Enayat continued Bonyadifar was among the 15 individuals who were picked that 6 of whom were to be sent to the seminar in Britain based on an agreement between AFC and Britain's football federation.
Enayat also added UK embassy refused to issue visa for the Iranian referee although Britain's football federation had contacts with the embassy and sent letters for it.
