Honestly, Napoli really tried, but as you said, they were not just lucky. Napoli was the team that controlled the pitch,and they even created some chances, but they were not just lucky to score. Just imagine Napoli having six shots on goal target but being unable to score even one goal, but Bologna, who had just four shots on goal target, was able to score two goals. I also saw it as lucky that they worked on the Bologna side in today's match. Seriously, despite Napoli not being great this season, I did not expect Bologna to defeat them in their home game; all I was expecting from the matches was a draw because even Bologna's form has dropped. Now that Bologna won Napoli, I think that chances of finishing in the top four have seriously increased. If Bologna can win their next match, they will secure a place in the next season's champions league.
Yeah, honestly, this is such painful to see how the defeat experienced by Napoli this time. They lost to Bologna 2 goals whereas they actually have so many trials to score the goals. unfortunately, they were not able to optimize the shots. I'm not sure that Napoli striker or other attacking lines are such bad this time. I'm not sure if Bologna is lucky or whatever the name, ut I see that Bologna was much better to optimize the chances than Napoli. And Bologna was smart enough to utilize the chances to make goals, 2 goals, not only because of luck, but because their big efforts. 
It seems like they no longer have high motivation to win because their recent performance has really dropped drastically. Even though they have changed coaches several times, it still doesn't work. Do they have to bring in Spaletti again so they can get back on their feet? Will the results be the same as last season again if Spalletti coaches Napoli again one day? Such painful to see how Napoli right now.
