The match against Inter Milan at home will be the biggest test for De Rossi because the rivalry between the two is quite prestigious and As Roma must win if they want to catch up in the standings. It feels a little difficult because Inter Milan are in good form at the moment and De Rossi will definitely have a hard time facing them.
It was a very large test and almost impossible to complete. How could you give the match against Inter as a test for De Rossi? I mean, even if Roma loses the match, it doesn't mean that De Rossi is unable to carry out his duties well because the opponent is Inter Milan, the strongest team in Serie A at the moment. Maybe we can use the match against Ac Milan or Atalanta as a test for De Rossi to show the development of the team he is coaching. Or at least the match against Feyenoord in the European league. I think it would be more appropriate to look at De Rossi's capacity as the new coach of As Roma.
This means how far De Rossi has prepared to face Inter Milan, who has performed well this season. Beating Inter Milan is certainly a very difficult mission to carry out, but it is not impossible for Roma to achieve victory when facing Inter Milan because in football anything can happen. De Rossi's challenge is not just to achieve victory over Inter, but he must be able to make Roma provide balanced resistance even though they know the team they are facing is very difficult to stop. Even though Roma lost to Inter Milan, they had to lose in an honorable way. This means that losing by a narrow score is still considered normal, but if Roma suffers a big defeat it would be very embarrassing, this is what is meant by the test for De Rossi.
