Miroslav Djukic has left his job as coach of Valencia.
In a press conference televised on the club's official website, Djukic said he was the only one to blame for the decision.
"I have not managed to put Valencia where I said when I arrived, so I'm the one to blame," he said.
Club president Amadeo Salvo confirmed 33-year-old Estevez had assumed Djukic's responsibilities while a permanent successor is sought.
