that's one single player, and they've been working together for 4,5 seasons prior to that episode. gasperini has been extremely demanding at atalanta, and his team always was disciplined. my issue with gasperini is mainly the bad matching with our squad: we don't have enough fast, well-pressing players to support his style.
btw conte had similar issues with ziegler or quagliarella, allegri had issues with bonucci and dybala, zidane had issues with bale, ancelotti had issues with a complete club. all of them are generally respected persons. i get your point, but there's no vaccine for disrespect.
