I also think Fiorentina played well enough to win but they could not get win and had to settle for tie. This is disappointing because they needed win to try to get spot in the Europa League. Lazio has tough game against Inter Milan so Fiorentina tie could hurt their chances. Napoli did good job coming back to tie after being down two goals but they have not won in six games which is big concern. They were the champions last season so it is sad to see them struggling. It is looking like they might not even finish in top eight which would be very bad end to their season.
Even though they are not very satisfied with the draw that Fiorentina got at home against Napoli, Fiorentina's opportunity to reach the Europa League zone is still not lost if Fiorentina can win in the two remaining matches this season. I just saw that Fiorentina's last match this season will also face a fairly difficult team, namely Atalanta, who is currently still in the top five, so Atalanta also doesn't want to lose at home because Roma is still a threat to Atalanta, who is currently in sixth position.
