Yes that's right. De Rossi doesn't have much experience in coaching, let alone coaching a big team like As Roma. Imo, De Rossi was only made temporary coach by AS Roma, AS Roma will look for a coach who has experience in domestic leagues and inter-European leagues.
But even so, his debut as coach of As Roma went very well, Roma was back on the winning track even though the opponent they faced was a weak team like Verona, but this was a good start to increase the players' confidence.
And on his first debut as coach, the differences between coaches Mourinho and de Rossi were clear. Mourinho often brings Elsharwy on from the bench while De Rossi plays from the start, this is a good decision in my opinion because Elsharwy has good stamina.
De Rossi's contract may only last until the end of this season. But I am sure that if it turns out that De Rossi is able to bring AS Roma to good results in Serie A then maybe he can also get consideration for a long contract or contract renewal. Because for De Rossi, becoming a coach at AS Roma is a great opportunity in his career to train at a higher level than usual. So it is impossible for De Rossi to waste this great opportunity.
Because even if in the end De Rossi doesn't get a contract extension from AS Roma. But if he has shown good results during his time as coach at AS Roma then there will definitely be other big clubs who will look at him and offer De Rossi a training contract.
AS Roma currently also has an important match in the Europa League and this will be a big challenge for De Rossi who has minimal experience. So that you get more experience.
