I don't think Inter Milan management choose to make Chivu their head coach as a thing of favor or compensation because the Serie A is becoming more competitive, and Inter Milan management wouldn't appoint Chivu as their head coach if they know very well he won't perform well at Inter Milan this season. If Inter Milan plays 10 matches this season in Serie A without Chivu gathering a convincing point, Inter Milan management will likely relieve Chivu of his job and hire another coach who can be able to deliver what they want.
No team appoints a manager out of pity or some sentimental bias except for expectations of delivery, this is business and they can not afford to mix in emotions with business where good funds has been invested, the reason Inter appoint Chivu as solely results oriented I believe, everyother is mostly not the primary reason why. And I want to believe even Chivu does understand this and will want to make sure a substantial amount of points would have been gathered after a good number of game has been played so he does not risk his job
Inter certainly recruited Chivu for a reason, especially since Chivu, like Inzaghi, is a graduate of one of Italy's top coaching universities, and Conte is one of the most successful coaches to have graduated from there. So we can conclude that if they graduate from there they have a good understanding of tactics.
Furthermore choosing a coach without experience coaching a major team is still a gamble. This is evident in Inter's poor start to the season, with one win and one loss in two matches. The current problem is whether Inter management can be patient if coach Chivu doesn't show any improvement in the next 10 matches. Inter must not fire their coach mid season, so Chivu must immediately give his best for Inter in the coming matches.
