Roma defender Gianluca Mancini admits there's a calmer atmosphere under coach Daniele de Rossi.
De Rossi remains unbeaten since replacing Jose Mourinho.
Ahead of their Europa League clash with Brighton, Mancini said: The coach has brought freshness, he has brought his ideas and we are trying to understand what he requires.
We are doing so even if we have achieved nothing so far. You don't win titles in two months, but the coach has changed us in many ways, both tactically and in training sessions. The coach has clear ideas. He brought serenity, not because Mou didn't have it, but because results were not good enough. He [De Rossi] has worked on our heads, and when he fixed us, he started saying his ideas.
It's not a four-man defence that made us win six games from seven, but a blend of things. Sometimes, you lose games despite dominating, and other times, the opposite happens. Football is strange, but the most important thing is that 26 players have the same target."
