Maintaining the team's performance will be much more difficult for De Rossi and they cannot afford to lose good moments like now by experiencing bad things. We don't know for sure what will happen in the future and I hope the club management can provide funds for spending next summer so that next season they won't be left behind again. Roma's next match will be against Cagliari and of course with De Rossi's new strategy, Roma will still be able to win whatever the conditions.
But inevitably De Rosi must do that because now in the first 2 Serie A matches and 1 friendly match they are playing well and now De Rosi must continue to try to maintain this performance even though it will certainly be very difficult for them with conditions that are still under pressure but there is no other way if he really wants to prove that he deserves to be Mourinho's replacement at Roma now.
There are still several matches they have to win including maintaining the condition of the players because in addition to Serie A of course the hope of qualifying for the round of 16 phase in the Europa League is also still there, it's just that the opponent is very heavy but this is a test for De Rosi because if in the end he is able to boost Roma's stagnant performance under Mou then of course in terms of popularity he will move quickly just like what happened to Xabi at Leverkusen.
