Sassuolo often give surprises when facing big teams in the league, but for some reason I don't think this will apply when facing Napoli later, currently Sassuolo performance is too bad for us to try to bet money for Sassuolo win and we can see in the last few weeks that even they only achieved 1 draw, 5 defeats from 6 matches and it will probably get worse when they face Napoli, which on paper is certainly still better than Sassuolo at the moment, even though Sassuolo acts as the home team, it doesn't seem like it will have a bigger impact for them and my prediction, the match will end with Napoli winning 1-3.
Changing coaches in a short period of time is of course a gamble for Napoli and it could be said that management dismissal of Garcia and Mazzarri was a form of disappointment from management because of the bad results obtained by the two coaches, many people claimed that the change of coach was in the middle of the season only makes the club unbalanced, but in fact there are also clubs that really recover when the coach is replaced as happened with Roma, currently Napoli game is starting to be a little different even though haven't given maximum results in their last two matches, but I'm quite confident that Calzona will able to return Napoli performance to a better level in the next few weeks.
Napoli were going through a tough time and this prompted the call up of Mazarri. At his debut game, he did well to win, even though much is expected of him, he just shouldn't be blamed if up until now the team are struggling to be consistent in victories. At least they're not always loosing games. They've got some wins and some losses too. Even when they played away from home to Roma who were a better side too so definitely it'd have been difficult for them to win although a draw wouldn't have been much of a bad result. The Italian side recently haven't had good strides in their league tussles and it's effect is gradually going to be seen.
They ought to cover up their lapses but they aren't having what it takes. It'll only cost them a lot if care isn't taking to repair these losses. There's no time left and their contests on the league tables are shaky, Mazarri only had to find a way around his team to cushion the drastic effects of their recent performances but since he couldn't they had to get a replacement that'll be able to place them rightly. Well the new coach hasn't really made any big impact but so far, the team's performance have been better, they're even far more competitive and aggressive on the pitch as they used to and kudos to their forward man and the team in general who have been striving to remain at the peak of their performances.
One would hope that this tempo is maintained till the end of the season because it's only that way that the team would finish at a meaningful spot in the Serie A table. Their forth coming games hopefully will derive a better results for them at the end of the season too but if they can successfully conquer this season to some reasonable extent, it'll be advisable that they work generally on the management aspect of the squad as positive changes would need to be made by next season.
