take out Gasperini out of Atalanta and hire another proper coach and they will be the same. Its not one player or person which makes the club work, its the entire structure. They have good work ethic and they care about their players and its just works thanks to this.
Then look at us, we had an injured Milik, who according to the reports didnt even get a proper support from the club, he was wrongly diagnosed for this injured by some doctors (not sure if club ones), finally he has received some proper treatment in Barcelona (yet he is still not back).
And Milik is just a one case, but really shows the club is not there to help the players, if they cant help a player in such critical situation when what does happen with every day problems?
New players come and almost all of them have problems with settling in, its visble, because Koop, Luiz, Nico arent as bad as they are showing.
Also the constant banishing of more experienced and distinguished players might also be not helping keeping the right atmosphere in the team.
I think we have an institutional problem here, rather than coach or DS problem.
