The only target for Roma is to become the fourth position of the league so they have a very serious competition with Bologna, although for now Bologna stands on more higher chance to maintain there position because they still have more points over Roma but one of the problem Roma will have is that most of there upcoming matches will be a difficult one for them especially when they will be meeting with Juventus and Ac Milan and without being told we can possibly predict how those matches will end up because the both are very much in a good shape than Roma so that is going to be a serious challenge for Roma to achieve there target.
However in terms of Bologna they are more lucky than Roma through there upcoming matches because from the list the only club that would win or give Bologna a serious tough time is Juventus but after that the remaining clubs are not up to the standard of Bologna so considering this factor I don't think Roma could make it to the fourth position.
If we evaluate the current forms of the teams and the opponents they still have to play with before the end of the season, then for Roma everything looks much more complicated, if only because they still have to play with Lazio, Napoli, Juventus, Atalanta and the match with Bologna will be not less unimportant. In addition, Bologna has a 5-point advantage, which will not be easy to reduce. I even think that Atalanta will have more chances to try to do this than Roma.
There is no doubt that the Roma team is in very good form. Consistently this team is able to perform well. However, it will not be easy to win against Bologna, Atalanta, Napoli and Juventus in the upcoming matches. However, Roma can earn points in these matches if their performance is somewhat stable. Because the overall performance of these four teams is now very erratic.
Bologna will play against Roma, Juventus and Napoli in their upcoming matches. So it is not going to be easy for Bologna to maintain the winning streak. But I would say that the team that wins the Roma vs Bologna match will finish fourth in the table.
