I also think about this, Roma and Bologna in terms of performance have better quality than Napoli, Napoli need to work hard to overthrow the position of the two teams and take fourth place, on the other hand I am sure Bologna will not quickly be complacent about fourth place what they get, they will fight hard to move up further or at least stay in their current standings
One thing I like about Bologna is that they are very strong and really want to maintain their current position against their competitors and they are doing very well so far. Seeing Bologna who are unbeaten in the last 7 matches makes you wonder what formula they use so they can be this consistent. The reason is that not a few mediocre teams like them can last longer and they are even now sitting in the top 4 by facing several other strong teams. Even other teams such as Roma, Atalanta, Napoli and Lazio have to shift each other so they can immediately shift Bologna's position.
Here Bologna certainly wants to continue the winning trend that they have worked so hard to build and the next realistic target for them is to be able to overtake Milan. That is something they can achieve in the near future and they just have to wait for Milan to experience a deadlock so they can get closer. I am happy that Serie A shows competitive competition and seeing these teams continue to compete until the end of the season it will be increasingly difficult for us to predict who will secure a top 4 place later.
