Sarri also spoke of his relationship with the media at an event in Tuscany this week.
“Some things should never come out of the dressing room because a season is also made of difficult moments and confrontations, which sometimes are tough," said Sarri.
“The excessive use of social media makes it even more difficult to manage the dressing room, especially when girlfriends put their hands on it.
“To protect the dressing room is something everyone should do, including footballers. Sometimes those with more personality are not the best players in the group but have a fundamental role in the team.
“The whole environment must work to achieve this target, the coach, his staff and the club."
Sarri was also asked about the relationship with the media.
“It's always a bit conflictual," he admitted.
“It's impossible to have a direct rapport with journalists. Once upon a time, only two or three reporters followed a team. Now, there are radios, TVs, websites…
“The level of professionalism has changed with websites which are mainly managed by kids with no culture or experience. However, I have no prejudice and respect everyone, answering everyone's questions.
“After a match, a coach must do 18 interviews with different media, it's heavy, especially after a game," Sarri continued.
“It's easier after a victory and more difficult when you lose. Coaches want to decrease the number of interviews, but our target is not the same as journalists'.
“I go to the press room to send messages to my players, who are now putting more attention to external messages. If the question is not obvious, I always reply with a message for my players.
“However, most of the time, the level of questions is not that good, and I miss talking about football. Before a game, there are questions on everything except football."
