condition this season, how they failed with the first coach who replaced Spalletti, and how they also failed several times even when there was a new coach, Mazzarri. This time it will be very difficult for Napoli to win the Schudetto title again. This seems impossible...
Although there are some matches that Mazzari has let slip away without full points at the moment I still wouldn't say he is a failure even though this possibility is quite large because after all when looking at the situation now Mazzari will actually still be considered a form of adaptation for him and indeed this is not going too well.
But what is certain now regardless of whatever happens is that Mazzari will still be behind Napoli's coaching at least until the end of the season because honestly I doubt if Napoli will change their coach again even though they failed because after all it is not too ethical to see a change of coach done very quickly for a big club like Napoli especially this also refers to their finances of course.
