I enjoyed watching this game. Mourinho has brought that mentality of winning and playing for purpose in that Roma team and its something that has been lacking for them. Roma has improved in every aspect and for sure they can challenge for the title now with the players they have in their team, even if they won't win any but they can bring up a fight that will make them title contenders.
They are among best candidates for top four and Scudetto. They still need to improve more. Top four is in their hands but Scudetto is a bigger challenge for them.
With Mourinho, Roma defense is better and they have become a more dangerous team. They don't need to have good ball posession to score goals or to get points. With an effective counter attacking that is still improving, Roma now is better to collect points. They know how to protect advantage from their leading goals. Eventually, they avoid losses and get more wins.
