Yes, you are right about this, I saw that in this match Salernitana played very well and put a lot of pressure on Roma's goal, so that Roma's back line seemed to have difficulty in Salernitana's attacks. I saw that in this match Roma's performance and consistency did not look good, because against Salernitana, whose position in the standings was very different, Roma were still confused by Salernitana's attacks and not only that, Roma also had difficulty scoring goals against Salernitana. However, I really appreciate Roma's victory in this match, even though Roma have not been able to give their best performance, at least they are still trying hard to win this match.
Regardless of whatever happens, Roma can win this match and that is the most important thing.
Regarding Salernitana being able to put up quite a strong resistance, I think this is a natural thing because even though Salernitana is a bottom team, they have great motivation when they play against a Serie A team so the match is fierce and that has been proven this season.
Roma's two consecutive wins with new coach De Rossi are certainly a good start and will thereby increase the team's confidence as they look towards the next match.
The opponent faced by AS Roma is still a weak team. 2 wins can be obtained from Verona and Salernitana. 2 weak teams that should be easily won by AS roma. salernitnatan is currently ranked at the bottom of the last rankings while verona is currently only ranked 16th, 2 levels from the degaradation zone.
