De Rossi is having not good reputation, but he can do something special which will help him for having better things for his and his team future two wins bring some positive change and their test case is ahead while they will host Inter Milan.
De Rossi is a coach who still doesn't have much experience as a coach. Of course it is normal for us to ask, is he worthy of being AS Roma coach? the same goes for other new coaches such as Pirlo, Seedorf, Gattuso etc. So far, the one who has the potential to become a good coach is Simone Inzaghi, while his brother Filippo Inzaghi is also having difficulties. Roma was quite brave in their decision to make De Rossi the interim coach, but if he succeeds in improving Roma's position by the end of the season, maybe De Rossi will start to have confidence in being the coach of a Serie A team.
If it was another team less competitive than AS Roma in the Serie A, I will say two match is enough to give a new coach the confidence to lead that team, but for a team like AS Roma, he has ti face big teams like Inter Milan before one can ascertain that he can lead the team to success if left as the head coach of the team throughout the season. I know it is very difficult starting to coach a new team even when you haven’t had a lot of experience prior to coaching the team, but his ability to win one or two tough matches will make him be at advantage of staying long in the team and finding a comfort zone for himself to continue his coaching career. The next three games of AS Roma will say a lot about De Rossi’s coaching career in the team, especially the one against Inter Milan.
Roma have won their last two matches 2-1. Roma have won two matches after losing several matches in a row. But in both the matches, the opponents were very weak. Roma team wins against Verona and Salernitana.
I agree with you that whether the new coach is still successful will be seen after watching Roma's performance against Inter Milan. Roma's new coach is not experienced enough. I don't even see the possibility of Roma winning against Inter Milan. Because Roma could not dominate the match against Salernitana. But against Inter Milan, Roma will probably play defensive and try to get 1 point. And the match is highly likely to be a draw. But I look forward to seeing if Roma's defense can perform well against Inter Milan's strong attack.
