He also attacked the board under Sethi for inducting "tainted" players in different roles in the PCB.
Prime Minister Nawaz Sharif had in February removed Ashraf as the PCB chairman and appointed Sethi in his place to run the affairs of the PCB.
Sethi, who now heads a managing committee to run the PCB’s affairs, on Monday appointed former captain Moin Khan as chief selector and manager.
"I left Pakistan cricket in good standing. But it has gone down," Ashraf said in the statement.
"When I was the chairman, Pakistan made a historic clean-sweep against world number one England in Tests,” he added.
Ashraf said the team was united in his time but now things had changed and there was discord within the side.
He cited Pakistan's early ouster from the recently concluded World Twenty20 as an example of the discord that has since bred in the squad.
Taking a dig at former captains Shahid Afridi and Shoaib Malik, Ashraf said it was surprising that the team performed the way it did despite the presence of ‘three captains in the side’.
"These captains were playing for their personal causes instead of team's cause. I felt disunity and fear within the team," he said.
