Cristian Chivu has considerable experience, having previously played for Roma, Ajax, and Inter Milan, so that experience is sufficient to give him a better chance given Inter Milan's current strength.
Napoli is indeed the favorite due to their consistent strong performances over the past few seasons. I'll stick with Inter Milan this season, even though I have my doubts. That's understandable. After all, we know that not everything can be positive; he'll have to adapt as a new coach.
Speaking of experience as a player, Cristian Chivu can be said to have quite a bit of experience. But I think his experience as a coach is still quite limited. So, we shouldn't really expect too much from the current Inter Milan coach, Cristian Chivu. His extensive experience is that he coached the Inter Milan youth squad from ages 14 to 19. He then coached Parma, and now he's back at Inter Milan, specifically the Inter Milan senior team. And while I don't have high expectations, I hope he succeeds.
However, if we're talking about whether Inter Milan will be able to compete closely in Serie A and the Champions League this season, my answer is actually doubtful. Because I think it's still quite difficult.
