Roma and Bologna will both have difficult matches this weekend and I think nothing is impossible for them even though these two teams are in a fierce competition and really need a win but at the moment some teams are in different form so it is quite difficult to predict.
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.
