The match vs Girona is Roma first match without Mourinho in the team coaching chair, this time Roma will be accompanied by a new coach who does not have much experience as a coach. Roma's journey this season has become increasingly difficult due to the team having to adapt again to the strategy used by the new coach. The statistics of both teams will probably lead Roma to victory, but there is no guarantee that Roma will be in the top six because there are still many problems being faced after Mourinho's departure.
maybe you mean Verona, not Girona.
we may not know whether Roma will be successful under De Rossi but from the upcoming match we can at least see clear evidence that Roma can beat Verona with a big score at home, meaning De Rossi has little influence on Roma performance but if Roma losing or only winning by a narrow score, I'm quite sure that De Rossi still needs time.
I never doubt anyone's coach before playing a few matches, but after reaching 5 matches, Roma doesn't get any improvement or even experiences a drastic decline. I will guarantee that Roma will fail to get a ticket to the UCL or the european league.
the reason I say this is because this match has entered the second half of the season and the problem is very bad, management cannot retain Mourinho at least until the end of the season to get a ticket to the UCL or european league, but in fact the management let Mourinho go, even though the coach was very influential on the future of Roma and although De Rossi is a legendary former player but he does not have good achievements in the past.
