I admit that De Rossi was really quite successful with Roma, what De Rossi did was not an easy thing and he is able to prove it now even though many people doubted it at the start.
Bologna suffered a defeat and that means that the distance between Bologna and Roma is currently only 3 points, with 10 matches remaining I am quite sure that De Rossi will be able to bring Roma to finish in 4th place in the standings.
De Rossi will have a successful season with Roma if he can help the club to take either a fourth or fifth position and be qualified for Champions League 2024 - 2025. Potentially Serie A will be given a fifth ticket to join Champions League next season if their clubs play well in Europe and maintain its ranking against other top leagues.
Roma are contributing for Serie A in Europe too so De Rossi will have double tasks with Roma, in Serie A and in Champions League. To be sure of qualified for Champions League, they need to complete Serie A in top four.
If this mission fails, it's hard to say De Rossi has a successful season with Roma no matter how many impressive performances he has with them.
In fact, Bologna's defeat yesterday by Inter Milan was an opportunity for Roma to reduce the difference in points so that it would be easier to catch up and shift Bologna in fourth place, but the result was that Roma only drew with Fiorentina, but that was not a bad result either, De Rossi has indeed shown the best game of his team, therefore he must maintain it so as not to lose points, let alone suffer defeat because that will be detrimental to Roma in the future. They must be able to finish in the top four at the end of this season, which is certainly an easy thing.
Bologna's unbeaten record in their last five matches was finally tarnished by Inter Milan, now Roma has a difference of only three points with Bologna, meaning it is clearly not more difficult than before that Roma has a chance to finish in the top four, De Rossi must be able to show his quality to be a coach for Roma in the future and he has raised Roma from their previous downturn when Mourinho served as coach there, since De Rossi took over Roma they have performed better from time to time, if you look at Roma's development now I am sure they will be able to finish in the top four in end of season. because they deserve to be there.
