Roma managed to defeat Cagliari at home with a single goal. With this win in a week when Lazio lost points, the points difference between Lazio and its rival has decreased. The current standings show a 2-point gap.
Fiorentina managed to beat Juventus at home. Honestly, I didn't expect Juventus to lose because Fiorentina came into this game a bit tired. That's why I think everyone expected Juventus not to drop points, but Fiorentina surprised everyone.
Roma's victory was not so surprising because from the start they were already very favored, especially now that Roma's performance is quite improving and now Roma is in 7th place in the Serie A standings and 4 points behind Bologna who is in 4th place in the standings so I think that will be a target for Roma and with the strength that Roma currently has I think it is still very possible for them to finish in the top 4.
And Juventus' defeat was very embarrassing, they are not like a top team that is improving its position or competing at the top, Juventus' performance is indeed very bad and very inconsistent so even though Fiorentina won the match easily, there is no conclusion that can be drawn because Juventus is indeed very bad.
