I personally might understand the reasons behind why the club chose Daniele De Rossi. Because it is this coach who actually understands AS Roma much longer than the others. Because Daniele De Rossi is a former AS Roma player and he played for AS Roma for quite a long time.
And what's more, Daniele De Rossi's contract at Roma is also not a long contract. But only a short contract until June 2024.
So the club is also careful in this regard. And maybe he will consider a long contract if Daniele De Rossi shows good performance as Roma coach for the remainder of this season.
De Rossi is an old Roma player but will he understand how to strategize with the current Roma squad? How is his flying hour as a coach with the senior team, this also needs to be questioned because even great coaches still fail to bring Roma to a better peak but I still doubt De Rossi, but respect the decision of the Roma owner who chose him.
Meaning De Rossi until this season is over? Then Roma management will evaluate whether it is worth keeping or not? I think that still makes sense.
While trusting De Rossi - Roma will look for a coach who he thinks is good in the summer, if for example De Rossi brings Roma better then the possibility will be extended his contract.
