Coaching NT requires less strain than an average football club; we're talking about 1-2 games per month and imho that job is more appropriate for older managers. He wasn't tired, of course. That's a bs excuse. Conte and mgmt didn't get along for some time. My only grudge against him was the time of his departure, should have left earlier if he was unsatsified.
On the other hand part of me is happy that he'll be coaching Azzurri and hope he does well, although current generation of Italian players is rather mediocre. Well known Roman journalist Mario Sconcerti from CdS wrote the other day that Conte is too much of Juventino for the NT job. Suck it Riomerda and Nipples dickriders.
