Segura believes Vidal is insulting his teammates with his antics on social media. The Chile international has complained about not starting in recent games.
"The situation of Vidal is very clear," Segura told Sport. "In the first place, with his messages, it is a proof that he has the personal will to play and serve FC Barcelona to win everything, as he said during his presentation.
"But the negative part is that he does not have the behavior that a professional must have out of respect for the coach and his teammates.
"In a club as big as Barça, with such great professionals, Vidal knows he was wrong and he showed disrespect to his teammates. But I'm sure he'll correct that."
