according to italian media he lost the trust of the players after that famous press conference.
I don't want to say that he did right, but in Italy he behave also worse than that with many players, like insigne
(after a substitution the player had something to say and sarri in the press conference declared "insigne is a player, I'am the coach and I decide so he has to shut up")
the difference between napoli and chelsea was that the president de laurentis backed his coach's decision,
the board of chelsea is absent and this is the problem.
I respect the fans' decision of chanting "fuck sarriball" but maybe they should reflect on this: benitez=guilty ancelotti=guilty mourinho=guilty conte=guilty sarri=guilty
the board=perfect
