Vidal posted an angry face emoji on his Instagram story following Barca's Champions League win over Tottenham last Wednesday, when he only came on for the final few minutes.
The Chile international then sparked a fresh controversy after Sunday's draw at Valencia, when he was an unused substitute, after posting and then deleting a message which said: "Don't fight with those who are like Judas, they will hang themselves."
Pep Segura says the posts did more damage to Vidal than to anyone else but backed the midfielder to make amends for his mistake.
"Arturo Vidal's messages have a double meaning," Segura said. "You can look at them positively because they demonstrate that he's a guy who wants to get integrated quickly and help the team. He feels frustrated personally that he's not playing more minutes.
"The negative is we feel he has to work hard and be aware that he's part of a great team, with great players. He has to have respect for his teammates, for the dressing room, the coach and the club.
"We understand that he's aware that those tweets did more damage to himself than anyone else. I think he will make up for it."
Asked if he has discussed the matter with Vidal, Segura added: "We always speak with all the players and these issues are dealt with day-to-day."
