Juventus is very lucky to have been in the position they are right now otherwise they wouldn't have made it to the top 4 again with the bad performance they have recorded lately, the matches are remaining few they can end up dropping more points for Bologna to be ahead of them but they will definitely be in the top4 like wise bologna but since the matches are still remaining for them to play, Roma till have good chances of being among the top4 but their chances depend on the results of Juventus and bologna.
The top four are mainly for the club's that's clinching for the UEFA Champions League spot for next season. I know it's difficult but they have to make attempts. Juventus have declined in performance, it's been one of the poor performance and terrible season. The Old Lady's have fallen from the top competitive clubs for the scudetto, lifting the title does appear to be impossible for them this season. They have Inter Milan ontop and we know how challenging it will be for these clubs to continue fighting for titles without actual hardwork to reach far this season.
There is no point in discussing the scudetto winner it definitely has Inter Milan this season they would end the season with a good record of 1-3 losses while Juventus is only focused on staying in the top 4 which I'm sure they will be safe, what I'm worried about is that Bologna is not yet safe I've been saying this for the last 2 months especially now that we see that AS Roma is playing consistently.
It is clear that AS Roma has the ambition to play in the Champions League next season, we can see this determination next month when the two clubs fight each other in April one of them will lose points and AS Roma as the home team will take advantage. One win was not enough for AS Roma they also had to wait for Bologna to be beaten by Juventus and Napoli towards the end of the season because Bologna only has 3 strong opponents in the remaining matches.
