Can we all agree that Ac.Milan vs Fiorentina should be the game of the weekend in Italy ? I say this because even if Milan is not in a great shape , they always had a rivalry with Fiorentina and with only 3 points that separates them , I have a feeling we will witness a crazy game with both teams to score and a big surprise with Fiorentina winning the game climb up to 3rd spot. 
Yes, Ac Milan should be able to win and bring home full points in the match against Fiorentina, because there is a big match this Sunday between Atalanta vs Napoli. Of course this will be the match that fans of the Italian league have been waiting for because Napoli is only 2 points behind. with Ac Milan, if Ac Milan fails in the next match or draws against Fiorentina, if Napoli brings full points at home to Atalanta, of course it will shift the standings in the 13th match. Of course, Napoli will also focus on other leagues such as the Champions League. Likewise, AC Milan also has to focus on the Champions League with a difference of 3 days from local matches, even in the Champions League they compete very closely with the difference in points with their competitors.I can say it was an amazing start for Walter Mazzarri in Napoli, After all the points they lost with Rudi Gacia, it seems Walter Mazzarri is in a better situation in Napoli because Rudi didn't have a good relationship with other players and it was a reason for Napoli to et him but with Mazzarri they don't have any of these problems.
Napoli has been performing a bit better compared when rudi was there. The new coach seems able to understand what players wanted. So, it was giving positive vibes to the club that is significantly affecting the performance from the players.
The only problem that needs to be fixed if napoli shall able to create more chances. Napoli was dominating the match against atalanta with more ball possession but it was unable to create more chances than atalata. This is the main problem that needs to be sorted out by the new coach of napoli.
So far so good. The new coach was able giving three points against atalanta which is one of strong club in serie a at this moment. Atalanta is also considerably as a black horse this season.
The stats are also better compared when rudi was still coaching the club. Sometimes, you shall try to take the risk if you were willing to change anything. No pain and no gain.
The club needs to sacrifice something to get a better result caused by this is football when everything still remain unpredictable.
