The Head Coach for the U23 and senior team has asked to be allowed to step down from his role following a run of poor results for both teams
Phuc had initially assured fans that he will not be leaving his post after the defeat to Malaysia in the SEA Games confirmed their exit. But Phuc, who also heads the senior team, submitted his letter of resignation to the Vietnamese Football Federation (VFF), after the end of the tournament.
He was initially brought on, on a temporary basis after the previous national team coach, Phan Thang Hung, resigned at the end of a dismal 2012 Suzuki Cup performance. Hoang has been in charge of the U23 side since 2012 and took on dual responsibility of the national team from January this year. He signed a two-year contract in May but has had a difficult time, losing all of their Asian Cup 2015 Qualifying matches.
"As coach, I take responsibility for this failure," Phuc told reporters after announcing his resignation.
"The entire team tried their best but the results were not as expected. Any excuse at this time is meaningless. I would like to step down.
"My passion is still there. I know the Vietnamese team still has a match against Hong Kong in March but I want to withdraw now so that the VFF can make long-term plans."
Vietnam have won a record seven Silver medals at the SEA Games but have failed to finish in the top three since 2009. They next take on Hong Kong in an Asian Cup qualifier next year.
