I will actually not say that he has failed Roma. Because in my opinion, he is doing quite well. Of course, he is not doing incredible. But Roma is currently in the sixth position of the table. I will actually call that respectable. Even though they have not been able to be very consistent, I think they have the capability of improving. The problem is this season the competition is very big. A lot of teams are performing very well and better compared to the last season. So that might end up being a problem for Roma.
He failed to bring Roma to top four of Serie A and they could not join Champions League in this season. In general he succeeded with Roma because he brought them to two final matches in Europe: one in Conference League and one in Europa League in two consecutive years. He won one Conference League with Roma and it is a first title of Roma in Europe through their long history. It is a great success for Roma.
This season, they are competing for top four again and this race again is very tight among many clubs. I am unsure that Mourinho can succeed with Roma and end this season in top four.
Inter is also my favorite team in the Italian Serie A. They were a great team last season but this season they have become a better team. They are my favorite not only in the Italian Serie A but also in the Champions League because Real Madrid and Manchester City are going backwards in football this season while Inter are going forward. They haven't conceded a goal in the league in the last 4 weeks. I think they will beat Genoa tomorrow and consolidate their lead in the league. They are like a machine, I don't think they will make any mistakes this season.
Inter Milan are one of most strongest and stable teams in Serie A last four seasons. They won Scudetto 3 seasons ago, ended as a runner up 2 seasons ago, and in the last season they ended in top four and also had a final match in Champions League.
This season, Inter Milan show they are really strong in Serie A and will continue to be a big hope for Serie A in Champions League. Their opponent is Atletico Madrid that are not weak and with defensive style of Diego Simeone, Inter Milan will have more difficulty to beat the opponent from La Liga.
In Serie A, I believe Inter Milan will be a biggest barrier for Juventus to win Scudetto. It's very high chance for Inter Milan to beat Genoa and create pressure on Juventus that will have a big match against AS Roma.
