His interviews has gotten stranger past 2 months, he doesnt seem comfortable at all in the position of scrutiny. The pressure and attention is getting to him perhaps.
After 2 scudetto with us and succeeding Conte, I imagine the position of being Juve coach is kinda thankless/hard one to be in terms of receiving plaudites or less pressure. You keep winning the league and no one gives you much of any credit for it as coach, its basically seen as routine you will crucified for if you look like failing (and oh boy does Italy would love to see Juve fail, not out of rilvalry alone but just to say "see, we arent the scottish league yet"). Its the kind of sitaution that requires more of a motivator who reinvents sense of purpose one step at a time, and he was never one.
More ridicolous pressure to boot when your main goal is get CL or its seen as bust season but thats more shot in the dark in knock out rounds and requires bit of key decisive quality we dont have abundance of in some ways like some other few teams do.
He was awful with how he faced the increasing pressure in Milan in last season (melt down levels, was poor with player management too), so even if its a luxury problem for him in Juve, I take it the sense of being taken for granted and not getting much say in mercato will eventually get to this guy more and more. If things become more tense, wouldnt be suprised if he is looking at EPL in very alluring eyes more and more. More of a spotlight, fresh beginning and general huge colosseum for top coaches these days.
