VFF vice-president Nguyen Lan Trung has confirmed about this. Right after the Bulgarian coach arrived in Ha Noi this afternoon, he had a meeting with VFF officials to discuss about the vacant post as head coach of Vietnam national team. No agreement has been reached but a final decision is expected to be made in next 2 days. Reuters also reported about Stoichkov's arrival in Vietnam.
Just a few days ago, German coach Falko Goetz's representative was seen in Vietnam. The former Hertha Berlin coach is still biggest candidate for this position.
