Can or not Jose Mourinho achieve success at AS Roma, but as we saw he brought AS Roma champions in the League conference last season. So I'm not going to rush that he won't have the kind of success he has at the club he worked for before. But I see the potential is still there, although maybe not like it used to be. We'll see, time will tell.
AS Roma may still need time to win Serie A, because Juventus, Milan and Inter are quite active in the transfer market this season. However, even though they can't win Serie A, I'm sure AS Roma will make it difficult for the top 4 to bring 3 points when face them. This will make the Serie A competition even more interesting to watch. For this season, I'm more confident with Juventus as champions, I don't know, I don't have confidence with my favorite team, AC Milan to get the title again this season.
