Don't underestimate underdog teams like Bologna, however, football can still give surprises, even teams with no experience can still compete there if their performance is impressive and that's what Bologna is doing now, they are performing impressively and consistently so they managed to occupy fourth place even though they still have a long way to go. long and AS Roma and Atalanta still have a chance to take that position but Bologna also still has a chance to maintain their strength and for Napoli I don't know whether next season they can compete again in the UCL because their performance is not so stable.
Bologna may be the underdog team when they face Inter Milan later, but overall Bologna is a pretty good team this season and Inter Milan must remain alert because Bologna managed to beat them in the 16th round of the Coppa Italia which caused Inter Milan to fail to advance to the quarterfinals, even though in the end Bologna also had to accept defeat from Fiorentina in the quarter-finals and Bologna was quite strong when facing a strong team, especially when playing at home, Bologna performed better than in the away match so Inter Milan had to be aware of all possibilities.
Inter Milan probably won't be too worried in the match against Bologna because the 15-point lead over Juventus will not be easy for their rival to catch up with, less is possible but being surpassed by Juventus can be said to be impossible so even if Inter Milan gets a draw it will still make them comfortable at the top of the standings.
Bologna being chased by Roma looks like it will be difficult because Roma has just improved in the last few matches, so it is not certain that their performance will continue to be as good after being handled by De Rossi.
