Vidal played for Conte at Juventus.
"I have experienced a lot of nice things with him. Thanks to him I became one of the best," said Vidal to El Mercurio.
“In football, the most important thing is to be trusted and if a coach has got that faith in you, it makes you grow a lot."
On Barca, he added: "I have worked hard my whole career, my moment hasn't arrived yet, but I'm calm, as I know it will.
“I don't seem to find an explanation. There are different ways to look at football, these are the decisions a Coach must take. I try to help the squad when I'm called upon."
