The Napoli team may not return to play in the UCL next season if Napoli does not get the position currently occupied by Bologna. Meanwhile, Bologna itself still has the opportunity to maintain itself in the top four of the standings, although in general it is still not very safe from the pursuit of AS Roma and Atalanta, who are currently just below Bologna. And I think there will be more competitive competition from these three teams in terms of winning the top four positions this season because the points gap is not too far from Bologna, except for Napoli.
Although the possibility is very small but I think Napoli chances of ending the season in the top 4 are still there, we don't know what will happen in the remaining few games of both teams and if Bologna slip up and Napoli rivals slip up of course provide an opportunity for Napoli to rise to the top rank, currently Napoli have performed quite consistently in the last few games and that positive trend will probably continue later against Torino, If Napoli want to continue to compete for the top 4, it should be for them not to lose points in one remaining match.
This weekend Bologna will have a tough game against Intermilan so the chances for Bologna to drop points in that game Considering Intermilan's unbeaten status in the league since being beaten by Saosuolo, the possibility of Bologna losing points in that game is very big so I think now it depends on teams like Roma, Atlanta and Napoli to how to use that to their advantage to get closer to the United States. Bologna in rank 4 later.
With 11 games left, Roma, Atlanta and Napoli still have a chance to unseat Bologna in Serie A and what they need most now is to play with consistent performance to win.
