First clubs are hard to decide as manager with him, but moving might be understandable as he went up the careere ladder. Atlanta was a miss for him but hey managers must learn from somewhere and not come in as managers wihtout experience.
The Juventus gig was 3 season for him and he was very successful. Left for Itally job(2 years), many would if your homecountry comes calling after very sucessful 3 years in club level. He left Itally as he felt it was not for him and wanted to manage clubs. Chelsea is hard to work in, we all know that. As much I remember none of his transfer where able to get and he had Drinkwater bought in... Inter ended because of bad owners and financial shitstorm they are in, with open sale they are having right now.
I think people considering him as short term manager are wrong. Definetly I missed some issues etc he has had but in bigger picture he has image wrongly put on. He is and will be VERY hard manager to work with and someone who will never hold back. But those are his idellogies and ways of managing. He expects respect and honest from the club. He is very much like Bielsa in this regard. How many have told he is too hard to manage and think his transfermarket avarage term could be even less as he quit after 2 days
He needs club that believes his methology and back his vision. The same reason why Bielsa is one of the top managers, but it is just so hard to fit in modern clubs and owners whos structures are so rotten from bottom to top.
