To be honest, I'm surprised Fiorentina could win in the first half... I don't watch this match, but I thought Napoli would take the three points, because Fiorentina have the final of the Conference League soon... I thought that this match doesn't mean anything for them, because they are in the Conference League zone anyway...
It is no longer strange if Napoli lose because they have never won for 5x matches only able to collect 3 points from 5x matches this is a bad season so I don't dare to bet on Napoli because the results will definitely be disappointing.
While Fiorentina to prepare for the Conference League final is still long and they can still win for Serie A matches even though this is not something important, but I feel Fiorentina getting points is important for them to add confidence in the final later.
Edit: Napoli equalize to 2-2 as this match will be interesting.

Napoli was able to equalize the second goal to give them of of winning or drawing the match if they don't male any mistake that will lead to Fiorentina scoring them the third goal. Napoli was lucky that Belotti foul that was given to Fiorentina when he was bought down inside Napoli box was canceled by the referee, because it was a minor contact.
However, Fiorentina is pressuring to see how they can gain all three points in this match but Napoli will not let that happen. Napoli missed some good chances, and they are suffering for it now. It is 90 minutes and 5 minutes extra time have been added. It is still 2-2.
