The problem with Chivu was always obvious and Inter just didn't care at all. The only team he has managed before Inter was Parma and that was only for 13 games.
Before any of that, he was managing youth teams of Inter, which is of course great because that means he knows the team and everyone in it because he both played there for many years, and then still stayed and spent years managing the youngsters there, meaning since 2007, he has been there for a total of 13-14 seasons with them, so obviously that makes it easier for them to hire him since they know him. But getting an inexperienced coach for the job, when you are aiming for a title, was not a good decision. Season is long, we are going to see how he will do.
That's true, Inter Milan management has taken a big risk by appointing Chivu as Simone Inzaghi successor. Being an important part of the club journey for many years is an advantage, but it's not a guarantee of success. Nevertheless, Chivu has a good squad depth, which can make his job easier, even though many people doubt his managerial quality. We don't know what will happen in the future, but what is clear is that Inter Milan is still considered a Scudetto contender for now.
