De Rossi might be able to stabilize the team. But the Roma team is not strong enough. Roma management should definitely take necessary measures to strengthen their squad. If the squad is not strong, it is not possible to get consistent good performances from the team.
De Rossi might be able to bring As Roma to win the UEL title next season even though the competition is also quite tight next season without Leverkusen and Atalanta, of course As Roma must prepare their full strength to be able to get better results, De Rossi may also need financial support to be able to do so. A bit of an overhaul and recruiting several new players to make As Roma's game even better next season, De Rossi so far doesn't look bad as a manager at As Roma and gave good results at the end of last season.
The new season is coming, of course De Rossi has to prepare everything for a better change, at least he can get a pretty good ranking in the domestic league as well as in the UEL, at least he reaches the UEL final and fights for the trophy, As Roma has that opportunity and of course they can't waste it. This is another opportunity to become the best team in UEL next season. I think As Roma is an Italian team that might give a surprise in the UEL next season as we saw Atalanta win the UEL title this season, no one knows it's all full of surprises.
