AS Roma will not experience more problems if De Rossi is able to train every player who comes to AS Roma very well and is also able to make the players who are still remaining at AS Roma into players who have quite good contributions and achievements in the team. And everyone will see how AS Roma will be in next season because AS Roma still have to be able to face the fierce level of competition considering that many of their rival teams will still be strong next season.
If De Rossi is able to produce good results like he did last season. So Rome can indeed be expected to experience even better improvements. And the players brought there in the transfer market this time should be able to adapt quickly to the way De Rossi trains the team. Because it seems like De Rossi is always able to establish good relationships with the players. But I don't think we can make too quick a judgment about De Rossi for next season. Because next season will be De Rossi's first season in building a squad in Rome. Because last season the Roma squad was built by Mourinho and De Rossi just continued it. This is different from next season where De Rossi will have a tougher challenge because the squad has been reshaped by him. Although maybe something hasn't changed. But some players are leaving and some new players are coming.
