You can't complain about that to the players, they did not start the season in a good way but they later on they began to win many matches and climbed to 3rd position, i believe they would have continued playing that way and would have finished second or third
Juventus players played well to move closely to AC Milan but the accident caused them a painful punishment with 15 minus points that sink them down on the table. With it they will not be able to move closely to top four in near future and might be end this season with a position not in top four.
Roma are up to 4th position on the Italian seria A table now, they have 37 points, just 1 point behind Ac milan that is second, so they may even finish in second position this season, i am very happy for Mourinho, i know his ambition with Roma this season is to bring them back into the champions league, and i believe he would do that.
Roma have improved their performance with a return of Paulo Dybala who is very important for them. More fortunately, they got benefit of Juventus punishment and take over the fourth position. Roma can climb up to a third or even a second position in next few weeks if things go smoothly for them. Same total points as of Inter Milan and only 1 point less than AC Milan, Roma suddenly see their chance to be a runner-up in this season.
