Honestly and with all the sincerity of which I am capable, I would never have bet a euro on Empoli. Not only is the difference in strength of the roster of players different and not comparable, but also the difference in club, coach and management. They are really two teams of different sizes, it`s like David defeating Goliath.
But strangely, Napoli actually appointed Walter Mazzarri as a replacement for Rudi Garcia, and I don't think Walter Mazzarri has a good record as a head coach. Because after all, the fact is that the last team for Walter Mazzarri as head coach was Cagliari, and Walter Mazzarri also did not last long there maybe the bad results he experienced. Although indeed, it seems that Walter Mazzarri is also not new to Napoli, because in the past the fact that Walter Mazzarri had become Napoli head coach in the 2009 to 2013 season, and during that period Walter Mazzarri managed to improve Napoli performance by successfully finishing in a better position in each season. But ya, although Walter Mazzarri has good experience at Napoli in the past, but I think at this moment it is still not easy for Walter Mazzarri to provide fast and good results for Napoli, but let's wait.
I honestly don't believe that Walter Mazzarri can solve Napoli's problems in the short term, every time a team changes coach it is heavily affected, sometimes positively, sometimes negatively, Napoli have changed 2 coaches in 6 months and this will certainly influence performances on the pitch but we have to give time and trust to Mazzarri because he is not in a good context, it is not easy to inherit a team that is champion of Italy but has been destroyed in its soul by the previous coach.
